F1593622792211 , via OnePlus 8 , Oct 27, 2020 : Since I updated my new 4 months old OnePlus 8 to the latest update (Android 11), the screen suddenly does not turn on and goes black. I hear notifications in the background and I can change volume with the side button however I can't see nothing. It's full black screen. This has happened three times in a week. I had to hold down the power button and lowering volume button to restart phone and everything was back to normal. Is anyone else experiencing this issue? This is not acceptable for a new 1000$ phone.
