Freezing/SOD Issues on 4.4 KK Roms [Serious Discussions] topic




Hello everyone,

This Thread is not supposed to be some offtopic discussion or flaming etc.

I'm creating this thread because alot of people have to those issues, which results in spam in every dev-thread.
So why not create a seperate thread for exactly this issue? It might even help the developers find the cause.
If you don't have this issue, DON'T POST. SAYING "I DON'T HAVE ANY ISSUES, EVERYTHING IS FINE" DOES NOT HELP ANY ONE.


Anyway, let's begin :

If you've been using 4.4 on your G2, then you're probably familiar with the screen of death bug.

What exactly is this?
Well, since the first CM11 nightly there has been the following issue : When doing random things on your phone (let's say write a message), the phone would start to "slow down", "lag", " get sluggish". Whatever you want to call it. When you scroll up and down, it feels like using a single core device from 2010 with 800 mhz. Switching between apps causes the animation to stutter and be choppy (looks like 15-20 FPS?). Now, if you turn the display off and on again, everything's fine again. If you don't switch the display off, you'll get the screen of death (complete freeze of the phone, sometimes sound keeps playing and vibration works). If you now try to switch off the display, it will eventually unfreeze. I couldn't figure out the exactly how long it takes to freeze, but it seems like a 10 seconds.

Now why is this such a big problem ?
As you can imagine, there are situations where such a freeze is the last thing you want to happen (I understand that 4.4 is not completely ready, but some roms are being considered totally stable...which is clearly not the case). I have a lot of respect for every dev working on this device and i don't want to tell anyone what to do BUT i feel like this issue has not been getting the attention it should.
Because it happens on every KK Roms (PA, CM, Mahdi, Vanir etc.) it's even worse. Some people advice to disable TB, SuperSU Notifications, undervolt etc. but that doesn't help.

So what can we do about it?

Probably nothing. But we can post our setups. When and how it happens. Which Roms is being used. What Kernel and so on to give the devs atleast a bit of insight.
So please use this form :

How often does it freeze :
When does it freeze (apps that are being used at the time of freeze) :
Logs (if you can provide them) :

How often does it freeze : 3-4 times a day (i can prevent some by turning the screen off)
When does it freeze (apps that are being used at the time of freeze) : During random tasks such as chrome, youtube, reddit sync etc.
Logs (if you can provide them) : Will post some later and edit. Don't have access to my phone right now.
Comments : Stock Voltages (raising does not help), Ondemand/Interactive GOV, ROW, Stock clocks.



Once again, please don't clutter this thread with unneeded discussions. If it helps to solve the problems it's totally fine.
