I'm using this rom as a daily driver and as far as I'm aware, there are 2 minor issues with this rom:
Android Auto only works reliably when HW-Overlays are disabled in Developer Options (This is an issue that many, possibly even all AOSP-based roms share on modern devices:
https://forum.xda-developers.com/poco-f1/how-to/android-auto-issues-poco-f1-custom-roms-t3893305 ) It's annoying, because HW-Overlays get re-enabled on every reboot.
The device should support BDS, GALILEO and QZSS, but according to GPSTest only GPS and GLONASS Satellites are used for positioning.
Other than that, the rom is pretty stable.
