Hey all. I'm considering this phone as my first Android purchase because it's on a really good plan where I live. I've heard multiple, semi-contradictory reports of lag problems with this handset due to the TouchWiz 3.0 interface.
Quick questions:
How bad is it?
Does the fabled Launcherpro UI replacement app fix the lag?
Oh, and if it's not too much to ask, one further query:
Is there a way to backup pre-installed apps?
The telco I want to get this phone with has pre-installed a bunch of stuff that might be useful in tracking my usage etc. In the event of rooting and ROMing this thing, I may want to keep those apps and re-install them after flashing the ROM.
Thanks in advance
im in the same position as you.
the mention of slight lag keeps cropping up. This worries me. I will be coming from a HTC Desire. I am wanting speed improvements, not slow downs.
Can anyone advise?
Also - in preperation for my new galaxy, I installed Launcher Pro on my Desire to see what it is like. It is ok. A bit laggy tho (more so than stock). Then I tried the ADW Launcher (which doesnt get talked about as much coz presumebly it isnt as good). I found it very smooth and just as smooth as stock Sense. Therefore.. maybe you guys should be trying ADW launcher instead
I've used both launcherpro and touchwiz and the only time I've seen any lag with either was when the phone ran out of RAM(or below 60mb).
lagging might be solved by installing custom rom
I don't have the phone, though i've been following Paul (Modaco)
forum/twitter, he also had lag issued until he installed custom ROM
and did some changes in it.

See, this is exactly what I mean by contradictory. It must be that some of them have it and some don't. WTF?

That's good, but that doesn't really answer any of my questions all that much. Thanks anyway.
This phone is ultra fast, end of. it'll be even faster when it gets updated to access the full 512 megs of ram
compared to the nexus one i had for the past two weeks, the galaxy s has serious memory problems and is significantly slower than the nexus.
As described above, the device is lightning fast until the free memory drops below a certain point (60mb mentioned aboce seems to be about right).
At this point is becomes _very_ laggy, and the only way to get it back to normal is by killing tasks with a task killer app.
The way Android's memory model works, it should never be necessary to end applications manually. And with the nexus this was indeed never necessary.
On the samsung firmware however, garbage collection does not seem to work as it should. Maybe it expectes that there are 512mb RAM accessable (currently the galaxy's kernel only recognises 256). Or maybe it is something else. Anyway, something is currently broken. I'm on the JF3 firmware.

I installed Spare Parts and set Activity/Process management to aggressive, and I've not seen any lag yet (Also JF3 firmware). While it's not an ideal solution, I feel it's better than running a task killer as it doesn't make my phone unstable just because I forgot to put something on the ignore list.
@mickeko thank you, I will try that.
Update: Setting Activity/Process management to aggressive in Spare parts doesn't help much. It is still very laggy.
I really wonder why mickeko does not have the problem - maybe I have a faulty device?

I had quite severe lag problems at first. I tried some task managers and they only caused more issues for me. Then I made a full factory reset, it's my first android phone so I wanted to get rid of any weird things I might have caused during my testing (I messed things up alot til I understood what it's about ). After factory reset, I installed spare parts, set to aggressive, and things work fine. I still have some lag, but it's way less than before.
I don't want to install inofficial firmwares quite yet, so I hope Samsung hurries up with the official update which seems to have resolved the lag entirely.
The lag is not being caused by lack of RAM (the device does see 512MB or RAM by the way, not only 256MB as reported above).
Currently the way the device is setup, it is writing all DATA files to the internal storage and not to the NAND as it should. For some unknown reason the internal storage has slow access times which is causing the lag.
There is a hack on Modaco's website that allows you to have the device write DATA onto the NAND and that fixes all the slow down issue however it has a limitation of max 130MB usable space on the NAND.
Samsung can fix this in a firmware upgrade by partitioning the space better.

I never had any issues with apps opening slowly before and after doing the hack I didn't notice a huge increase in speed(it's still noticeable though). Maybe some of the devices have worse access times or something as they seemed very high for such a high-end device?
You can watch my video of application starting speeds:
http://www.youtube.com/watch?v=rAE_zKAtMvg
its launcher pro, MinFreeMem on max preset, and apps data is moved to NAND memory.
Just check the speed

I don't know much about the Android inner workings, but Android System Information states 326MB(?) RAM. Which implies that the OS sees less than 512MB RAM on my device.

Speechless.
Yes its fast now, but that speed obtained is only the same speed you get with the desire without any hacks. This phone should be faster, and one shouldn't have to root and hack it to obtain a speed only comparable to a HTC desire . It's not fair coz I want this phone badly but this lag issue is really putting me.of

But aren't there problems inherent with moving the apps data to NAND?
(I can't post the link because apparently the mods need to verify my account or something, but there's a thread in the dev forum titled "Fix for lag" that addresses this.)
Ah okay. Over at MoDaCo they're saying that it stuffs up when the NAND runs out of space (as the fix simply moves the folder for application settings to the NAND instead of the 'internal memory,' which is actually an SD card).

Yes there is one hidden thing here: If you have lots of heavy programs like some games, some navigation progs, google earth, you must keep those heavy programs in the old location. I did exactly this - moved to NAND everything except Google Earth, some Gameloft games and navigation. So now I have really fast phone, all my programs, and there is still plenty of space on NAND memory.
I just got iconia 2 weeks ago and its not refurbished however I feel it is slow web pages take 8 to 12 seconds to load sometime if I'm performing any task it is stuck for 6 to 9second no response n then it works fine. There is a lag usually for 5 to 7 second. Is that normal I didn't root my tablet didn't install a whole lot app yet I just little bummed due to the lag n slowness. Any thing you can suggest or share your experience.
Many thanks
I'm not a fan of the stock browser. It tends to lag and has rendering issues. You might want to try Opera Mobile. ( be careful not to download Opera Mini- it's intended for phones) I've been using it for a week or so and really like it. Better rendering, smoother scrolling, less crashing.
I use dolphin browser works good.
bad browsing experience
I have tried many of the web browsers on the market..
My experience is Some view some sites better then others. I use the stock browser for most sites.There is NO real solution to this issue.avoiding portal type websites. Such as yahoo.com helps. if you need content from there or similar sites YOU can d/load there app from the Marker.
Also try this.. Advanced task killer app .This tool should not be allowed to auto start and run in background. but can be used to diag. a rouge app.
Get Advanced task killer from the market..
try opening it from time to time and see what apps are actually sitting in the TRAY. if you see some apps that you installed and have not used since your last reboot. try killing them and see if this helps.. Use this Tool for one app at a time. If you find the app causing the sluggish internet. See if you can adjust settings on it . Maybe tell it to not START to not push notifications and so on..
NOT All apps play nice . you might just have one of them that decide to steal bandwidth on a constant basis.
Good luck and we all feel your frustrations.. I will point out runny task managers in the background is BAD IDEA. not all apps setting in the try are actually running Many are static and waiting for your input..

I don't experience the lag you are posting about. You may have a misbehaving app on your hands.
I too have experienced random sluggishness at times with the stock browser. Its especially bad on javascript-heavy sites. My bigger complaint, however, is the random typing issues I have, like goofy text selection and seemingly stuck shift states on the keyboard.
This appears to be a problem with the latest update. Beforehand, this lag simply was not there. Some sites (XDA Developers being one) lag with the banner ad at the top loading. This happens on almost EVERY vBulliten 4.x forum. I think a lot of us are hoping this issue will resolve with ICS, since it's doubtful Acer will do much more work with HC.
I will echo what the others have said.
When I first started messing around with my A500 I too noticed a small lag. My solution was to root my device and load a ROM from the ROM list:
http://www.acertabletforum.com/foru...-a500-501-rom-list-updated-29-jan-2012-a.html
Most of the ROMs work much better than the stock android that comes installed on the A500. Also once I had pretty much cached the sites I use the speed issue vanished.
The stock browser lags. Especially when you use your keyboard (there are some videos on youtube) other browsers does not have this lags.
Hello, I just installed the stock ICS on my Xoom, and I'm disapointed ...
As everybody was saying "the Xoom is now a whole new device", I was expecting so ...
There are good points with ICS :
- new functionalities like icons directories.
- gpu acceleration for a few 2D applications.
- a few websites are now smoother.
- typing texts in forums is now fast.
- a lot more available memory : around 512Mb instead of 400Mb in 3.2.1. EDIT : since a reboot of my Xoom, the available memory dropped down to 360Mb !!!
But I was expecting a lot more fluidity, smoothness, from the 2D applications of Android.
- the new market is more laggy than the one of honeycomb 3.2.1.
- some web pages are smoother now, but some other are slower !!!! XDA for exemple lags more than in 3.2.1 !!!
- the 2D GPU acceleration does not work for all applications : even when "force 2d acceleration" is selected, some applications become smooth, some other don't, even when they are the same kind of applications.
- stock web browser crashes more than in 3.2.1.
- on stock browser search string on some forums don't work anymore (try on XDA !), same problem with some dropdown menus which let the web page disappearing ...
- the new kill apps system in ICS does not really kill all apps. So we still need an app killer.
- the portrait mode is still laggy compared to the landscape mode.
- the available memory, when the Xoom has just been rebooted, vary between 510Mb and 360Mb ... !!! With absolutly no change in my Xoom configuration.
- When you force OFF the screen rotation in landscape mode, if you lock the Xoom and put it in portrait position, when you unlock the Xoom the display will be in portrait mode, and right after the Xoom will be unlocked it will go back to Landscape mode. This bug didn't exist in Honeycomb.
- the cursor to select text to copy seems more difficult to position than in Honeycomb.
- if you kill the stock browser with an app killer, when you relaunch the browser it will then open the last visited website, which is as expected. But if you kill the browser with the Android task killer, then the browser (when relaunched) will display nothing.
So I don't feel like I have a new device, some things are better, some worse.
As I am very concerned by the Android fluidity, ICS is a big step forward, but there are still some more steps to do, and I hope we will be able, one day, to see Android as fluid as an ipad on our Xoom ... But I guess I should stop dreaming.
Maybe you should trying running one of those custom ROMS and see if you see and
better performance or features..it's worth a shot

You may be right but I would expect Google to optimize more Android without the need of tuning a custom Rom to gain (maybe) a few more images per seconds ...

No.
Most of the stuttering is caused by apps which are written by developers who don't really understand Android,
Seriously.
Pay attention to which apps aren't responsive. Look at memory use, wake locks, watch for unnecessary services and background threads.
Eliminate apps one-by-one until stuttering in menus and the desktop stops. Don't run live wallpapers.
Factory reset. System settings from prior Android revisions can cause problems.
I have fixed many of my friends' Android devices when they blamed the device or OS for lag.
Stock 4.04 is quite responsive and fluid. If yours isn't, it's probably the apps you've installed or settings conflicts.
Change animation settings under development to none or at least down to .5 from 1.0.
Use a third party launcher and third party browser if unsatisfied with stock. We have choice...we can use it.
My Xoom is as smooth as butter...no lag or stutter at all.
I always choose the apps to install according to their fluidity. I know some apps are badly developped. I also have no apps running in background (that's why I choosed the stock ICS), always killing running apps before running a new one. I also don't use animated background.
I do my best to let my Xoom run as smooth as possible.

Have you changed your animation settings under Developer Options (in Settings Menu, toward the bottom) If you don't need animations, then change the settings to "none" it will make a difference.

Thanks for these advises but the problem for me is not the speed of the device but its fluidity. So changing the animation setting did change the speed of the way the menu are displayed but not the fluidity of the animations.
About the fird party launcher, I think it will not make it run smoother as it will run in the background and occupy memory.

Why, I don't know, but I have always found increased smoothness from launcher like ADWEX. As they say, "your mileage may vary." The configuration in my signature represents what I think is probably the best, smoothest and fastest combination I can find. I also have tons of apps and a pretty elaborate theme and still my Xoom is butter-smooth. It can be done.

Why kill the apps before running a new one? If you are choosing apps based on how well programmed they are that seems completely unnecessary.

Hi,
You didn't mention what apps you are running.
I'm running 4.0.4 stock rooted - and no issues in general. It got very laggy once after running for a week, but a reboot fixed it. Like any OS, very complex and not perfect - reboot once in a while.
I honestly don't find ICS to be very much different than HC (nor did I expect it to be). (ICS is what google wanted HC to be but ran out of time, so released HC)

Adw auncher makes for a much smoother home screen experiance than stock. Stock struggles with more than a couple of Widgets. Its a diferant experiance, but definatly faster.

I thought you took it as a personal attack because you said "stop using crappy apps", which to my point of view is agressive.
That's it. I'm sorry if your goal was not to be agressive.
You know, there are lots of fixes for any problems this device had at one time, but many require rooting and installing custom roms/kernels/recoveries and certain non-stock apps. I realize that some people like staying stock as much as possible...I don't. I want to get root immediately and start customizing. That's just me. Some people don't like to eat meat...I do. Some people can't imagine not driving everywhere...I've never owned a car. We're all different. But sometimes you just have to understand that your desire to stay all stock comes at a price. Lag exists. That's why custom roms exist...to eliminate lag, among other brilliant things.

I didnt have or notice any of the problems you had on stock ICS
I am running the following rom on my xoom atm and have had no issues
http://forum.xda-developers.com/showthread.php?t=1437358
Hi all,
I guess ever since getting the Nexus 7 when it came out, I've been trying to reduce lag. It has become as sort of project of mine. The last year, I have gone over lots of ROMs, kernels, tweaking tools, and tried lots of good (and very much bad) stuff.
So far, I've come quite far and I am quite happy with the way my Nexus 7 runs. The Nexus runs great in all other apps, really. Browsing is smooth and not comparable in any way to what I started out with. I have some Danish, poorly designed sites that are quite heavy, and I get no lag.
Apart from one thing - i get BAD lag when scrolling down a list which has images in it. I also get minor lag at other lists, but images makes it horrible. My two best examples are the play store (almost unusable) and gReader (slightly better with images off in lists, but hey, shouldn't have to be like that).
I've been googling loads and it seems very few people have the same problem? I've had this problem with all kinds of ROMs, kernels, tweaks, whatever really. I can have a crap setup with a million services running and a google now process gone haywire with cpu at 75 degrees celsius, yet the stutter is just the same in play store and greader (e.g.).
My current setup (but note, I've tried many with same result):
- Completely fresh install of recent CM10.1 nightly
- franco kernel (1.7GHz CPU, 700MHz GPU, 512Kb read-ahead, interactive, deadline, fsync off, gpu scaling off, wifi performance streaming)
- Almost all services disabled, including most of google's, meaning I have greenify running, a few under google services and android keyboard
- Sync is currently off
- Currents is not installed
- I've got fstrim installed and run that recently on all partitions
- I've got 9GB of 13-ish free at the moment
- Location sharing off
- Accessibility off
- No widgets, completely empty homescreen (I use Apex, not locked in memory)
I've been testing on a 100/100Mbit line fiber and 60/15Mbit LTE and identical experience.
I DO have Xposed installed atm, but after this fresh install (and many other similar times), I go straight to play store on a fresh install before installing anything. Same problem always there.
I had been using Trinity kernel for quite some time, at the time I adjusted read-ahead a lot, but in this situation a standard read-ahead actually means less lag for me. I guess it means more, small lags, actually, less noticeable.
I've been testing Seeder and similar apps recently, but get no particular difference with this problem.
When using the older version of Google Play, it is much more smooth, yet in the lists with apps it still stutters. Like 2-3 stutters a second, at times it hangs for a whole second, when scrolling down. It stutters each time and image is placed.
My experience: It seems the act of scrolling AND loading images doesn't work well in parallel.
I really hope someone can help me understand the problem, or, if so lucky, help me eradicate (or at least) reduce it.
Mkay, so it seems I am in a situation, where lagfix etc. doesn't alleviate the problem with very low random write speeds. I have done Forever Gone and various other things, but it just doesn't help. So, after googling a lot again, with inconclusive results:
What the feck is the conclusion on those low read speeds? I have plenty of space free...

The Play Store has always stuttered horribly when scrolling, as does Play Music. From my own observations, this is an issue with the implementation of rendering in these applications, rather than a lack of system performance. It is not isolated to the Nexus 7 either; it occurs within these applications on every Android device.
When you load the Play Store (or Play Music with album art) and begin to scroll, images are loaded when they come into view and unloaded once you move past them. I would surmise that the behaviour is intended to conserve RAM on less capable devices, however the consequence appears to be that this constant loading and unloading of images while scrolling results in stuttering. I have tested this hypothesis by comparing image-based applications (such as HTC Music) which do not implement the aforementioned function against those that do. The result is always that the former are completely smooth, while latter stutter incessantly.
Now that most new Android devices are shipping with 2GB of RAM, I do hope that Google will either remove this function or disable it on current devices (based on the brand/model the device identifies as).
Hi All
I have an SM-N900 (exynos variant) running 4.4.2 XXUDNB2.
I am usually never bothered about the RAM usage even if it shows very high value regularly. While typing this msg I checked and it was 2.37 out of 2.66. I trust android itself to do the necessary memory management !!!
What I have been seeing recently is this :
Dolphin is trying to load a page... maybe lots of pic nd all.... while doing this if I try to bring down the notification bar, ir does come down but gets stuck on the way.... similarly if I try to scroll the page it gets stuck while doing it.... essentially it is not at all smooth...
Now, if I just launch the task manager, clear some memory and retry, everything works smoothly...
The Note 3 is supposed to be a beast.... when the beast stutters in front of my friends its rather annoying/embarrassing at times !!!
Anyone seeing something similar ?

Well just remeber that your phone its like a pc, if your running several apps on the background the system will run of memory for other apps, its try android manage memory and all but if it doesnt have free memory to load up an app, it will close some to free ram and that will cause lag on the phone, my recomendation is to look on the running apps tab and check witch apps at runing and close/froze the ones that u dont use to clear up some ram, im usually at 600 free ram all the time, if i clear ram i get almost 1gb free. so you should check what apps are messing with you.
