DO NOT report bugs if you've installed xposed and/or other mods

Grab a logcat right after the problem has occurred. (Please include at least a few pages of the log, not just the last few lines, unless you know what you're doing.)

If it is a random reboot, grab /proc/last_kmsg. (Do not bother getting a logcat unless you can get it just before the reboot. A logcat after a reboot is useless)
