Got a used S21 Ultra from Amazon a couple of months ago. Overall condition was brand new except for the fact that the Bluetooth was way worse than my S9+ and the bottom of the screen flickers randomly, usually have to turn off the screen and back on for it to stop.

Also got a weird message in the update software section that my version isn't even supported. I kept the phone because I've tried two other sellers and the phones were worse than the one I kept.

Your current software version isn't supported. Visit a service center.

Hi everyone, what is everyone playing this weekend ? I've been playing Ghost of Tsushima for the past couple of weeks, really refreshing for somebody who is a huge Assassins Creed fan.

Quick question though, after I turn on my Portal from completely off, it sometimes only has the option to connect to a ps5 instead of the usual options to toggle to Streaming. It comes back to normal after a quick turn off and turning it back on. Is anybody else experiencing this ? Just wanna know if its my hardware problem or a software issue
