Reporting bugs

You are allowed to report bugs only in this thread.

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)

If the problem disappears after running "setenforce 0" from a root shell, grab /data/misc/audit/audit.log

Remember to provide as much info as possible. The more info you provide, the more likely that the bug will be solved. Please also do not report known issues. The following is a useful format to follow.

What is your:
- Phone model (I9105 or I9105P):
- Radio (baseband):
- CM version:
- CM Download URL:
- GApps version:

Did you:
- Wipe:
