Now there are official opengapps for android 10!)
I tried too. One problem was, the camera took off, remaining worked. I found not all settings. And icons in 4 rows widely I think. Icons quite children's but amusing)
Many thanks YumeMichi to you for your great operation !
By the way is there any way to disable hardware nav buttons in aosp?
I'm on 2nd September build.
Go to /vendor/usr/keylayout with root text editor and open file "synaptics-rmi.kl" and disable three buttons with "#" at the beginning of a line.
Screenshots of Dolby Atmos plz.
