Since I installed Quarx's CM11 06-09 or 06-10, don't really know, but my Defy Green have random reboot. I leave my phone in my pocket or on the desk, and when I have to use it, I see that it is on the PIN code screen. Sometimes, I just unlock the phone, and the reboot happens in front of my eyes. I have a catlog log file, maybe that can help finding out what can cause it. I'm new on this forum, and didn't know where to post it. Move it to the appropriate topic, if neccessary. Thanks a lot.
btw: Defy Green, Quarx's CM11 06-16, 1.2GHz @ 63Vsel
