Things to do before reporting bugs:
1. Check if Magisk Modules are installed, if has, so uninstall.
2. Please send the log before reporting bugs, which will make it easier for maintainers to locate errors.
3. Don't report issue with third-party apps to the maintainer
4. Flash into third-party kernel, please restore to ROM built-in kernel and then give feedback.
5. No serious bugs don't PM maintainers (serious bugs: wifi, bluetooth, ril, kernel panic)
