GN Screen occasionally becomes less responsive

I have had a GSM Galaxy Nexus for quite a while. I've had Stock ICS on it, as well as many different non-stock ICS and JB ROMs running on it.
I've noticed that, from time to time, the screen will become considerably less responsive than it usually is. I usually notice when trying to swipe down the Notification Window. I will have to swipe several times to get it to actually work, when it usually works every time, easily. If I swipe slower and apply more pressure, it works. Also, typing on the on-screen keyboard when this issue is occurring is a disaster. The system misses about a third of my touches, and mistypes every word practically.
If I reboot or wait a while, it goes away. I've been trying to shut down various often-used apps while it's occuring to see if I can remedy the issue, but so far I haven't found an app that might be causing the problem.
Anyone else have this issue? It's so noticeable for me that I can try to do the usual motion I do to bring down the Notification Window over 10 times before it will actually respond.
It's either something basic with Android, or my hardware has a little bug. Not sure which.
I see a few posts on the forums of other phones about this, but not on here with the Galaxy Nexus.

I'm having the exact same issues. Its also very noticeable in the keyboard as well. Sometimes in the app drawer. Its extremely obnoxious and only seems to do it on jelly bean Roms... may I ask what kernel you're running? I'm on Franco 223 384mhz gpu

hey man, i've noticed this same thing on mine running Jb (joel's bamf jelly)...i notice it when typing, though. a lot of times i just completely MISS keystrokes, and my words come out all ****ed up. i honestly was starting to think i'm crazy, but i'm glad to see others with JB are having this issue! again, if i reboot as well, it goes away. wtf?
i'm running whatever kernel joel has stock in hsi rom, which i beleive is just the stock JB kernel.

Exactly same issue here, but simply turning screen off and back on solves it. No need to reboot.

Running one of the early loads of 4.1.1 that required you to load 4.1, then overlay 4.1.1 over it to get get camera working properly. But it's stock minus being rooted/busybox loaded on it. Running the stock kernel with the JB baseband that released, btw.
Before that I was running AOKP and CM9, both of which did the same thing to me - which is what made me think it was an app that was interfering, but I haven't been able to prove that.

Search my thread called touch sensitivity, I wrote all about this. Its an annoying bug that has no fix. Lock then unlock the screen resets it and makes it return to normal. But it eventually happens again.

I also had this issue, and as someone said earlier, just switching the screen off and then back on fixes it for a while. But I recently updated my baseband to XXLF1 (yes, I'm from Europe) and switched to AndroidME CM10 Rom and the issue is gone (had been using the one from team inferno before). Don't know if it was the Rom or the radio...

Since alot of users are saying it was non existent in 4.0.1 and 4.0.2 was wondering if someone could look into the touchscreen drivers?maybe there is a glitch.btw sometimes it would not appear for a day

Yes, that's a good point to start.

I originally thought this issue was due to a kernel malfunction, but looking at the replies here, apparently not. I don't remember it happening on ICS at all, but with jelly bean and project butter being so smooth and all, I have recently become much more attentive to the responsiveness of my screen so it's much more noticeable. I guess the best thing to do is try different Roms and see if the problem persists.

Well, as stated above, CM10 seems to eliminate this problem completely. I just flashed a CM10 ROM and man is there a difference. It is extremely smooth and battery life seems significantly better than others ROMs on jelly bean right now. I highly suggest giving it a go. I upgraded my cwm recovery to 6.0.Something too. Dunno if that's relevant, but just thought I'd say.

Are you using the euroskank one? If yes then thats what im using too and still have this problem tho not worse than others, my keyboard works properly.just that my scrolling and swiping tightens up a bit which forces you to swipe longer and more pressure than normal

Did you find anything fix the sensitivity issue? It's super annoying. Screen off and back on fixes it temporarily.

I had this issue on 4.0.4 with the Linaro franco kernel and am now having it with JB and the Linaro franco kernel. I too thought it was just maybe my imagination!

Kernel Question

Hello all,
I recently purchased an S3 and just trying to figure everything out for it (as I am coming from the nexus where everything is much simpler) The only real question I have for everyone is, What kernel is the best so far? Something that is optimized for battery life and speed.
If anyone is from the Nexus development you would know about Franco's kernel which has served me well for a long time, So what I'm looking for is something that is like the Franco Kernel, and has customization settings.
Any insight would be great
Cheers.

When running an AOSP JB ROM (like CM10 or AOKP), I'd suggest ktoonsez's KT747 kernel. It supports overclocking to 2.1 GHz, undervolting, comes with numerous tweakable governors and io schedulers, and it comes with its own adjustment app called KTweaker which is very handy. Just don't use SetCPU or Voltage Control or any other such app with that kernel as they could cause conflicts with KTweaker.
http://forum.xda-developers.com/showthread.php?t=1756776
The current KT747 for Sammy ROMS seems to be having issues with many phones though, so for Sammy ROMS I'd say your safest bet is faux123's kernel. http://forum.xda-developers.com/showthread.php?t=1785466

Much appreciated. I was seeing ktoonsez's KT747 kernel, and figured this was the "main" kernel for the s3 but I just had to know for sure. What you describe with it is exactly what I'm looking for in a kernel...full control of it. Thanks again

Also on KT747 ktoon created his on governor called ktoonservative. It's based off conservative but it's kicking some serious butt with my device :good:. I'm also severely under-volted but that shouldn't really change much as far as battery life.

I tried the kernel (both actually) and had no luck with either, one caused everything to fail ie: wifi, data, launcher, touch screen was unresponsive. And after flashing in the other one that says it is 100% stable on all devices, I was left with a phone that wouldnt turn on, and when it did start up, the screen was unresponsive. I tried clearing caches, fixing permissions, but nothing worked at all.
So I went back to stock kernel. Hopefully some of these issues can be resolved some day.

Are you sure you flashed the correct version? Both kernels come in ICS and JB flavors.
Also, I haven't seen anyone else with this issue so I'm not sure what happened.

CM10 M2 Lag after initial reboot, kernel issue?

Ok so to make a story short:
I installed CM10 M2 wednesday, everything went AWESOME. Smooth, responsive, fast! Pure JB awesomeness. Then, satuday i decided to flash Faux123 kernel to have additional governors and from that point, everything has been terrible. The phone has been extremely laggy, it randomly rebooted and sometimes when i turn off screen, it doesnt want to turn back on and i have to battery pull.
Since that, i have formated the phone at least 5 times, i tried just a factory reset, complete wipe through CWM, reflashing rom, but nothing worked. What really weirh though is when i reflash the rom, and reinstall all my apps and put everything back, until i reboot the phone once, the phone is smooth and stable. But as soon as i reboot the phone, i'm done. It becomes laggy again, reboots and has sleep of death.
I'm really perplex as to what can cause this. I honestly am just about to ODIN this phone back to stock and just wait for official JB...thats unless somebody here has a quickfix?
I'm assuming when we reflash rom it also reflashes kernel, maybe reflahing just the kernel will solve this? anybody got a link? or a kernel to suggest?
EDIT: Now i can reproduce the problem. Everytime i turn off screen and i turn it back on shortly after, it reboots

Try ktoonsez kernel. He seems to be putting more updates than faux. Faux hasn't updated since August and ktoonsez updated 5 days ago.

No he does update his kernels he just doesn't update them on original thread. My build version is Oct 13th. But ktoosez has cm10 kernels?

Ok, i've just installed Ktoonsez kernel. I have changed to different governeors and i've yet to have seen any lag. Thats a great sign. Juste one question though, what combo of governor + scheduler gives the best battery life?

I use ktoonservative and bfq, but there is no "best" What works best for someone else might not work well for you.
Testing is the only way to answer this for yourself.

[Q] Ridiclously slow!

Hi,
My GN was fine when I purchased it a month ago, brand new, but its so sluggish that its almost unusable. Phone dialer, Messaging and almost all apps load with a 3-5 second delay, even the keyboard opens after a few seconds.
I'm on stock 4.2.1 (deodexed) and even flashed fugumod kernel just today hoping it would fix things, I even factory reset it but no joy.
Could it be a hardware issue? is there any way I could run some quick tests to see whats wrong?

A similar thing happened to me when I decided to try a new kernel I've never used before, and it did not agree with my phone. Try a different kernel like lean kernel or Franco kernel and see if it still happens. If so, go back to stock.

I was on stock, then tried FuguMod, but it still lags, not as much as before but pretty slow.

Do you have lag spikes? Like many little freezes?

Just stock...should i change anything on the gov settings? Or the voltages? It seems that my device won't support some kernels. If you could tell me something to change for making it better,that would be great.

Have you used up almost of your memory in the sd card? I don't know if GN's are affected by eMMC bug brick. I've asked this before but they said GN is not affected. It has something to do with a bad chip.

4.2.2 The bad

Well all things were fine on 4.2.1 and then this update comes,
This is what i noticed so far,
1.Phone is EXTREMELY laggy when downloading from play store
2.Browser quick controls are bugged
3.Lots of launcher crashes
4.Alarm icon in the notification disappears while it's still active
5.Random lag spikes while navigating in de drawer or homescreen,
As far as i go, this is the laggiest jelly bean version, maybe google just got lazy, or they're working on another version of Android (fingers crossed)
EDIT: I'm not talking about custom roms and such, and i'm not willing to flash, i like stock

First:
Do a full wipe!
Flash STOCK ANDROID JB 4.2.2 (I mean stock, and not CWM flashable stock ROMs with root..)
Use stock Android launcher (Just stock, not modded or anything else)
And then Stop complaining!

I'm on cm10.1 4.2.2 and is probably the smoothest ROM I have ever been on.

1. Use a custom kernel and tweak the read ahead buffer size. With sio io scheduler and 256k buffer size i made the lag minimal for me.
3+5 : use nova launcher and it will be fine
4: it works fine here, make sure you do clean installs.
As a last advice I must say to flash the factory image via fastboot. It is absolutely fine with no issues. I installed it on 2 gnex' already and no problems with lag.

Stock android is far away from perfect now. JDQ39 is nowhere near rock stable JZO54K. My friend. Scrolling lag is not the matter of clean installation. I've tested five 4.2.2 based roms, including stock all of them lags as hell after a while - it can be one or two days or couple of hours. Actually it's been the most evident of stock and it concerns scrolling between homescreens, lockscreens, recents. A lot of people have experienced it and it's been already reported to google issue tracker. I've already tested stock, cm10.1 m2, PA 3.1 0309, XenonHD 6.0 - all of them lags after a while. At the moment I am testing Purity and I haven's seen lag for two days.
Te easiest way to reproduce the bug. Please do not reboot your devices, and do not change wallpapers for about two days.

Same here, on CM10.1 Play Store is now smooth but was bad on XenonHD.

Well I don't understand where do you see the lags. Because I don't have any lags on my nexus.
The speed also depends what kernel you are using and how much free Memory you have on your nexus..
I'm using my own ROM which is based of stock Android ROM and I have actually never experienced any lags.
Yesterday I got few apps after using apple's BT mouse and when I set up multi users.. But all the lags went away when I rebooted.

How do I do this?

Not sure if this has been discussed or not I searched and found many bugs but none that meet this specific issue.. I noticed that since I updated to the 4.2.2 leak on my Toro Nexus there have been a few issues:
Audio from the pogo pin dock stopped working.
Car mode goes off and on randomly as well as the charging bolt when the phone should be charging.
Phone goes into daydream mode even when not being charged..
Turning on bluetooth randomly reboots the phone on occasion and other random bugs.
I think I'm going to flash back to the previous OTA. I'm stock unlocked, unrooted, just the way I like my Nexus (for now). In no way is this a complaint, more my observations and a last shot in the dark to see if anyone has overcome these issues in the latest leaked "OTA."
On a side note, other than the dock and power issues, everything has been smooth. No lag etc...

Ok so I realize I don't know how to do this without resetting all data. From what I've read, the only way back includes wiping all data. Am I wrong? Is there a way for me to go back without wiping? I'm not super versed in all things Android but I think I recall flashing back to a previous OTA in the past to get another OTA to work without wiping. I can't find that thread anywhere so I'm probably mistaken. Any help?
Edit: I re-read http://forum.xda-developers.com/showthread.php?t=1626895 and determined that it can be done without wiping for folks that aren't noobs. I consider myself a noob at this point so I'm stuck with this 4.2.2 update until I find an easier way.

It's the same as flashing a rom! Use Titanium backup to backup the apps, and custom recovery to wipe data/factory reset, cache and dalvik cache. Format /system, /data, /cache , and downgrade with the toolkit w/o format when it ask. So for less than an hour you will downgrade, and keep music, videos and photos. So the only thing you lose is programs, but you can restore them whit titanium, and that is!

Lags what I am talking about is low fps scrolling that appears after some time of normal usage. I've never experienced it on 4.1.2 or 4.2.1. It has nothing to do with the kernel. (BTW aren't we talkin about the stock one?) Problem is still present on custom kernels and even OCed CPU. It looks rather like some sort of memory leak. Reboot or changing wallpaper is a workaround solution for this issue. So yeah if you reboot your device quite often you most probably won't see this bug.
If you want to read more about this issue visit this thread:
http://forum.xda-developers.com/showthread.php?t=2178962
Except this bug I really like the 4.2.2 rom, these new features. I consider it as an improvement from 4.2.1.

I agree, 4.1.2 was polished more. 4.2.2 is better then the initial 4.2 release, but still has a way to go. We'll see what IO brings soon.

Ok.. Hmmm.....
Are you using custom kernel?
And which apps are running in background? E.g. Currents, Google+. FB...
And if you use custom kernel then make sure you use CPU governor that doesn't make Android slower or laggier..
I have actually never had any lags on my Nexus, I use 100% stock kernel, sometimes CM's kernel. I have free memory 2,10 GB of 13 GB (16GB GNex)..
Also I recommend to use some cleaner apps to delete unnecessary files..
For cleaning a bit my Nexus I use "Mobile Care" on Windows it is "ASC"
Which deletes e.g. Cache and junk files..
