Is something wrong with my phone? My Quadrant scores are NO where NEAR where they should be. I just got a whopping 872 I avg 900-1000. I know it might not matter, and that those scores can be manipulated. But a few have suggested this might actually indicate that my phone is messed up and if so – I want to get another one from Sprint.
Basics – I am rooted, custom rom (myn’s), stock htc10 kernel. I don’t know what other information is need to get help with this. I have tried running Q scores as soon as I do a wipe cache/dalvik thinking maybe it’s just slow after that stuff clogs it up. Same result. I have tried moving as much stuff off my sd card and now leave about 1.5 available ( I’ve slimmed my music down as much as I’m willing to do . I’ve tried running the Q score with the kernel set to performance, etc. I saw 1250-1350 one time, but I was using a kernel that was so unstable on my phone I had to ditch it pretty fast (multiple reboots, severe lag, etc).
I also wonder if there is something wrong with my phone because it does not seem to be able to handle anything other than the stock kernel very well. The phone completely spazzzes out with almost every kernel I have tried except for two. I am happy with the stock and have no complaints about battery life. I use the phone when I want and how I want and easily go 24hrs without having to charge. But the fact that only stock and 2 other kernels (king’11 and netarchys) are stable makes me wonder….
If anyone has any suggestions, opinion, thoughts, etc I would appreciate. I have searched and not seen this specific issue addressed.
If this helps, when I check my Running Services, this is what I see and this list varies very little.
Blik Calendar Widget
Y5 Battery Saver
More Icons Widget

Def sounds sluggy.
My recommendation would unfortunately be to start from scratch. Backup only needed apps that you may not be able to download from the market and completely wipe, flash a stock OTA root ROM, completely wipe again, and flash whatever ROM you like after that.
I know it sounds like a huge PITA, but it should definitely help out.
I had a similar situation once, and this did the trick.
Ugh. Ok. I can try that. I did a full wipe/factory reset less than 2 weeks ago. I use Titanium so getting it all back up is not bad. I also sync to AppBrain so at least if I start with a clean slate I would know what Apps I did have.
Thanks for the help and suggestion.
to eliminate as many variables as possible, i'd do a nand backup, install your ROM of choice with no additional apps except the ones you use to benchmark and perform your tests. give it an hour or so after you flash to let the phone settle down (sync, etc.). you may have apps may be hogging resources or be running in the background (i.e. y5, antivirus) which will effect your tests. report back.
I will try that way first
Yes - antivirus and Y5 are always running in the background. Always.
ha - maybe I'll freeze most of the apps I listed as Running Services, wipe cache/dalvik, reboot and THEN see what I get. But I'm not ever going to realically run my phone without Y5, Handscent, UltraKeyboard, antivirus, etc. I could probably get rid of the More Icons widget now that I have Apps Organizer, but I really really like having one, 1/3 page widget with 8 icones that have ALL my apps organized.
Does your phone seem slow? That is what I would base the speed of my phone on not some q-score. What if you never ran the test would you be concerned.?.?
I would try this http://forum.xda-developers.com/showthread.php?t=836728 after your nand backup. That has the latest ota, kernel and you would not loose root.
I'll have time on Sunday to try some of the suggestions. Thanks again for the help, I really do appreciate it. I was with a friend this evening, his Evo is rooted and running Myn's rls3 just like mine. He scored around 1300.
And no - my phone doesn't seem slow to me at all. But I've also not used another to know how it might "feel" if there is a difference. I more curious than anything - I tend to research things to death just so I'll know. And I find it curious that my phone is both low on Q scores and can't handle many kernels without it spazzing out.
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!

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.

because quadrant doesn't mean **** in the real world, i score 2300 but thats with the 1.4 oc.
Give miren a try, tbh its the best
This issue actually started before I updated to 4.4.4. I am currently on 5.02.
I have the WiFi version of the 2012 Nexus 7. I am running the stock Rom, and am rooted (using Wug).
I have several issues with this tablet, but by far the worst is it runs VERY slowly, sometimes taking 15-20 seconds or more to respond to my input.
I have tried doing a factory reset. The problem with that is that the tablet responded better for a day or so, but as soon as I set up my account it began downloading all my apps, making it impossible to determine whether one or more of them is responsible.
I have tried going into developer Options and checking the "Don't keep activities" option. That had no effect.
It's especially maddening when I'm trying to view web pages (using Chrome) and a page takes f o r e v e r to load. Then all those javascript ads that pop up just as the page finally loads (I tried deselecting that as well, but then I can't view slide shows, videos, and user comments on web sites).
It's also fun to click on a link, only to have the page jump right at that instant, resulting in the click hitting an unintended link!
At this point I am out of ideas, other than buying a different tablet, which I can't do right now due to financial reasons.
So my questions:
How do I troubleshoot the speed/lag issue?
How do I prevent my apps automatically installing themselves after a factory reset so I can install them one by one in an attempt to determine whether it's one or two apps causing this?
Is there a pop up blocker available for Chrome (or an alternate browser) to both block, or allow on a case by case basis those dang Javascript ads?
Thanks everyone.

2 of these are easy, the other may take more work.
To prevent the apps from automatically reinstalling, open the play store as soon as the tablet boots up, go to my apps > installed, and click Stop. Then go to Settings in play store, and change auto-update apps option to "Do not update".
There's many adblockers out there, if you're rooted then you shouldn't have a problem installing them. I use AdAway and it works fine, Adblock plus is also popular. Just download the .apk for one you want to use and install it, run the app, then reboot, profit.
As for lag, though it's possible you have an app causing you some issues, this older device is also pretty well known for having a big problem with declining i/o performance over time, and this is more likely the culprit. But any apps that constantly run in the background can exaggerate this further, especially since we also only have 1GB of RAM on this device.
As you mentioned, a factory reset can sometimes help with degrading performance, but it will just degrade over time again through regular use (or as soon as a bunch of apps are immediately restored). This can sometimes be mitigated to a point by using fstrim, but this is not the final solution for everyone.
For me, converting to F2FS format helped with this a lot, it actually felt faster than when it was brand new initially. But it takes some extra work to make the conversion, especially the first time (you have to format your partitions, losing all data in the process, so EVERYTHING you want to keep has to first be backed up elsewhere then restored after conversion). You'll also need to install an F2FS compatible kernel or ROM. Do your research before jumping in if you go this route, and backup your data!
Thanks Prismatic.
I've seen a few posts from people complaining about the slowness of the OG Nexus. Since hardware like cpu's and Ram don't actually slow down (to my knowledge at least), I assume it's usually due to the larger size of newer apps? Like a Windows thing where a version seemingly becomes slower after several years because hardware requirements get more demanding?
But has Chrome for Android really gotten that much larger over these years to cause our little tablets to slow so much? I'm almost at the point where I use my phone (HTC One) more than my tablet for looking things up and browsing.
As far as changing file systems, I'll have to look into whether the community overwhelmingly agrees that the speed gain is worth such a drastic measure. Thanks for the input.

Chrome has been a problem (along with Facebook) for my 2012 for a long time. When I did the 5.0.2 upgrade I did a factory reset afterwards about did not let it reinstall apps. I installed some fresh from the Play Store that were essential (none that run continuously) one by one. I replaced Chrome as the default with UC Browser which has Facebook Fast integrated (does FB notifications running in background) and all was like new. The only defect is that you don't have a "share to FB" in other apps. Haven't tried FB Messenger yet either. Beside the system/Google and cloud apps running in the background the major hits are Amazon Kindle and my password manager (50 and 35 MB). UCB (w/FF) are only 7.3 MB. Leaves about 500 free ram.

BTW I only keep about a half dozen apps in "Recent Apps" and clear some out when it starts to lag a bit. The 2012 is not up to L's multitasking as L puts each tab or instance of an app there. Open a bunch of tabs in Chrome and you'll see what I mean.
I may try that myself. I already uninstalled FB (I've been suspecting it was a resource hog for a long time now).
I've been out of the loop for over a year though, what is "L"?

Let me guess: 16GB version? Those models used really crappy emmc that had a flash firmware bug where IO would get really slow once you hit 2-3 GB free space left on the device. If you're in that position, try freeing up space until you have 3-4GB free. It'll probably speed up again.

You are correct that I have the 16Gb version, but under storage it currently says, 8.5Gb free.
XDA Mobile App
Encrypted? If so, it wouldn't matter how much space you have free because as soon as the full-disk encryption operation completed, the internal map in the flash controller that keeps track of free blocks would think that there was no space left on the device (even though the OS and the file system would obviously report otherwise) and the only way to reset it once it gets to that point would be to reformat the file system (ex. Factory reset) which forces the flash controller to clear its internal map and start from scratch.
Either way, if your tablet is not encrypted and you're rooted, you could try to download the LagFix program from the Play Store and have it run fstrim, which would sync up the internal map of the flash controller with the current locations of free blocks of flash memory so the device doesn't keep slowing down trying to manually probe for free blocks every single damn time it needs to do a write operation. You may have to do it every once in a while as that internal map slowly fills up again though (the pro version lets you set a schedule). Theoretically, from Android 4.3 and onward, it's built into the OS and the the OS is supposed to be able to do it automatically based on certain conditions (ex. Idle for a certain amount of time, plugged in or 80%+ battery on a certain schedule), but I found that sometimes it needed to be done more often and it's always nice to be able to run the command manually if needed, although to be blunt, there's no reason why the end user should have to resort to this in the first place. That said, I don't know if LagFix will work on Lollipop (never tried; no longer have a rooted 16gb N7 due to a replacement logic board but a busted USB port so I can't unlock my bootloader to re-root the new board) and the program looks like it hasn't been updated since 2013. One way to find out, though and that'd be to try it.
Switching to F2FS as the file system rather than ext4 might help as well (I really wish I could re-root my device to try it for myself). The speed increases over other file systems when using it on flash memory come from letting the flash controller deal with the disk I/O rather than having the OS schedule things. When you look at the bug and what causes it, it could be the communication between the OS and the flash controller that's the culprit. So using a file system that cuts out the middle man and makes the controller deal with scheduling all the I/O might mitigate the problem (after all, the flash controller works fine when there's lots of free space, it's only when it fills up to less than 3gb of space that the flash controller's algorithm to sync what the file system advertises as free blocks with its own internal map starts to screw up).
I am not encrypted. I will try this LagFix app and report back, hopefully in next day or two. Do you recommend another factory reset first? Is been about three months.
XDA Mobile App
If you want, although I'd try LagFix first to see if that's all you need. If you do go through the wipe, run LagFix every so often to sync things up (assuming it works for you or on Lollipop in the first place).
OK, lagfix does NOT work on lollipop. It gives an error. When I can find the time maybe I'll try to convert to F2FS. Or else when I can find the money, try a new tablet.

Question: When you wiped the device previously, how did you do it? If you're using TWRP and use the Advanced options under format to manually wipe /data and internal storage, it'll just use the rm command to delete the files which won't reset the controller's internal map. You need to use the factory wipe option, which will use the mkfs.ext4 commamnd to format the partition (which is what you want). If you've been doing it the wrong way, then that might explain why you're still getting the lag despite having a lot of space still free.
Also, the built-in trim functionality (supposedly) only triggers when the tablet is plugged in or at 70 or 80% battery *and* has been idle for 2-3 hours so if you use the tablet a lot or keep it powered off when not in use, there's a chance that the automated task won't run (and since LagFix doesn't work in Lollipop until the Dev updates it to be compatible, then there's currently no way to manually trigger it). So if you haven't already, try leaving it in powered on and plugged into the wall outlet overnight while you sleep and see if it's better in the morning. Might be worth a shot if all else fails.
Thanks. Yeah, I always leave it plugged in over night to make sure it's ready the next day.
I probably did do a factory wipe, but I'm not certain. Guess I'll try that again eventually.
XDA Mobile App
Cool. Well, if all else fails, there's one last trick to try, which is to zero fill all the empty spaces on the drive to tell the controller that the empty space is indeed empty when it hits the "start probing the file system for empty blocks to perform the write operation" part of its I/O algorithm. You can do that yourself on the command line by using dd to create a giant empty file until the drive is filled up, syncing the file buffers and then deleting the empty file, and then sync the file buffers one last time. There's also an app that can do it automatically, which is just a GUI that calls dd, rm, sync, rm and sync in the background. I forget the name, but it's in the store and I think it has "secure" as part of its name.
I had moderate success with that method as things would speed up again once done, but would slow up again over time as the drive was used. Formatting the partition is preferable because it saves on write operations and thus, wear and tear on the flash drive but the downside is that you lose all your data. And zero-fill was the preferred method outside of re-formatting the partition until someone figured out the fstrim trick. You might be able to run the fstrim command from the command line if you're rooted since LagFix doesn't work anymore on Lollipop, but I forgot what the command line arguments are. Google could probably help with that.
So still a few more things to try before giving up. But I wonder if F2FS would work better. Let us know if you ultimately go that route.
You can run the trim commands from terminal. But I found increasing the minimum clock helped.

This issue actually started before I updated to 4.4.4. I am currently on 5.02.

WOW same here, I updated from kitkat to 5.02 today and my god, this is TERRIBLE!!!
I keep rebooting in hope that SOMETHING will be better. I know this is an old tablet but I have a good mind to call Google tech support and complain about this abysmal ROM.
I did not do a wipe, just upgraded as you'd imagine that would be all one needs to do, it is a factory upgrade after all...
Some apps take forever to boot and then are inoperable because they can take a minute to respond to a touch (facebook seems the worst)
Others are very laggy but useable (like a cheap phone from 5 years ago).
I guess I have to try a factory reset/wipe.
So just to update: I have been wiping the cache partition about every five days. It lasts about two to three days. I plan on waiting until I have money to get a different tablet before getting a different ROM, or converting to the newer file system (though that will probably be some time from now). In its current condition I can't even give this thing away!

Same deal here. When new the Nexus 7 performs great. I have a 2012 8 gb version primarily for platform testing. The interface is so slow now I've given up and just use my phone. The keyboard takes forever to show up. When you first load an app it takes forever and switching between apps takes just as long. The last Nexus and Asus mobile device I will buy for a good while. At least I can still use it to test an app and know that the app will run on a crappy performing device.
Nexus 7 2012 (8gb)
Android 5.1.1
I've done factory resets and it doesn't really help, maybe for a few minutes and then back to the slow clunker. Even after the reset the keyboard is slow as snot to show up.
Just to update, I ended up using Wug's Nexus Root Toolkit to push 5.1 to my Nexus, then I did a factory reset. It had already downloaded 5.1 from Google, but I was desperate.
I had already given up and bought a Samsung Galaxy S 8.1 by then. It's now much faster. Because I bought the Samsung, I'm not using the Nexus very much, so I can't say for certain I cured it. It's worth a try however.
Signature edited to appease the OCD's
I would suggest installing Chroma 22/6/2015. It's very good since Android 5.1.1 fixes some memory leaks over 5.0.2 ^^ It runs perfectly P.S I wanted to sell or blow up my nexus with other roms so it's worth giving it a try ^^ I'd suggest wiping internal storage too after installation so you have a fresher feel ^^
Plz do it :3 You'll not regret it! The UI is pretty coolio too!
Hi all. I recently purchased a unlocked 16GB Samsung Galaxy i9000 because of the sound quality, expecting it to make it my main phone for daily use.
I've tried all CM and CM-based roms for it, expecting to keep it up to date. Developers have made a great work porting the roms and I can do nothing but praise what have they done.
But it's an old phone meant for apps of years ago, and now it's time to retire it.
I install facebook lite, tweetcaster, spotify and waze, and these are apps that create a zillion files for caching purposes and when I open them they take ages to load and more than desired, hang the phone.
512MB of ram and what I think is the speed of internal eMMC (moviNAND or whatever) are the reasons of this.
I tried different filesystems tuning their features but no. It's a hardware issue and this is what it is. WYSIWYG.
My brother has a Sony Z2 and this guy makes app fly. Not only more RAM and better processor, but a faster internal speed make the things happen as they should be.
So... bye, bye. SGS. You won't believe it, but I'm back to my HTC Chacha until I find a new phone that keeps up to what I need.
Good luck !
Hey
I think you should give a try to cm11. The latest beta from the website is amazing
Here you go : http://www.cmxlog.com/11/galaxysmtd/#cm-11-20160320-NIGHTLY-galaxysmtd.zip
I never had this speed even on gingerbread.
Tried omni but it was too slow and not enough ram to handle it, my phone was warmer.
Give it a last try. And flash nano or pico arm version of gaaps if you need it.
Link : http://opengapps.org (make sure using arm;4.4; and then select nano or pico)
Seems like without the phone is more fast but nowadays everyone need google just for some applications or restore contacts, i am wrong ?
The only downside of this rom is the battery..
You have to try to disable services from google play services (keep it awake : off and wake : off, and disable the "ok" google now in options of Google.
Plus disable the system service to keep it awake (yes, turn it off). Everything must be done in parameters>privacy>3 dots>show system app except for google now.
Now I can easily read webpages with my galaxy s, or listen to webs radio using applications, sms, call, it's fast as hell !!! Also use Waze but it's slow on start, this device handle it at his best).
And trust me when i say i'd never had this speed.
Was coming from a old mackay rom (thx for his job) didn't used the phone again till now, and believe me this is incredible.
Seems like kk is the last good version that can be done on galaxy s without freezes/and having enough ram :good:
Hope it helps

I just installed CM9.1 ICS and seems pretty fast even if I didn't used the phone very much, is the 11 faster?
Honestly i can't compare i never tried.
Is the browser fine ? And do you get some little lags after 2-3 apps in background ?
Thanks. As I wrote, I tested many roms. Yes, CM11 works wonders, but battery drain is huge. Having the phone on the hand while screen is on and seeing after 10 minutes that 10%-15% is gone...
Yes, with no gapps (I don't use them) and freshly installed, it works wonders, but when installed, the mentioned apps slows down the thing a lot.
Selled it today to someone that wanted nothing but whatsapp.

I ask because I'm always on the hunt for my perfect ROM and I have yet to find it.
My perfect ROM would contain only what was needed to boot the phone, connect to the network and connect to wifi, and it would contain a good phone app as well. Nothing else, the bare minimum.
I don't need an SMS app, I use PulseSMS and I like it a lot.
I don't need an email app, I use Nine Mail.
I don't need a music player or an equalizer, I don't listen to music on my phone.
I don't need a browser, I use Chrome.
Everything else I do need, Contacts, Calendar, Camera, Clock etc etc, can be installed from the Play Store.
Yes, I know all about the ways to uninstall apps. The problem is if the ROM I am using upgrades, all of the apps I uninstalled come back so I have to uninstall them again.
Yes, I know how to disable apps I don't want. Several reasons why that doesn't satisfy me.
First, some ROMs include apps that can't be disabled. So if the SMS app can't be disabled and I install Pulse, now I've got two SMS apps on my phone which is a waste of space.
Second, even if the unwanted apps can be disabled, they are still there. Still taking up space that can be used by things I do want.
Yes, I know I can build my own custom ROM. I've tried it and I don't understand the process well enough to debug the myriad of problems I always run into.
Yes, I have a bare minimum approach to things like this. But consider how small the download would be for a ROM like this.
So far, Slim ROM comes the closest to what I want, but even that includes some apps I'd prefer not be included. Also, I'm not sure how active Slim is these days. There hasn't been a lot of activity over the last few months.
So, that's my perfect ROM. Active and minimal.
How about you?
What type of platform/base are you looking for? In terms of bare mobility versus stock? I can take most ROMs strip them down to the point of being functional is easy. The hard part is keeping up with kernel and platform changes.
You might want to try Velocity Rom... it's almost as bare minimum as possible although you get a messaging app(you can't avoid that since all roms out here will definitely have a messaging app and it's fine). On top of this you get all the customizations. Though I'm not currently on it, but you will like it's bareness:silly:
Just Google for Velocity rom.
Cheers!

The base doesn't matter much, as long as it works. Maybe aosp, if such a thing is possible.
For the platform, the latest and greatest, of course.

Yes, I tried Velocity. It looks good but the SMS app can't be disabled. At least in the one I tried. At least with Slim it can be.
