*** Galaxy Tab Master Tweak Thread***

Hi everyone.
Id like to start a thread where we collect, post and discuss all known individual tweaks and changes that can be made to the Galaxy Tab in order to gain performance and stability.
My experience with the Galaxy Tab has been similar to my latest phone, an HTC HD2. When I got the HD2 about one year ago, I positively hated it... slow, unstable, all sorts of problems, lags, crashes... its the way most of the hardware today is released. One year later, my HD2 has become the most amazing machine I've ever owned. From pushing it 1.6GHz stable, to tweaking registry, XML files, services and making everything work well. I remember not being able to watch smooth video on the HD2 to being able to watch flawlessly 720p content and going from the extreme of detesting the phone to loving it.
It was with the HD2 I discovered Android and fell in love with it. Since I have now two HD2s I have one with an SD ROM version of Gingerbread (that I can dual boot still from Windows Mobile) and a Froyo NAND. I run Android on the HD2 much much much faster and smoother than on the Galaxy Tab, that I also hated when I bought it a few weeks and that am starting to like after getting to know it, a new ROM, apps, etc. Even at 1GHz stock the HD2 with Froyo is vastly faster, smoother, more responsive and better to use. The approach d like to do as far as tweaking the Galaxy Tab is the same as I did for the HD2 with Windows Mobile, that is, install the best/fastest ROM I can, delete and remove all stuff I don't need and then tweak what's left.
The tweaks I've done so far on the Galaxy are simple but have made a huge difference. Id like with this thread to be able to collect individual tweaks and post them all here to share with everyone.
Im using Roto JMI Pre-Rooted Firmware v2 which was the main step after getting rid of the stock Samsung Rom that is nothing but a collection of problems.
The first thing I learned with this Tab is that WHATEVER IS ON YOUR HOME SCREENS THAT MOVES, IS BAD! Forget about having ANY type of apps or widgets that do any type of refresh, including stuff running on the upper task bar if they change icons or the move around… that mean a CPU cycle and refresh each time and there goes the tab's performance and battery life. The same goes for any type of Live Wallpaper. Beautiful but deadly. Never touch them!
- So, after a new ROM, the first thing I did was changing the file system to EXT4. This is the SINGLE BEST THING you can do to radically improve the performance of the Tab. Its extremely easy to do and the step-by-step instructions are as follow:
- Make sure you have an miniSD Card in with plenty of available space (it will be used automatically to backup your system during the conversion process)
- Get p1000-mck-r3-ext4-cwm.tar (the EXT4 Conversion Kernel)
- Connect the Tab in Downloading Mode to your PC via USB, start Odin3 1.7 and load the Kernel (click on the PDA button and select the p1000-mck-r3-ext4-cwm.tar and make sure PDA stays ticked after selecting the file).
- UNTICK Re-Partition check box and make sure the only boxes ticked are:
Auto Reboot
F. Reset Time
The PDA tickbox
- Click start and wait for PASS! (it will show highlighted green or Yellow on Odin)
- Now the Tab will restart and get stuck on the Samsung loading screen. This is normal. Turn it off by holding the power button for 5 seconds.
- Turn on the Tab again on into RECOVERY mode (Press Volume UP and Power On at the same time) and the EXT4 conversion will start automatically. The process will take up to one hour depending on how much stuff you have on your Tab. It took about 10 minutes on mine because I have a fresh install of Roto JMI v2.
- Once finished, click "Reboot System Now" (by pressing the power button).
- The reboot may take a while first time so be patient!
- Done!
- After that, the first tweak I did was to get rid of all my favorite widgets that moved around… net meter, news, weather and all these beautiful things KILL the Tab. Equally I had a CPU meter on the tray refreshing every 2 seconds and it took me a while to figure out that was the reason why every 2 seconds the system would stutter, whether watching a movie or browsing the web. So, out!
- Next was to install SetCPU under the ON DEMAND setting, minimum around 750MHz and maximum 1000MHz (unfortunately only with a custom Kernel you can go higher, currently up to 1.4GHz but not full stable and with lots of issues pending so I don’t recommend it)
- My following step was to get rid of the stock Samsung Homescreen (that is a resource hog and slow as hell) and replace it with a new one. I've tried them all and am making no recommendation here but the one that works for me and is by far the best IMO is LauncherPro. This single app makes using the Tab a whole better experience.
- Next was to disable the USELESS and (resource pig) Gallery and replace it with an app called QuickPic that is blazing fast (actually instant) and simply amazing to browse and view all media on the Tab.
- Next was to greatly improve the poor native GPS reception by replacing high performance files and drivers from the Orange Rom P1000JHKA1 that seems to work on all versions of the Tab, as originally posted here:
http://forum.xda-developers.com/showthread.php?t=922692
- With SystemApp Remover 4.12 I have disabled all system apps and services I don’t need (BE VERY CAREFUL AND DON'T REMOVE ROM APPS YOU WILL NEED). I have actually deleted some from ROM (Root access required of course), this includes useless stuff like STK Service starting every time, most of the Samsung stuff that I really don’t care for and just about all apps I know for sure I will never open a single time. Now, its important to understand if these apps are removed they will be removed PERMANENTLY from ROM so to get the back a hard reset will not be enough, you'll have to fully flash the ROM again. For most system apps I don’t use but am not sure, I use a different option and that is to simply disable them. In my case this includes all Bluetooth stuff (I never use it and even if it's off the Services are still running robbing performance and memory) and apps like the built-in Browser, Email and Messaging that suck and that I replaced with better apps. Its always a safer bet, at least initially to disable the apps you don’t need that uninstall them because at least you can go back and change your mind This is one area where Id like to learn more. There are many background services that I don’t know what they do and if they can be disabled or not. If someone knows what each one does and the safety of getting rid of them OR NOT, it would be great to post it here!
- Them, with Startup Auditor 2.3.2 I have disabled all unnecessary apps that start automatically every time the Tab boots so I don't have excess applications starting up that are not needed. Some I configured to be killed AGAIN if the system tries to restart them later after the boot-up
- Using Task Manager 1.0.7 and letting always run on background, I have configured all apps that I don’t need running to be auto-killed every time the phone goes to stand-by (screen off). This saves me lots of memory and CPU time on apps that I am actually not using.
- Finally, I monitor what is going on with an app called CPU Usage Timeliness Free 1.7.1.0 and use it to see EXACTLY which applications are using CPU cycles and interfering with performance. With it I have found that on my Tab I have an unsolved problem that is using over 100MB of memory and non-stop CPU usage between 15% and 45% of something called SECURITY STORAGE. I have no idea what it does. It can't be disabled and I don’t know where all the activity comes from. If someone know more about this and how to fix it, that will be great. Most of the performance issues I have on my Tab come from this Service that I don’t know how to tame. Surely, we can find a solution.
The system background services is one area where I'd like to know one by one, what each service does and if we need them or not, if it can be tweaked, disabled or deleted. Below is a complete list of the services I have safely disabled so far that have given me great performance boosts and with no negative issues on the system (IN BOLD), and OTHERS I WOULD LIKE TO KNOW MORE ABOUT (not bold). Please note these are background services that start automatically. The changes made to the disabled apps/services is that they are reverted to ON-DEMAND so they all still work perfectly.

Originally with my Tab I was getting Quadrant below 600 on average. Now, its always over 1900. This is not a "little" improvement, this is amazing upgrading. But id like this to be a starting point to learn and share more ways with everyone we can all share on things we can do to make the Tab as good as it was intended to be for everyone
Cheers!

1.4 oc is stable, and doesn't have any issues for alot of users.
all the things you disabled are all the things i use every day lol
never the less, good post, im going to use a couple apps you mentioned.

The first block of disabled items (in bold) from CALENDAR to WORLD CLOCK are disabled start-ups but the apps works as usual. It just frees resources not required on boot till you actually start the application when you want.
The second block from Bluetooth Services to Voice Search are all disabled as I use none of those. Items disabled can be restarted again at any time upon activating them follwing a reboot, while items deleted (like Samsung Apps and STK) are gone forever.
Ive never flashed a ModaCo Kernel and got lots of feedback regarding probelms with 1.4OC. Do you have any issues at all or none? We are using different ROMs... What Quadrant do you get currently?
Cheers

Thank you for your post.
You have solved many of my questions. Also I am User of HD2 and had the same impressions, but now with Android Nand everything was great, also started to love it.
As for GTAB'll make those adjustments you suggested, some will not disable because I use Bluetooth as an example.
Any news please keep posting.
Success!

So far the oc is good, things load a little faster, especially nfs shift. Last run of quadrant was 2300-2400.
Ill try it again later after these optimizations and see how it goes, a member here has gotten 3000.

Having done nothing but root, my tab gets about 1000 quadrant score. I have tried setcpu using on demand and it actuall has made my tab worse. I am very hesitant to flash anything on the tab. It seems very involved and complicated. I have an HD2 as well and have been flashing since Android was on SD. That process is simple. Everything I have read about flashing things to the tab doesn't look that way. I really havent had any issues with my tab as stock other than a bit laggy at times. I would like to hear more about all of this. The oppinions I have read are either do it or don't do it. There are more problem posts after attempting to flash than there are good ones where it worked. I really could care less about a quadrant score to be honest, but I would like to have a faster smoother running tab. I really dont care about making calls on it either. Thats why I have a phone. JMO. I think part of the issue in this thread is that there are Euro and USA version which are completely different and require different roms and such.
I have been reading and lurking in the tab development thread for a while now and am not impressed with any of it yet. Maybe someone could shed some light on things and change my mind.

I agree. The process of flashing the Galaxy is much more dauting than anything on the HD2. I suggest you do the EXT4 file converstion. All you need is follow the step by step I wrote above. It makes a huge difference. As for everything else, I too hold off to do too much flashing. The ROM I use now is great and lighter than stock but your seems to work well so keep it. For me when a ROM is good I just use it. When I bought the HD2 I flashed it 2 times with a custom ROM till i found one that worked for me and kept it for 8 months. But backing up and restoring WinMo is much easier... on Androind its all more complicated if you dont know what you are doing. Disable some start-ups on your unit, convert the file system to EXT4 and make sure you have nothing on your home screen doing a lot of refreshing and your tab will work great

Is everything working 100% on that ROM? I do not want any ROMS that are having problems.

I too am not impressed with anything that us out yet...seems like any ROM process is tedious and complicated.
Glad the thread starter modified his tab to his liking, but what's the point of having it if you need to drastically change everything. I have a rooted DInc and not use any of things......didn't really see a performance gain with set CPU.
I'm going to continue waiting for something more reliable and use my tab the way it was meant to be, with all its hardware and widgets.

Thank you for your detailed post. While I agree with you that the stock SGT rom and browser suck but where do you think the JMI, JMF, JMx ROMs coming from?
Most ROMs I've seen (except for CM) are based from some sort of Jxx
Please keep the tweak posts going. Good stuff and thanks!

Not impressed with all the problems being posted just tring to flash it, and how complex it is to do it. Guess that's what I meant. Flashing the hd2 is a very simple process. Tab is not

My boy,
Only getting my Galaxy tomorrow but looking through threads on my favorite forum.
And guess the first one I happen into... I will follow avidly.

Hi dubie76,
Try an app called OCLF 2.0 on the Market. It is a Lag fix app for the Samsung Galaxy S which also works on the Tab.
https://market.android.com/details?id=com.rc.QuickFixLagFixR2
You have to install EXT2 tools and then install one click lag fix, both are done within the app.
I had this on my Tab before flashed to a custom ROM. The tab was much faster and did not have and lag compared to stock, the Quadrant score was around 1900.
Also you can uninstall the modifications in the app and easily reverse back to stock. The only disadvantage is you will loss about 800mb of internal memory (the 2Gb space), so if you don't have much space left, you will need to uninstall some apps and reinstall them once you applied the lag fix.
P.S. thanks to OP for the SystemApp Remover & Startup Auditor suggestion.

Custom ROMs?
Hi everyone!
Consider this:
The locked GTab (in standby) on an original ROM with a connected to it BT headset wakes up after replying a call from BT and can potentially have anything pressed as being in the bag due to its size...
My point is that there is NO fix for this on XDA therefore why should I expect any significant advancements from a custom ROM if such simple things cannot be fixed on Android.
My personal view is that Android is unfortunatelly not as flexible for adjustments as WinMo (i have HD2 as well with a wonderful custom Artemis ROM).
I've tried two Roto ROMs on my GT and they havent provided any noticeable enhancements in performance to my eye (perhaps some rating went up - I dont care about tech stats). I reverted to stock ROM P1000XWJMI that works as fast for a "regular user".
I am sad to resume my experience with hacking the GT as not worth it: you get serious risk of getting the GT bricked (much more complicated than with WinMo), loose the warranty and are open for instability and sudden incompatibilities with crashes.
On the third custom ROM installation attempt I was stuck on a black screen after powering on (stuck on the bootloader!) and couldnt initiate flash for multiple times. I was shocked and very nervous. Thats when the stock ROM saved my ass and I am not willing the risk of playing around any more with non-firmware ROMs for Android GT.
Regarding the alternative screen lockers available - please do not suggest Screen Suite (the best of the worst) and things like No-Lock (to get rid of the original locker) as they all mess up once in a while (tested) with the default ROM settings and the original core locker.
PS
In my view the best thing we can and should do first of all is to COMPLAIN to SAMSUNG Tech Support and Software Developers (I did twice already).
If every one of us from theese GTab forums would do this they would definitely get faster with resolving issues.

Buyers guide (Galaxy S2 review vs iPhone4)

Hi guys,
I thought i share my thoughts and experience with people who have not decided which phone to buy. Maybe my input will make the decision easier (or maybe it will confuse you even more hehe).
Also I am hoping people with Android experience maybe can assist me with some of my negative bullets. I'm very new to Android so i apologies for my mistakes in my so called review/comparison.
And lastly i dont want to start any fanboy android vs iOS. This is just my personal view of the two phones/OS'es. Its maybe a bit unfair since i been using iPhone for the last 3 years and Android for only a week but still some of the bullets are independent of that. Any how lets dig into it, First i take the negative side of SGII and next the positive sides.
(maybe my topic is a bit misleading but below some of the items are compared against iPhone but i wont write all the plus/negative for iPhone since the SGII list is already pretty big and i want to focus on SGII which i hope can replace my iPhone)
- When i exit USB mode (where i can access the SD card) i cant find a way to reconnect it without cable unplug->plug. Is there a way i missed?
- Browser doesnt word wrap the text/column so good on table tab. I had a side by side comparison with my iPhone4. On iphone the whole article including images are resized and the text is fully readable. On Galaxy S2 images are not resized and text is readable but just barely. So the whole screen real-state is not fully utilized with the lower resolution and bad browser formatting.I have tested Opera also but the whole word wrapping experience left a very bad taste in my mouth. It was the worst experience ever, the article jump up and down every 5 sec or so, i think the browser got confused for some reason and couldnt decide how to format the page (this was when double tapping).
- Default browser crashes (go to qj.net where i usually visit to read about games).
- Text selection is a pain sometimes. First problem is that in every app it behaves differently. Second problem is that the process to select a text isnt so smooth.
- Confused about task and background proceses that start magically! When using taskmanager i can see mostly 2-3 tasks there and this makes sense. Now using other task killers suddenly they show 10-15 tasks. I understand these are background task but its beyond me why some of them suddenly are there. Like Kies, this should never be started unless i am using Kies. I can see now why my battery goes dows so fast (well compared to iPhone again). Why is there so many tasks started and why cant i control them from vanila Android. This should be a must. I dont want to root my phone to do the basic settings.
- Pretty much all application is downloaded can only be installed on phone memory. Why doesnt Google enforce developers to adapt to new versions of Android is beyond me.
- I havent found a way to backup everything on the phone (including applications and their save data) to my pc/mac. Without this i dont like to experiment rooting and other shizzles.
- Apps are not as smooth and functional on GS2 compared to iPhone4. Ex: Tunein Radio, i cant skip to next song. Ex2: ign app (iphone) allow for daily videos while the Android version is very poorly done and dont have any videos. Feels like Everything works just a little better on iPhone compared to Android phones.This is something most people cant understand if they havent had iPhone for a long time i think.
- Slow battery charging. I usually start charing at around 20% battery left. In one hour GS2 reaches around 40-50% while iPhone goes to 80%
- Headset lacks volume + next/back track when playing music.
- Creating folder through Kies Air not possible. for ex in media make a folder called movies.
- Drag&Drop in Kies air missing.
- When uploading a file through Kies Air there should be a progress bar, now it just looks busy and you dont know if its uploading or it hangs.
Ok now to some good sides on the Galaxy S2:
+ Brilliant screen (even if i think resolution could be better)
+ Flexibility and open market for every sort of application. Much like windows here you can add more functionality and make the phone very personal.
+ Excellent codec support. It plays pretty much everything i through at it. Well done Samsung.
+ Very good camera (even better then iPhone i admit)
+ Very good video recording (also better then iPhone)
+ Very light
+ Feels pretty good in your hand (even though i’m afraid one day the backvocer will break, i had a Nokia N95 and one day the smal plastic edges broke when i was opening the cover. Same thing will happen ti GS2 i’m sure)
+ Expandibale uSD.
+ Very cool fearure called Kies Air where i can access most studd through browser. (this can also be added to minus since it doenst work perfectly everytime i tested but the potential is there)
+ Nice features like pinch effect for desktop + many nice widgets.
+ I think you can make proper call recording on SGII (CallRecorder) but havent confirmed myself yet.
Lastly i like to say SGII is a wonderful phone and i really really want to use it as my primary phone. The one thing i hope Samsung fixes that will make me more loyal to Android is the default browser. The text wrapping must be improved and the browser more stable. I like the smoothness of the default browser and this is the most used part of the phone and so far my iPhone is better but i hope 2.3.4 update maybe can improve this.
Any input, tips, tricks are welcome. I really appreciate your help.

Hopefully this will help you, at least in some areas (i numbered them in the order that you have used):
1) using developer mode at least (i prefer it as its faster and more compatible than samsung's stuff) you can mount/umount at will the card on the pc via the phone without unplugging
2) You may want to try Opera Mobile, it seems to do a very good job at this. I'd like to see this in the stock browser too, but hey, this is Android, you have the choice to change the browser if you like ;-)
3) Well, same thing I guess. 2.3.4 may improve stability but the rest, I don't know, I wouldn't bet on it. I like Firefox quite a bit as well, but text wrapping is odd on it.
4) Android issue =/
5) I wouldn't use any task killer. Check the active apps and uninstall any app that doesn't behave (keep only the ones you REALLY need that still do stuff in the background, like email etc, but not too many). Seems to work a zillion time better for battery life. Unfortunately, there doesn't seem to be a decent way to enforce such a policy.
Regular background tasks are not necessarily ever active. It just means they're frozen in the background and do nothing. As long as they do nothing it's fine, it's just faster to start them again (instant, in fact). The issue is really when they're activating every XX minutes while in the background.
6)Doesn't matter, the recent samsung phones such as the SGS2 have a HUGE internal memory compared to other phones, you'll never have space issues for that imo.
7)Install a kernel with CWM and then, boot in recovery and run a nandroid backup. It will create the backups on your sdcard. Copy them to your PC. Also, copy /efs using tools or manually..
You can restore using a CWM kernel later on and nandroid restore.
You can also use stuff like TitaniumBackup, but it's not nearly as thorough as nandroid backup (which is doing basically disk images, while Titanium and other such apps just copy app/settings)
8)Trollish subject. Some apps are superior on Android, some are superior on iOS. Heh SGS2's browser speed eats my IP4 for breakfast for example. If the same Android app doesnt have the feature of the iOS app, complain to the dev or find another app.
9) it's true it's like that, nothing you can do about it (technically, something could be done but that's probably not wise at all)
10) Use another music player, such as PowerAmp if you like. There's (many, many) other possibilities as well. It also let you boost the volume higher than the stock max volume (although I find stock to be loud enough)
11) Don't use KIES air to do that then ;-)
12) Likewise. There are apps like KIES air, you might want to try them btw. Make a little search, I dont have the name in mind, but they do exist, others will probably point them out
13) I do get a progress bar that moves, maybe a browser issue. Anyway, see point 12)

Cheers for the answers and help. I write the comments inline below.

Hopefully this will help you, at least in some areas (i numbered them in the order that you have used):
1) using developer mode at least (i prefer it as its faster and more compatible than samsung's stuff) you can mount/umount at will the card on the pc via the phone without unplugging
A: i did test this mode but it asked me to unplug the cable also, same thing for MTP. Dont you get that?
2) You may want to try Opera Mobile, it seems to do a very good job at this. I'd like to see this in the stock browser too, but hey, this is Android, you have the choice to change the browser if you like ;-)
A: As mentioned i already tested this. Opera does some things better and some things worse. For instance visiting one of my favorite sites like Engadget.com the whole page jump up and down when i zoom in a little. To be honest the stock + Opera feel very bad compared to iPhones browser. I hope Opera or Samsung improve on this area. This is the most used feature for me.
3) Well, same thing I guess. 2.3.4 may improve stability but the rest, I don't know, I wouldn't bet on it. I like Firefox quite a bit as well, but text wrapping is odd on it.
A: Lets hope so
4) Android issue =/
A:
5) I wouldn't use any task killer. Check the active apps and uninstall any app that doesn't behave (keep only the ones you REALLY need that still do stuff in the background, like email etc, but not too many). Seems to work a zillion time better for battery life. Unfortunately, there doesn't seem to be a decent way to enforce such a policy.
Regular background tasks are not necessarily ever active. It just means they're frozen in the background and do nothing. As long as they do nothing it's fine, it's just faster to start them again (instant, in fact). The issue is really when they're activating every XX minutes while in the background.
A: Yes true, i think Android just shows to much info for regular user. I have to see past the background tasks perhaps. Also some appz you can not remove like the hubs and such. Sure i can root and hack but i'm not so interested to do so just yet. Maybe when i'm a bit more user and understand Android better
6)Doesn't matter, the recent samsung phones such as the SGS2 have a HUGE internal memory compared to other phones, you'll never have space issues for that imo.
A: Actually i got over 12Gig of Appz on my iPhone so 16Gig (or actually 12Gig which is free) isnt all to much when you have navigator (3,5Gig) and games and blogs and such. But sure its enought for a time to come. The bottom line is Google must be tougher with the market otherwise the fragmentation will just grow.
7)Install a kernel with CWM and then, boot in recovery and run a nandroid backup. It will create the backups on your sdcard. Copy them to your PC. Also, copy /efs using tools or manually..
You can restore using a CWM kernel later on and nandroid restore.
You can also use stuff like TitaniumBackup, but it's not nearly as thorough as nandroid backup (which is doing basically disk images, while Titanium and other such apps just copy app/settings)
A: Thanks for the tips, i will write it down. As said i dont dare yet to mess with hacking but soon i was actually considering using the TitaniumB , hear its easy to use.
8)Trollish subject. Some apps are superior on Android, some are superior on iOS. Heh SGS2's browser speed eats my IP4 for breakfast for example. If the same Android app doesnt have the feature of the iOS app, complain to the dev or find another app.
A: I'm noob on what is there on the market so i'm sure there are many awesome apps on Android but when comparing the same app on Android vs iOS the Android was inferior. That was what i was comparing.
Another thing i dont really experience is the speed. To be honest i dont see such a huge speed difference when using my Wlan at home. But maybe you are right
9) it's true it's like that, nothing you can do about it (technically, something could be done but that's probably not wise at all)
A: I guess your right. On the other hand it could be possible a fw update could adjust some values for the current input, this could be a software limitation also i think. Lets hope
10) Use another music player, such as PowerAmp if you like. There's (many, many) other possibilities as well. It also let you boost the volume higher than the stock max volume (although I find stock to be loud enough)
A:Thanks for the tips will test this. Actually this is same thing as the copy/paste issue. I expect the behaviour to be the same no matter application (coming from iOS) but here it seems its application to application. This offer more freedom to developers for sure but it will also generate crapy software and result in a bad user experience. It would be so much better if there were a set of rules that all developers should follow on certain areas (this one is one such area).
11) Don't use KIES air to do that then ;-)
A: hehe true but this is the official way so i thought it should have been well tested and all
12) Likewise. There are apps like KIES air, you might want to try them btw.
Make a little search, I dont have the name in mind, but they do exist, others will probably point them out
A: Will do.
13) I do get a progress bar that moves, maybe a browser issue. Anyway, see point 12)
A: Strange, have to test again on IE which i hate, i use Firefox only. Also tested Safari on my mac.

Thanks again for your input mate. Back to play more with my GSII

Applications can also be installed on the external sd card.
Applications and I also believe their user data are backed up on google server. So if you factory reset the phone and sync with google, it will download all previous apps.
About the slow charging - are you on old firmware version or do you charge over USB?
Creating a folder through kies air is not possible, that is correct. To be honest I am happy that there is even an app which allows to copy media etc. over wifi, you know there are phones which don't have that, for example the iPhone.
All apps I am using are working fine. If an app is not stable it's developer's fault, not the phone.

Ios is from 2007.. android 09.. 1-2 years between them. just think how far android have gone the last year.. give it 2 years and then compare it to iphone 4 in it current state.. well yes i know android is older.. but the initial realse was around 08-09 and IOS june - 07.
and yes.. so far iphone fits those who just want it to work better.. that means ppl not that used to computers etc.
and currently i dont own an iphone but i got a first generation ipod touch.. and yes even that stoneage IOS thing does alot of things better then my S2..
bah but this iphone vs android is getting old its a subject that can go on forever and ever..
well ill stick with my laggy android.. well i've been told by my iphony friends that its laggy.. i just dont see it

Hi guys,
Any input, tips, tricks are welcome. I really appreciate your help.

Nice overview.
IMO S2 is the best phone on the market now. But due to appl's hype, n matter what hardware specs they release, the iphone will always be superior to ANY phone. They could release an iphone with 1st gen hardware, and it will still make more sales than sgs2.
But, slowly more and more ppl are moving towards androi, and apple are losing sales. they even copied bb and android in ios 5..

Also coming from an iPhone 4 to the GS2 I can safely say that I don't miss the iPhone at all which I thought I would.
Having owned a Nexus S in the past and feeling a bit bewildered as there was a lot of stuff within the OS which felt unpolished and unfinished and now 2.3.3 is like night and day for that and it feels much more like a complete OS to me.
@OP give it time there will be a lot of things you can do with your new phone which would require rooting on your iPhone 4
The world of apps and widgets and customization is at your finger tips so jump right in and enjoy
My phone is running ADW Launcher EX with 90% icon dock size, 5x5 grid for homescreen, transparent drawer and miui weather

The only thing you might miss is the app store and iTunes integration (if you use it), other than that the Galaxy S II has it beaten quite comfortably.

@zxz0O0:
OOH that is cool , i think some option about it but didnt think it was what i thought it was nice to have it confirmed. Then this is pretty much what Apple is adding into iOS now with the cloud thing. Pretty cool Android has it already. By the way why do people use program like TitaniumBackup when there is google sync ? is there any limitation to the cloud backup? will all games data, programs data, settings be backed up or just Android OS stuff?
About FW i use the latest i think KE7 i think its called but i read there is a new one coming out next week so hoping for better battery life.
And your last point is something we can debate about for a long time but my view is that if you dont have strict rules developers do what ever they want and can let their app go without update. On the other hand if Google enforce some guideline like having option to install to SD card developers must go by that or their application is removed from market. In the end users will benefit and the platform will grow. But this is my view alone.
@olyloh6696:
I dont think its just hype really. I mean we are comparing a year old phone to SGII here and they are pretty much head to head in most scenarios i tested. But i see your point and i do agree that Android has a charm about it. I love the moving background, i love the whole flexibility to do what you want with the interface. Specially SGII's support for codecs so i dont have to spend 2 day re-encoding all my movies etc. So there are definatley benefits with Android but iOS has the benefit to be easy and working perfectly with the functions it offers from the get go. I think its a matter of preference and more advanced users will move to Android (a bit like me).
@daleski75:
Yupp i think i just need to play with it more and get used to the eco system
I think i will harass Opera developers to fix the formatting thing on the webpages now
Thanks for your input guys, gonna go out and take a walk now, later.

There are also many other good browsers, xscope, miren and dolphin hd to name a few, they all have their own way to format the page and all are pretty good many have different options too for formatting and text wrapping (I believe the default samsung browser also has some options)
also I believe google sync doesnt save all app data (eg angry birds progress is not saved)

That is correct...Google Sync doesn't backup app data (like your Angry Birds scores). This is where Titanium Backup (commonly abbreviated to as TiBu) comes in. It "sort of" does cloud backup (via Dropbox), but its strength really shows when you start installing/changing/updating custom ROMs. Typically, it's used to backup your apps and their data to a folder on your SD card. I can also do some pretty advanced stuff that you probably wouldn't use much (if at all). In my view, the strength is it's ability to deal with batch jobs. For example, before installing a new ROM, I backup all user installed applications (non-protected ones, anyway) with only a couple clicks. Restoring is just as easy, provided you have the paid version (it allows for hands-off batch restore of your apps). Another cool feature it has is "freezing" apps. Say you root your phone and may want to clean some carrier crapware off of it, but aren't *totally* sure. You can freeze those apps...they stay installed and can be defrosted at any time, but they won't be available for use until you do.
Also, I agree with you that a lot of iOS apps are much better than their Android counterparts. I believe this is the case for one main reason: there are tons of people using Android and tons of people on iPhones...you can essentially count on one hand the number of iOS phones Apple has to support, and they are all sold by Apple. Now, look at the number of Android phones and devices and their individual specifications...that makes developing apps for Android pretty complicated. Devs have to take into account different CPUs, memory limitations, and the biggie--SCREEN DIFFERENCES! However, I like being able to run an app developed for a phone on my Honeycomb tablet. Yeah, it may be ugly (not necessarily), but it almost always works! I have a network tool I use that only shows up on about 1/6th the screen of my tab, but I don't care...it still does the job.
Don't forget another important aspect of the Android vs. Apple thing...Apple has control of their devices and their operating systems, and the cell phone carriers don't have control over when Apple releases an update. On the Android side, you have some manufacturers that are prompt with getting an update ready, and those who abandon their devices after they leave the store shelf. Not only that, but those who do release updates, and most do, have to deal with the likes of AT&T and Verizon and everyone else here in the US. Each company wants a ROM customized only for them, and sometimes the manufacturers actually have to pay the cell companies to push out updates. This is what causes the splintering of Android, but openness is what gives it its strengths.
As a general rule, I find that the more "techy" people like the Android OS, since you can customize it and tweak it like crazy. Those who aren't quite as savvy will probably like iOS more (there's less to screw up and they all look the same). Please don't flame me for saying that...it's just a general observation that has many exceptions.
Well that's my two cents. Maybe it will be helpful in some way? <*schrugs*>

Sent from my Inspire 4G using XDA Premium App

There is no practical comparison possible between the mentioned phones.

Appreciate the explanation brad, TB is a nice tool indeed
Just one point, In regard to customization i can pretty do anything also when i jailbreak the iphone which is even simpler then rooting Android and what all techies do anyway with their Android phones
But i agree Android has its charm with the more open eco system.
The 2 area i wish to have before it gets perfect is the browsing and more resolution for the big ass screen (4.3)

[Q] How to make MF3 snappier?

Well my S4 is running MF3, rooted and bloatware frozen... however sometimes it lags, even my S2 running Shostock 3.0.2 (based on 4.1.2) is way more snappier. So all you guys with MF3 what are you doing to make this crap MF3 worth the "S4 name" ?
Thanks.

I have been on a quest to see "lag" on S4 which I cannot say I have seen (or it is in places I am not paying attention to)
However I have been checking out some apps that state they make you device run like new or something towards those lines. maybe I can help you
#1 Get XPOSED FRAMEWORK from apps store (free) - this is like a gateway to some cooler fucntionality
#2 Get GREENIFY from apps store (free) - read instructions - do not greenify clocks or messaging apps or they wont work
--use common sense basically, I greenify all games, browsers....stuff that I start interaction with.
#3 Get WANAM XPOSED from apps store (free) - here you can adjust colors and a lot of functionality.
---one thing of interest is ENABLE BOOST MODE (enables benchmark boosting for CPU to achieve MAX power)
#4 Get Android Tuner (free/paid) - I paid for mine. However this app lets you tune every aspect of the OS, if you're a power linux guy you'll pick up on what it is doing.
---however this provides a feature called TRIM which keeps the drive/storage at top performance. Google "ssd trim" for details if you dont know what it is
Now I can use these apps *blindly* and force my phone to run slow, but if I disable them (back to stock settings) I seem to run just fine
A word of caution:
Throwing every "enhancement" feature from different 3rd party application on top of each other can have a negative effect.
*Ever run 2 decent antiviruses at the same time? They play tug-of-war with infected files and you lose performance

Thanks for those recommendations.. they look awesome will try one at a time except the XPOSED FRAMEWORK.. until a flashable image of MF3 is rolling, I'm trying to avoid messing with framework...
But well this is lag is kinda weird.. for example after using the browser or any other app for a bit of time then when press home button it lags to show the default screen and when it does the whole "desktop" is been redrawed of course this not always happen, sometimes it's very fast.
Also sometimes scrolling between the windows is very fast but sometimes very slow. And this lag is present when using several launchers, apex pro, nova or touchwiz, and i don't have much widgets running.. exactly the same as my galaxy s2 which can handle all this light usage without a problem..

Gee I dont experience any of those problems.
Scratch that - I do get desktop redrawn if I play a heavy game for a while. I do remember seeing it put back the weather and the icons. Nothing I would consider a showstopper nor can I make it happen on demand
I am using the default Samsung Touch Wizard and no other launcher
Good luck in your quest of the Lag Beast

*MY BOEFFLA SAMSUNG ONDEMAND PROFILE ON POST 2!!!!
Prologue & Intent
I have used AOSP/CM based roms exclusively since owning Android handsets, there are many benefits to this, especially on handsets that manufacturers simply abandon and leave in a poor state, this is thankfully not the case on our trusty Galaxy S3!
However, one of the bugbears of being in the alpha/beta test world that is CM/AOSP etc, its the many teething bugs that can hamper your usage of the device and to make things more irritating, the S3 has plenty of hardware revisions and proprietary software that makes obtaining a truly perfect experience tricky for the developer and the user to achieve!
For these reasons, like me, you might have decided to return to Samsung stock rom or one of the the excellent refined versions of stock by the likes of @_Sale_ or @qaraqumus (NeatRom 4.3 & QS 4.4.2 N7100 Port).
When you return, you are greeted by missing features, but also greeted with excellent camera, depending on your view more polished stock applications that you can keep or get rid of according to taste. Of course, the main thing you will start to experience is STABILITY and its quite addictive!
So this guide is work in progress, I only returned to stock based roms 3 weeks ago, I really wanted a good stable camera and I was to be fair a bit bored of being a nightlie flashaholic! If you have useful information that can be verified as useful then please contribute and lets help others realise that stock is not a dirty word!
I find that all of the missing features from customs roms can be replicated and there is no reason to think that you will be de-featured by returning to stock, nor are any of these things laborious or complicated!
How to get the missing features back that you loved in custom roms!
So you have gone back to stock!
a) You are enjoying the stability and you probably love having the stock camera back! Oooh, perfect burst mode and video record pause! yum yum!
b) You are sad, you miss quick panels, you miss pie, you hate the annoying battery alerts and camera low functionality on low battery power!
These are the sort of things I felt I could not live without, so with help from my XDA friends, I have found answers to all the stuff I wanted back! If there is is something missing that you want back, ask on this thread and lets see if we can discover more together!
1) How to get back functionality like no low battery alerts, using your camera properly when on low power, browser exit, system tweaks, battery icon location and style, quick settings layout, sound behavior, long back kill, etc etc!
1. Install Xposed Framework, go here and follow instructions: http://forum.xda-developers.com/xposed/xposed-installer-versions-changelog-t2714053
2. Install the most excellent apps you will ever install on your custom rom, Wanam Xposed, now you can configure everything I mention and more! : https://play.google.com/store/apps/details?id=ma.wanam.xposed&hl=en_GB
3.. Optional install Gravity Box for Xposed, for enabling a few features not included in the more compatible Wanam! Such as full screen lockscreen widgets and some additional hardware key functionality! Be careful ensure that you mirror any similar settings between Wanam and Gravity Box to ensure you have not cross fighting! [/url]
4. Boot Manager - Highlights what apps boot with your phone and allows you to stop them doing so!
5. Flat Style Bar Indicators - Lets you pick some nice looking wifi/mobile indicators for your status bar
6) Recent App Cleaner - Cleans out my recent apps when I turn my screen off and allows you to select apps that you want to keep open as well
7) Xad - Works like Adaway, stopping adverts where it can, its better than adaway as well
8) Xposed Additions - Allow excellent re-mapping of your hardware buttons!
9) XuiMod - Only use this change the system transitions when opening and closing apps, really nice
10) YouTube Adaway - Removes ads and suggestion pop ups in YouTube
11) Start feeling really happy about returning to stock!
How to stop battery drain!
Ok, this is annoying, but it is easy to sort out! there are some basics to observe and then some extra things you can do as well! Everything can be done safely and be reversable so you may experiment freely! Of course, it's a great idea to do a nandroid backup in case you make a mess of things, but if you follow this guide you will be fine and happy!
i) Get Greenify from the Playstore, run it, follow the instructions and limit the apps from waking your device up! On 4.3 roms I find it very useful, however on 4.4.2 I find it a lot less useful, in fact I don't use it at all on QS and I find that xposed Recent App Cleaner performs a better job. However for 4.3 users, stuff like Facebook etc will wake your phone up until the cows come home, but do not greenify apps that you want to be able to deliver on demand messages, like Whatsapp etc, obvious? UPDATE - If you are Pro user then use the Hibernate and Lock Feature to ensure your phone goes to sleep nicely!!!https://play.google.com/store/apps/details?id=com.oasisfeng.greenify&hl=en_GB
ii) Instal betterybatterystats, follow the xda thread to understand more about what you are doing and you will soon know which naughty apps that are waking up your device! You can then install apps such as Titanium Backup and freeze those apps, so that they no longer run and no longer drain your battery. If you decide you want an app back, then unfreeze it! It is as safe as that! https://play.google.com/store/apps/details?id=com.keramidas.TitaniumBackup&hl=en_GB
iii) Tryout Recent App Cleaner for ensuring apps a killed when your screen is off, seems to work better on QS/4.4.2 roms than greenify, read my post here : http://forum.xda-developers.com/showpost.php?p=58086117&postcount=112
Alternatively use RootAppDelete, i prefer this app, you simply click on system app, choose junior mode (pro mode will delete the app, which is fine if you know for sure you want an app gone forever! or at least untill you next flash an update rom back to your device, disabling is the safer and easier option!) which will then only freeze the apps (just like titanium) and you then tap the offending app and allow it to disable it. If you want one back, then tap the disabled icon and tap the app you want to bring back to life! https://play.google.com/store/apps/details?id=zsj.android.systemappremover&hl=en_GB
What system apps should I get rid of?
This depends on your usage and which revision of android/rom you are using, but for me all of the below were pointless battery draining ram using wastes of space or apps that have a better alternative that are more system resource friendly! If you are unsure, google search the name of the app and you will find results explaining what they were doing within the first page of results, i did!:
NOTE: Please make sure you research each app/service to ensure that your application will not be affected by freezing of any of the below, you can do this in google search or if you use Root App Delete you can press the info button to get an instant google search result!

AS I SAY, GOOGLE SEARCH NAME AND READ UP ABOUT WHAT THE APPS ABOVE DO BEFORE DISABLING THEM, BUT IF YOU WANT THEM BACK JUST UN-DISABLE! SO VERY SIMPLE!!!
Custom kernel sir?
Your stock kernel is good! Remember that!
The custom kernels are better if only if you have to have some of the features, like a desperate need to under or overclock your device, change led behavior and so fourth!
There are many to choose from and you will find them easily enough, I am sure you know of them! I use Boeffla and I have a stable gently overclocked profile you can get from my signature if you want an easy ride with great OC performance, stability and great battery results!
However, it's always best to stay on stock kernel whilst you make your system stable, once it is, then is the time to play with your kernel! I won't and nor will most other users want to help you if you don't follow that simple rule!

Trouble shooting
Correct Wiping procedure:
Forgot the correct procedure for wiping your phone when making a switch between rom variants? Just so you do know, when moving from Android revisions or even within the same android build number (i.e. 4.2.2 / 4.3 / 4.31 / 4.4.4 etc) IT IS IMPERATIVE that you Factory Wipe Data, Cache, Davlik and format System! Failure to do so can lead to odd performance or nasty bootloops! Thanks to @andrewwright for reminding me to remind you!
NOTES
I have not developed any of the apps or mods or guides that are linked to this guide, please pay respect to their respective authors and contributors directly on their forum threads.
I will endeavor to update this guide with new things I discover and learn from peoples contributions on this thread.
You always take responsibility for your device! The easy way to protect yourself is make a nandroid backup, back up your apps using titanium backup, freeze or disable your apps rather than uninstall them, don't do anything suggested on this thread unless you are either competent or willing to learn as you make mistakes!

When flashing roms:
To stop the likes of bootloop when swapping between aosp and custom tw sammy roms remember to format data and system in recovery FIRST then flash rom/gapps. factory reset isnt enough imo for a clean install. When returning with an odin flash if you have a bootloop go into recovery and "factory reset" and reboot the phone.
I see so many threads started about these bootloop problems when swapping between aosp and tw its a good idea to have this here imo.
Also for the total noobs out there...PIT FILES are a LAST resort! Dont mess with these till you understand what there for. If you still dont understand after reading about pit files....ASK SOMEONE. Dont just flash and hope for the best.
Great idea and a good guide. :thumbup:

I'll add a trouble shooting section and incorporate this, thanks for contributing!
I forgot that some people don't always know the mega basics!
And God, I hope people don't use pit files on this device! I made custom pit files for the s2, but that device needed them! I have threads for that work, but yes no need for people to play with that on our trusty phone!

I think gravitybox has more features than wanam. Like double tap notification bar to sleep.
probably you should include gravitybox modules. I'm using it. On archidroid.

Indeed, I use Gravity box also, I need a bit of both to get the system functionality I desire.
I will be updating the OP for Gravity box shortly, there are a few things to be cautious of according to some user reports, so I need to put a disclaimer to it. Cheers for contributing :good:

yeah. GB is not meant for samsung touchwhiz. wanam is designed for touchwhiz.
so far i dont have any issue.
the reason why i use GB is because
-double tap status bar to lock screen
-status bar icon can be changed to kitkat icons
-ram bar available for recents apps
if only wanam have these features then i would go for wanam.
currently having greenify and gravitybox in my xposed module.

It's very hard to differentiate between archi and neat, both as good as each other!
Mixing both modules no issues, but obviously make sure your settings between the two don't conflict otherwise you could have issues.

update, I should have mentioned that using version 2.7.6 of gravity box combined with Wannam is fine, the later versions do cause ui issues! I will be updating OP soon

Give the profile a try and find out. I find ondemand the most balanced performing governor, offering both performance and battery saving potential. However, upon my using my v3 profile for s couple of days, I have chose to alter my setting of swappiness from 60 to 40 and have altered the zram down to 160mb. The balancing of the profile is getting close to perfect and I hope to release a final version by next weekend!
Let me know how you get on if you choose to try

Yeah, I'm curious as well..i want to know if this update is going to be worth it

I did update to Nougat. My use is very limited but I find battery timing much improved and multi window is way better.

first of all - if you're satisfied with your device as it is don't update! It (unfortunately) doesn't get any better. They removed two important features - at least for me. There are no floating apps anymore - so if you want to use the small version of (for example) the google play music player while you're browsing you will have to use the splitscreen with dramatically decreased space for your browser left. So basically this means less convenience for you. The other thing is the (absolutely) useless "recent apps" view. In the past the whole screen was used by displaying the apps as tiles - now you only see them in the (for big tablet screens) useless card view.
Sorry - i always hate it when something really good just gets abandoned and replaced by something far inferior
I also found out, that manufacturers of 10"+ Tablets are encouraged to implement the native Android N freeform mode - so why has lenovo left this out of their update? I hope it gets back on the device with a later update.
P.S.: Android 7.0 CDD states that:
Device implementations with screen size xlarge SHOULD support freeform mode.
In the parlance of this CDD, there appear to be three levels of endorsement: SHOULD, STRONLY ENCOURAGED, and MUST. SHOULD is the weakest of the three, but it is still an endorsement.

First of all, updates are really important for android devices in general. And especially for manufacturers like Lenovo which is known to let their product outdated pretty early. Personally, I'm impressed this time they updated to Android N even before schedule, and I'm hoping they continue releasing updates not to let this amazing product die.
As for the features you talk about:
1) floating windows in freeform is natively supported in android N and just need to be enabled in developer options (one of the last entries under App category). You can install "Taskbar" app to launch all of your apps in window mode by using the native method, and resize them as you like by dragging on the bottom-right corner (which previously was not possible).
2) It is true that Task manager with tiles view was a more clean way to switch between apps on this device, but the needing of double-pressing the TAB button when alt-tabbing beween apps, always made it uneffective and uncomfortable to me. Now ALT-TAB switch between apps just flawlessly as in a standard computer. Hence, i'm really happy with that.
3) I find overall performance have gotten slightly better with the recent N update: i can notice that in the UI and in games too! other users on other threads are talking about a slightly better battery performance too, so it seems like they optimized the hardware support somehow.

Thanks for the suggestion of taskbar - i've already tried it before and imho it's just not that convenient as a rom included solution. Beside the fact that you would have to use an unnecessary extra app for a native android function, it's not really intuitive in it's handling - but i have to admit, that every user will see that different depending on their needs My question is just why lenovo hasn't implemented this standard feature in a neat and handy way?
Speaking of different user needs/requirements - i've personally never used the Alt-Tab combi on my tab. In my daily use i use it most of the time in tent mode without the keyboard.
As to the performance - i didn't really noticed a change here. But in my opinion it was already really snappy before the update so maybe i can't rate that improvement. Maybe the animations between app switches got nicer but it's possible that i deactivated them before the update by myself - so nevermind

Guys, can somebody upload Noughat update otapackage?
I do not have a device but i need this to borrow graphic drivers.

After update to Nougat, battery drain in idle status doesn`t happen anymore. After a day idle, it takes only like 1-2% of battery. At least it is worth to me.
