What is this?

An AOSP based ROM, with gapps included and gesture support (pocket, hand wave, pickup).

Based on Android 10.0

Notes:

1. If you want to root then copy the stock boot from the latest stock rom into internal and use magisk to patch it, then flash the patched boot in bootloader (fastboot flash boot patched_boot.img)

2. I will try to provide monthly patch updates and fixes as needed, don't ask for ETAs... I usually aim for the 5th of each month or whenever Google releases their patches

Bugs:

* voLTE not enabled by default, you can try this app and see if it works. some users report network drops or sms causing crashes.

You tell me? I worked hard to get everything working, I don't see any other issues, please report real issues, not feature requests from MIUI or other roms.
