The definitive unresponsive touchscreen topic [Black screen of death] - Samsung Galaxy Nexus

As apparently many of you have witnessed before, there are situations where the Galaxy Nexus becomes unresponsive to touch input.
For me, this most of the time is noticeable when trying to unlock the phone. The phone just doesn't respond to me trying to unlock the Screen Lock (Setting: Slide).
The only way to get out of the situation is pulling the battery and reboot. One thing I notice after this routine, is that the phone has lost a lot of battery juice.
I've read a lot about this problem on multiple forums (XDA of course, but also Google support etc) and none of them have been able to pinpoint the exact cause.
There are, however, a couple of applications and settings that are more likely to cause the problem, but feel free to mention your own "suspicious" apps.
* [App] Light Flow
* [App] PGM Nexus
* [Setting] Auto Brightness
Please let me know if you've ever encountered above problem, on what version of Android you are, and if you're using on or more of the above apps/settings.

Had it on CM10 stable, disabling pgm did the trick. (I use auto-brightness but no lightflow)

I had this on rascarlo 4.2.1 /w Trinity & Franco kernels.
All I had from your list was;
* [Setting] Auto Brightness
I was also reading the developer options animation set to below .5x could increase the SOD.

So .5x is still okay?
Furthermore, could you tell me where you read this?

I'm unable to test out the animation theory as I'm back on 4.1.2 for now.

[Q] Display brightness problem Rhod100 on android

Hi all.
I have problem in android with display brightness.
When i boot from winmob to android brightness on maximum like in windows mobile. But when he sleep first time or i press power button and then wake him up by pressing power button brightness become lower. In settings brightness on maximum. I try move from max to min and move back to maximum but brightness don't become to normal maximum like in first after booting.
I tried different kernels but it don't solve my problem.
Any body have same problem?

First, wrong section. This should go in the Android section, preferrably in the build thread for whichever build you're using.
Second, if you had tried that little search button you would've found that yes, this is a bug. I believe it's even on the tracker... Again, if you had searched you also would've found some workarounds. Good luck.
Thank you for reply.
In android section i don't have rights to create thread.
This bug in every cwm builds which i used with any kernel. Exclude last kernels from october. I used search before but don't find workarounds with touch pro 2 brightness bug. If you found something can you give me link.
Thanks.

Thanks for reply, arrrghhh.
I install XDAndroid FRX07.1 not CWM.
And is not solve problem. On Rhod100 brightness after first display shut off lower around on 25%. Autobrightness also after first display off not working.
If any body have same bug can you give link where this problem solving?
Thread moved.
At least try to search, OP... FFS.
Search FRX07.1 thread for "brightness".
Amazing.

Touch sensivity working really slow

My GNex touch screen is working really slow. Is this due to the new AOKP ROM that I installed? This started happening only after I installed this new ROM. Please help
It's a software issue all around. I have it too on CM10 and had it on stock.
Sent from my Galaxy Nexus using xda app-developers app
But it only started happening recently, how can it be a software issue? Will it get fixed if I flash to stock or the previous ROM I was using?
It's apparently a widespread issue, maybe you didn't realize it until recently? I didn't either until a few days ago when I read the thread about it.
I think it is an overexaggerated issue..
Mine is no worse than any of my other android phones were, I have no problems with it whatsoever
Get the Franco Kernel app and adjust the input boost in the governor control.

to u maybe, to the people facing it it's annoying.
This help a little, not sure if it is a placebo or not. In the developer options set the following to "animation off", window animation scale, animator duration scale and transition animation scale. This turns off some of the fancy menu/window open and closing effects that make the cpu work a little less.

[Q] Screen going black?

Rooted VZW Galaxy Nexus (toro) ..
Since (what seems like 4.2.1) (liquid smooth, euroskank, cm10.1..) using three different kernels.. (air kernel, tiny kernel, zenx..) I get the screen to go black at random times.
Volume indicates it is alive, battery pull brings it back..
I'm not UnderVolting, or Over Clocking.. happens more often with Waze (GPS Navigation app)..
I'm in the car using the sock vzw (MiniUSB Dual Vehicle Power Charger w/USB Port) ; but I've had it happen while I was charging it via a wall charger as well..
[Q] How can I try and track this down?
[Q] Is this happening to anyone else?
Thanks in advance..
I'm not playing any games of any type..
I'm a network guy running around 12+ hours a day talking on the phone, sending/reading emails and texts.. and using FourSquare to checkin with other guys on the team. All of which are still running 4.1 of some flavor with other versions of the mentioned kernels/roms.. (I'm wanting to keep liquidsmooth b/c its super tiny..)
[Q] Is Linaro my problem?
Using 'Kernel Tuner', ZenX Gov, 218-1228Mhz, Row Scheduler, Fastcharge, and 8,16,32,64,96,128 for my oom..
No gpu OC/UV either..
## UPDATE ##
I just saw this in the Dev Thread..
http://forum.xda-developers.com/showthread.php?t=2080690
Replicating 4.2.X "sod" and what it means..
Looks totally like my issue.. and I didn't think it was a Sleep-Of-Death or Screen-Of-Death b/c the controls still worked..
which is what is said in the thread..
(sorry for duplication..)
see this issue and the workaround.

or my full post http://forum.xda-developers.com/showthread.php?p=37360907#post37360907
So, 'some animation' and auto brightness is "stable"?
Or 'some animation' (.5 or higher) and NEVER auto brightness?
I am not clear on that.. (thanks for this.. glad I'm not alone..)
You can keep auto brightness along with x.5 animations in all 3 options.
You only have to set animator duration to .5 or higher. You can turn off the other two animations with no sod

[Q] Lollipop, The Aggressive App Killer

Does this even need an explanation? Lollipop kills apps like it's his hobby.
Even with only a few light (on RAM) user apps running in the background you sometimes find yourself staring at your launcher home screen that, you could've sworn, was just showing a different app a second ago.
Or the times when, after multi-tasking a bit, your phone starts becoming painfully slow. Turns out that some apps are so stubborn that they go on strike (continuously restarting) when LP kills them.
I'm sure many have experienced this. And I have seen some devs address this issue here and there. I though it would be useful to gather the info into one thread, to ease our (or my?) frustration on this issue.
What I wanna know is, what causes it exactly (why didn't it happen on KK?), and is there a solution to this? Or at some way to calm LP down a bit with his killing of innocent apps.
Thanks.

Im running 1/8 FML with synapse injected R10 kernel on my toro and with ksm and laptop mode enabled in synapse, I haven't had a launcher redraw in days. I don't have anything whitelisted either. However, the trade-off I have at the moment is I cant seem to stream videos on my stock browser. Havent tried a different browser or anything. I just uncheck those two settings and reboot and all is well, but my phone certainly works much better now, and no redraws, with neph settings for LMK
Hope something helps someone!
Thanks

Perhaps you can noobify that a bit, lol. I had to google almost everything you mentioned. As I understand it, this Synapse allows you to tweak the kernel? And this KSM settings can improve this RAM issue? Care to elaborate? And what is laptop mode?
I've read about adjusting the LMK values to calm LP down a little. Any idea though why this was so necessary in LP, but not in KK? Is stock LP 'naturally' more RAM hungry than KK?

I can try to elaborate little bit, as Ive been flashing things and researching xda a lot, but I am still noob in how/why things are the way they are. From what I gather lollipop just handles memory differently then kk did. I think that is some of the reason as to why the "recent apps" persist through reboots now. Remember, our device was not really supposed to run kk and certainly not meant to run lollipop. The developers here are without a doubt amazing in what they know and what they do for us users. A new kernel and driver was necessary to run lollipop on the aging gnex. Now, some of the issues we are experiencing is a google issue and will only seem to get fixed when they get around to it. I know my nexus 7 (old) has some memory issues and lag and redraws from time to time....not as much as I noticed with my gnex before the changes were made I stated in the above post. I recently helped my friend root and upgrade his oneplus one to lollipop and he has the same issues we all have, maybe not as bad, but they are noticeable
A lot of the questions you have, have been discussed recently in bsmitty83 kernel thread, since I asked them. There are links there as to what KSM and laptop mode are and what they do. KSM-kernel same page merging helps with RAM and I believe laptop mode helps to conserve power. A lot of these things are geared at devices with low ram like the aging gnex, but the developers have done a great job at making lollipop a daily driver. Most users I think use trickstermod from playstore to tune kernel settings, and that is ok, however, you must purchase the paid version to tweak low memory settings, which I did. However, synapse, also found on playstore can also be used to tweak kernel settings, but the kernel has to contain UCI support for the synapse app to work. Synapse has more settings available to tweak than trickster does, like KSM and laptop mode, which have helped me very much. The only kernel I'm aware of that has UCI support for synapse is bsmitty83 Full_Auto R10, because osmosis made it work
Hopefully this was rather accurate and helpful and not convoluted! ha.....im sure some more knowledgeable people will come and correct anything I said that may be incorrect, but in the meantime, read through the R10 kernel thread and see what you come up with
What ROM and kernel are you currently using?
Thank you

I'm currently using AOSP rom (by freshgimmi) and the Full Auto R10 you mentioned. I'll try injecting the new ramdisk now and see how it goes.
I noticed this issue as well for the first several days . However once I installed the new bootanimation from arter97 the issue doesn't occur anymore. Not sure if it's related but all I did was mount /system as rw and copied into the new lollipop boot animation from here: http://forum.xda-developers.com/android/software/arm-arm64-android-5-0-lollipop-t3032247

I know about this issue. It is a memory leak during boot. It is a good catch, though all you're changing is the bootanimation.zip. AFAIK, it should not affect your system's performance after boot, once your phone is up and running. My issue is a different thing entirely. I never got bootloops (that is, when not messing around with xposed).
Okay, you're right. As a test last night I switched from FML 5.0.2 to LiquidSmooth's LP ROM and I'm not seeing any aggressive app kills in LiquidSmooth.

I have got synapse up and running. I AM wondering though, what LMK settings are you using? Cause the neph settings I know of tell me to set empty app to 370, but synapse only allows max 320... If you're following different settings, could you link the post for me?

Glad you got everything up and running.....Im using Neph's settings for LMK, and your correct the empty app only goes up to 320 in synapse. There was a post somewhere where Neph said he was still tweaking his LMK values and I believe he mentioned about lower empty app to 330 or something, so I just set it to 320 in synapse and call it a day

How To Guide How to get rid of scrolling stutters in customs ROM.

Hi , it is just little hint that allows you to get rid of this infamous scrolling issues that appears mostly in social apps like twitter or fb on all AOSP based ROMs.
As I observed it is enough to set some touchboost kernel parameters. Of course you have to be rooted to do that.
Below there is a sample configuration that I use (set in Franco kernel manager) and scrolling is buttery smooth and also I didn't notice inscreased battery drain since I use it (though it it must be higer) .
I suggest to spend sometime to change those value to find sweet spot that suits your needs
Don't ask me about scheduler priority , I don't know what that values means , just know that 1 is fine (maybe other is better ) .
I shared this solution on TG group and some guys confirmed that this trick works for them.
Don't hesitate to share you favorite config and have fun
This was actually one of my main reasons not to use a custom ROM, thanks, I will definitely try this out!
Thank you for sharing this!!
It took me a while to actually find these settings. For those that also can't find it:
Menu > "CPU and GPU" > scroll down to the "Miscellaneous" section > "CAF CPU boost"

The menu of which kernel management application?
Ok I see. Sorry.
Works perfect. Thank You.
However, when you look closely, sometimes I see a slight leap in the animation. Which parameter can be increased to completely remove stuttering scroll animations?
Ok I think I know.

Input boost to 1500 but app drawer from time to time still have some problems with smoothnes
Wow that's a massive difference. I'm using the FPS overlay thing (app not settings) and it actually waits before playing with the refresh rate. I'm on stock not a rom yet, but the little hang ups on what is the latest and fastest chip was annoying me to all hell. Thank you so much (and felek73 obviously)
First impressions: responsiveness if fantastic, but battery drain is way higher (I had just flashed blu sparks and only done a half day, so will see in time) but before it was noticeably better than stock and the remaining 40% has gone by considerably quicker
How to I reset the frequencies to stock? There isnt a "0" option in Franco kernel, despite being that way initially
