@mankokoma Thanks for the summary! I noticed as with one of the previous versions to get it back to being quick and fluid takes some time on a charger with full battery and a restart or two maybe.
My observations for Redmi Note 8 (ginkgo):
The update installs and runs well after a dirty flash with the TWRP from
@geoanto555 and
@gkalen
Widevine is L3 as to be expected with A11 update.
There is a message about Xiaomi SIM activation service that pops up frequently if you are in Settings
I had my static wallpaper disappear a few times for no reason.
Google Assistant corner gesture seems to not work, just shows the animation and nothing, I will look into fixing that if it is not a ROM bug later, I have disabled it for now.
Left the phone alone on the charger for the night to finish the update and now the RAM usage is the same as with A10.
The kernel is changed from .177 to .190
There is Sound Assistant now which I think was missing before.
It is A11 (obviously).
Let me and everyone know if you find something else out.
