AndyRM , via OnePlus 8 Pro , Sep 13, 2020 : Been using the 11 open beta for a week or so. The problem with the phone switching to silent or vibrate at random (with the switch remaining in the rings position) continues. Android auto on my Skoda (VW in effect) mainly works after a delay of 1-2 minutes after starting. - sometimes it does not and I sometimes get a screen like a tv screen when the Ariel is not connected and other times it still managed to lock the screen. (I have both the Google smart lock set to unlock when in car and the don't lock screen when charging set on). AA is something a lot off people rely on for their every day living. I don't know if the fault lies with oxygen or Android but it would be nice if the oneplus team could communicate on this matter and if there are any work arounds that would be nice to know too.
