I've also got the Onyx Neo's, and I can stand on the other side of the flat without any quality loss or cutting out
Seems to be related to your specific unit/batch of units
If they still have 20.1.21v1, they can use that too, it's as stable as 20.1.16 imho
Or they can wait a bit for the rerelease, I would except 1-2 days, however nothing official has been yet said
Did you flash the later release? That has working rotation/ light sensor, no TWRP that encrypts s**t and no camera crashing
My battery lasts the same as on EEA official, so I have no complaint in that regard
I haven't tried GPS, so I cannot confirm
