There is a few problems that I am facing with my s20 relating to the YouTube app, I pay for YouTube premium which enables background play, when I lock my screen about a minute into what ever song/video I'm playing it always randomly stops until I wake the screen (still locked) this is really annoying.
Second problem, when I open up the YouTube app it always crashes straight away, freezes and then starts playing after 1 minute, then pops up with the error message to "send report to Google" which I do everytime btw.
What I have done to try and fix - updated the app, cleared the cache, and factory reset the phone, this is really annoying and not what I expect from a phone that is considered a flagship from 2020, I've had the phone for 9 months and it's in near perfect condition.
