I'm currently on AICP LP stock kernel and stock kernel settings, but this happens in other CM-based ROMs as well as stock 4.4 ROM.
First it was rebooting during call, then I flashed different ROMs, to no avail.
Then I realized that it doesn't reboot when charging. So I suspected the battery, replaced it yesterday, no use.
This morning I found out that it doesn't reboot when calling with the screen on, and therefore I suspected it was some power saving settings that activate only when on battery and screen off, that causes the reboots during call.
I found the battery setting was in balanced mode, and changed it to performance mode. So far I made more than 30 test calls, no reboots.
So in short, reboots only occur during call while on battery with the screen off and not in performance mode, and in this situation they occur fairly often, like once every few minutes of calling.
Although it seems to be working now I'm still curious about what the problem really is. Since it reboots in a clean stock 4.4 KDZ install, I suspect there is a hardware problem (I haven't tried the stock ROM on the new battery though). What do you think the problem may be? What's the difference between performance and balanced modes that could have caused it? What further diagnostics can I do to find the real problem?
Thanks in advance!
