    1. DO NOT Report bugs if you're running a custom kernel or you installed Xposed
    2. 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.)
    3. If it is a random reboot, grab dmesg . (Do not bother getting a logcat unless you can get it just before the reboot. A logcat after a reboot is useless)
    4. If the problem disappears after running "setenforce 0" from a root shell, grab /data/misc/audit/audit.log
    5. 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.
