Reporting Bugs

DO NOT Report bugs if you're running a custom kernel or you installed Xposed

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.)

Include your OOS base versions in reports. (Eg: 9.0.8, OB25, 9.0.7, etc.)

Mention any and all Magisk modules you might be using along with the Magisk version

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)

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.

Q: What OOS Base firmware do I use?

Q: I'm having high idle drain, please fix.

A: I'll need more data from you to figure it out, Install BetterBatteryStats and let me know about what it tells you after 3-4 charge cycles. Please do not report issues when having apps like Greenify, Naptime, Wakelock blocker etc.

Q: My phone is stuck on the "Bootloader is unlocked" warning page, why isn't my system booting?

A: Since there are a bunch of scripts being executed when the device is sent a power on signal, it might take some time to boot. Don't panic, your system will boot fine after some time. All builds are personally tested by me and a few testers.

Q: When I'm updating via OTA in the Updater, do I have to reflash GApps and Magisk? Will TWRP stay after I update?

A: When updating via OTA, GApps and Magisk will remain intact. Have a look in /system/addon.d/. Anything that is present inside that folder will stay after the update.

TWRP will not stay since A/B devices don't have a recovery partition for it to actually stay. You will be reverted to the stock recovery.
