S21 ultra u3 demo remove?

Hi welcome to AC!
This a demo phone ?
Where did you get it?

Welcome to Android Central! It's hard to see the details of that image -- can you try attaching the image rather than embedding it?

If the actual Firmware Version mentions that it's a Demo version, then it's most likely a demo firmware for a floor model. Considering how new the S21, it's highly unlikely that any legitimate store would be selling their floor models yet, so I'd be concerned about where you got that phone.

I would guess that the only way you could get rid of that would be to root the phone and flash the appropriate stock ROM.
