Lag redraw on home screen - Samsung Galaxy Nexus

So I thought I'd bring this up and see if others are having the same issue as me. I purchased a Google play galaxy nexus and it recently updated to 4.1.1. I've noticed that since the update there is often some home screen redraw where the icons and launcher reloads on the home screen. I thought maybe it was the flip board app doing that since after I hit home after using it it would redraw the home screen. I've uninstalled but I got another redraw. I have plenty of internal memory. I've also gone into setting, developer settings and allowed only a 4 processes at a time thinking my RSM was being used up. How much ram is available ? Is there a way to figure that out?. Anyone else getting this?. Btw I'm completely stock and not rooted. Never been rooted and no unlocked boot loader. I will not root and flash Roms. Any ideas.

Found out I have 218 mb free and used around 450 something. For some reason maps processes are running in the background. Anyone recommend any settings or cache apps

When I press home my apps dissapear for a while

This happens a lot. Is this normal? If so is it a ram issue with the phone? And is there anyway to improve that?
I haven't got around to permanently rooting my phone I have the stock OTA but if it can fix this somehow I will definitely do it. Thanks in advance

You mean when you press home your homescreen reloads and apps reappear in a few seconds? Seems normal as of now. Running CM6.1.0RC1 still happens. Haven't found anything to really fix this.
Root and overclock problem solved. Zoom zoom

Same here, when I overclock more than 1 g that problem seems to go away.
I used to have the same problem with the good old G1. Back then I thought it was because if not enough memory. Enabling "lock screen in memory" in launcherPro or AWD solved the problem. If you are not using them, run to the market and download one if them. No root needed

Yea I press the home button and my apps are invisible I guess and it last like 5 to 10 seconds and it happens a lot like every other time I press home.
Well in that case ill try to get around to rooting it.
launcherpro seemed to fix the problem so far thanks.

I'm overclocked at 1.1 and still always experience this problem. Also locked home app in memory in CM settings as well as enabled system persistent and still no fix for me. It's not bad, homescreen always came back. On my myTouch when this happened they'd sometimes just stay gone.

My myTouch stopped as soon as I enabled system persistent and enabled compcache.
Setting my mhz to the lowest number in the screen off setcpu profile seemed to take care of that problem for me, but it only happend to me when I was overclock to 1400+ and only when i unlocked the screen.

[Q] Wallpaper scaling down randomly

Hi all,
Sometimes when I'm in an app and go back to the home screen, my wallpaper will scale down and show black bars up top and at the bottom (letterbox). Only fix is restarting. Even re applying the wallpaper doesn't help.
Any one else having this issue? Running the 4.0.4 ROM from the dev section.
Sent from my Galaxy Nexus using xda premium
Bump.
Just happened again after opening exDialer and going back to home.
Would love it if somebody could give me a pointer as to how to troubleshoot this. There are no wallpaper setting apps installed, FYI. Just the stock gallery.
Here's a screenshot of before and after. You'll notice the top and bottom letterboxes in the after pic. Just randomly happens, and only a restart fixes it.
I've never experienced this issue. Maybe its an ADW Launcher bug? Does this happen with the stock launcher?
Never had the stock launcher on long enough to tell, hah. Guess I'll try it for a day.

It's an adw ex thing. I installed apex launcher beta, which is a lot better and faster on ics imo, and the issue went away.

Bumping this, as I recently started having the same issue on Nova Launcher.Its doing this on every ROM I try. Any ideas?

Holy memory leak Batman!!

My phone had been running pretty great for 14 days now without incident (in the past I was getting reboots) but then a few days ago I started getting more and more frequent launcher restarts. I checked running apps and memory was at 120MB. I restarted and with the same exact apps/services running I had 322MB. So the question becomes where the hell did the 200MB go? Seems like a memory leak to me but have no clue what could have caused it. An update can't come soon enough for this otherwise fantastic phone.

just the way it is. I experience the same thing and i show around 130 mb of free ram all the time. I just let the phone do its thing though. I'll reboot once every 2 weeks or so. I dont think your free ram level is abnormal, i see it all the time. Yes a reboot increases it to 300 mb. But it shortly goes back down. I would ignore it.
I will notice that when i get down to around 100 mb free, i'll just go about my browsing or whatever and half hour later it corrected itself showing 190 mb free, all identical apps still running.
Its the mystery of linus. Ram is shared in ways that make it extremely difficult to tally free ram. Thats why i just ignore it. And yes i get launcher closes, along with overly aggressive task killing by the OS. I personally think its a bug google may fix.

Galaxy Nexus keeps apps in memory, it never has 'a lot of free memory' if it has been running for a while. It clears memory when an application needs it and that's it. There's no 'memory leak' of that sort in Android, but there might be something off with one of those applications that might end up hijacking so much memory.
As for launcher restarts, this has never happened to me and I'm thinking that some application, that you have running, causes this.

I don't care how much memory is free. I just can't stand the launcher restarts which are directly related to low memory because the system has to dump the launcher process from ram to make space for other processes. I've seen it on many phones. Apart from the launcher restarts the phone is fine.

Well without reboot most I've had my phone up is 6 days. My free memory was just over 300MB so I'd almost think it's some app you are running too because why am I not seeing any leak? Are you running Nova Prime or just the freebie?
We have had a similar thread before. OP in there was amazed that some of us had 300+mb free and he had 120. Turns out it android 4.0.1 was the culprit. Are you still stock or 4.0.1?

I'm on 4.0.2 stock. My guess is .3 and later fix the issue but I'm too lazy to wipe the phone and flash a rom. I'll have to wait, it just sucks that the update is taking so long to push

In the world of real operating systems, free memory is wasted memory. Why bother releasing memory if there's nothing to replace it with?
If you are low on memory it's a good thing in Android, because that means that many apps are pre loaded in the RAM so they can start quicker.

Thank you. There's a definite memory leak. Its been a day of hard use after reboot but my memory is still at times 300mb free or more. Before I rebooted it never got higher than 120. I'm hoping the app that caused it has been fixed with all the recent updates.

Right now I have anywhere between 60MB and 100MB of RAM free and zero launcher redraws. So your phone being 'low' on ram isn't what your problem is.

What are you using to see free memory? Its reported differently in different places. Go to settings Apps and Running. What does it say there? I have 300MB but it shows 100 or less in many apps. The number in the place I told you to look is how much memory is usable for user programs since it removes the kernel and running services. THIS number for me was 120MB which means all apps only had 120MB to run that weren't services. So what does yours say?

From settings > apps > running now I have between 100 and 150.

wow. And no launcher restarts? That's interesting? What rom are you on? I'm stock 4.0.2.
Sent from my Galaxy Nexus using Tapatalk
The memory is a red herring. If your launcher is restarting frequently there's something going on, but memory may not be a part of it. Perhaps it's a misplaced pointer reference or a widget that's causing the launcher to reload to resync or maybe it really is a memory problem. Either way, focusing on the memory probably won't get you any closer to the root of the issue but uninstalling suspect apps or widgets may.

Nope, works fine for me.
Nope. Not very. Just a bit laggy.
I see that UI on 4.2 is not so fast as it was on 4.1.2, but some apps (e.g. chrome) works a bit faster.
So, yep - I'm happy with the update.

People who aren't having speed issues: Can you test a couple of scenarios I've noticed in particular?
1) In the new gmail: tap on the account switching area at the top. This loads far slower for me with the new app
2) Put your phone to sleep or wake it up. Sleep/wake seems quite a bit less responsive in 4.2 on both of the stock phones I've tested.

Disable all animations in developers options and screen off animation will be less noticeable.

i made i wipe cache and now is working fine. thanks a lot
No. 4.2 is just as fast as 4.1.2 on my GNex... which was fast whether I use the stock UI or Apex Launcher. Granted there is an initial sluggishness during the initial boot from services loading in the background... but after that my GNex is smooth and fast.
Those of you experiencing slow speeds: Try flashing the factory image from Google. I had one app that didn't work properly and a flash to factory stock and re-root fixed the problem. It's possible you have an app running in the background eating up resources too.
I understand these threads and posts must be annoying to those who aren't having issues, but to people like me, who OTAed a bone stock phone and are left with a less-than-satisfactory experience, it is equally frustrating. Especially considering how many improvements were made with 4.1-4.1.2, which have now been rendered moot.
I guess my only recourse is to wipe and flash stock, but because I'm not rooted and don't have any backups, it'll be fun to rebuild my phone.
ealterh
Turn off that live wallpaper! JK hopefully that isnt the case...
Each Android iteration on the GN has gotten smoother for me. 4.2 is pretty amazing out of the box, much like 4.1 was when compared to 4.0.3/.4. The GN is definitely not lacking when it comes to having what it takes for 4.2.
4.2 is really, really fast. When they fix camera rotation and recent apps, it will be perfect. It killed my urge for N4. Now I can easily wait for one more year... Good job Google.

How to fix lag in 4.2.2 system wide.

I have stock gnex on takju, since 4.2.2 I have suffered from lag all over the place, the lag could be fixed by restarting the phone but it would eventually come back.
I have only 300MB of data plan and I noticed that Facebook and facebook messenger where using about 50MB a month on the background without any user interaction and just a couple of days ago I started seeing Facebook app as the second most battery using app just behind screen on, this made me uninstall Facebook and and I instantly saw performance go up all over the place, it was night and day comparison, my phone feels like new and the buttery effect is back.
Now I installed Facebook back just to test and it indeed is the reason for my lag but this time I used greenifyed it and it fixed the lag too.
So there you go, hope this helps

Does matter. I disabled background data (as opposed to removing the app entirely) on Facebook and have noticed substantial speed improvement instantly. The only place you can do it, that I'm aware of, is from the mobile data screen when checking the apps usage.

There are two places to disable notification from Facebook on mobile.
The first would be to go into the settings by clicking on the 3 point button just right of the multitasking navigation key, then disabling notifications.
Second, by clicking on the top left corner button inside the Facebook app, then clicking on privacy settings --> notifications---> mobile push--> uncheck all
Sometimes I think Facebook deliberately tries to complicate the notification settings so as to keep pushing themselves on our faces!

Thanks for the tip, this actually helped a bit.
I've had luck with disabling auto-rotation for some reason. Caused SystemUI to lag after time. Hopefully it'll be patched in 4.3.
