Samsung s21 ultra black circles on the screen

[UpgradeArtist60]

I have black circles on my screen tryed to get it repaired under warranty but been told that I damaged it. It started but the volume buttons first now 6 in the top left corner it start by a bright pixel the goes black then they expand how is it my fault when there is an issue with the screen itself I don't think I will be sticking with Samsung anymore.

Unfortunately as Samsung have found this as owner caused damage the 24 month manufacturers warranty wouldn't cover any repair work for free.

The Samsung Authorised Engineer normally provides a worksheet explaining their findings in most cases.

You could escalate this as a complaint ticket to see if they'll look at this again for you to provide a second opinion. 

Alternatively look at any relevant insurance which can range from mobile phone insurance,  home contents insurance or some bank accounts provide insurance as a perk of the account.

I wish all the best.

Check that your Developer Options ' Simulate Display With Cutout' is set to default, just to rule that out as the cause of this!?
