Cyanogenmod 10.1.2-yuga randomly reboots - Xperia Z Q&A, Help & Troubleshooting

There seems to be no consistent pattern. The screen goes black and then the phone reboots. It happens during apparently very random actions.
Has anyone experienced this?

Display getting lit up on my note

Hi guys,
Maybe some of you have experienced this before, when I put my note away the screen of it gets lit up as if there was an app keeping it from sleep mode. But this happens even right after I have terminated all apps and processes. So technically barely anything runs. I think it might be a software issue? Any ideas please?

Install "Betterbatterystats" and you can find out the app causing your not getting into sleep

Crashing Issues

Has anyone else experienced crashing lately on this phone? Im using the APEX launcher, but occasionally the screen will just drop to black (backlit) and not respond to any key presses, except vibrate on a key hold. 20 seconds later after all key presses screens back on responding to the key mashes.
Ive also seen a few restarts lately, usually using google maps. Next time it happens I might see if I can catch the logs.
(Wish I had cyanogen again)
nope, been flawless so far, not frozen or re-booted, had a couple of apps crash, bout it!
Never had a crash on this phone...
I had one reboot after few hours of maps+music

Probably some apps that look for your location, to share or for better service, like weather, google, etc...
Check the settings.
I have some crashes with some widgets. Clear your home screen from every non stock widget and make the test.
Still trying to figure out how to use any widget without entire phone crashes.

From both of your reason, i can see maybe its from the phone gets overheated...it is possible as same like my previous phone, while using maps, i already noticed the back case seems soo hot then it just restarted...as you already know O4X having the heat issue...
Also it can be from that your system is too overloaded and cant find anymore free room to free up the memory...and overheated at tje same time....
Its just my opinion

Black screen

Sometimes when I open an app or close it or do something similar my screen turns black. It has a backlight on but its a black screen. I can only solve this by locking the phone and then unlocking it again. Also sometimes when I try and install an app from the market, my screen goes black and it reboots from the Xperia logo.
Any ideas, btw my phone is rooted correctly so that is not causing the problems

Brightness changing on its own?

I just got my XZ1 Today and straight away upgraded to 4.3.
I am having problems with the brightness, I have turned the 'adapt to lighting' setting off, but each time i go to my home screen my screen brightness goes down, it also does the same when I go to the last page of the app draw. This also occurs when starting games, the brightness will go down in the loading screen and then go normal when the game starts.
Is this a bug/issue, or is this meant to happen? If its the former, is there a fix
Sorry if this sounds newbie
Thanks,
Alex

Try to get a logcat to see what may be causing the problem.
Try an AOSP-based ROM to see if the same thing happens.
