There is a serious bug that need to be fixed. Whenever I enable Data Saver for Quick Settings, the system ui initially freezes occasionally for a few moments, then entire system ui( including the mouse cursor ) just freezes for about 10-15 seconds, after that a black screen appears with only mouse cursor functional. I have yo press Alt+F1, then type 'reboot' to force restart the system, and then the android gets stuck at boot logo. Had to reinstall to start all over again
Thank you
