[Q] Troubleshoot shutdown on 4.3/4.4 based roms
My phone shuts down on 4.3 and 4.4 based roms.
It happens much less often on 4.2 and stock based roms.
It seems to happen when the screen is off. It doesn't shut down when I'm in the middle of doing something. I've seen that on other phones.
If the screen is off, but I'm listening to the music player or Pandora, it does not shut down.
It does not seem to be overheating.
I'm on my 3rd sim card in 2 months and my second class 4 SD card. I only bought a new one b/c used the one from my old phone and thought it was best to start fresh.
Currently I'm running the first CM11, but this has been happening on CM 10.2, AOKP, and a variety of other roms.
My recovery is TWRP 18.104.22.168
I use the regular GAPPS, not PaGAPPS and the appropriate GAPPS for the given AOSP base; 4.2/3/4
I flash SuperSu-v1.65 after a full wipe when installing new roms.
The current apps I have installed in addition to what comes with CM are:
Rom Toolbox Pro
UPM - Universal Password Manager
Xposed Installer - I don't have any modules installed at the moment and the last time today it shut down by itself was before I installed Xposed.
I know that logcats are good for tracking down errors for apps that FC, though I don't know yet how to read logs.
Is there an app I can use that can show me activity before the last shutdown?
How can I track down what's causing it?
