My NOTE 20 went in for repair because of a sim reader problem it's come back and I've just noticed on darker/black screens it shows marks. Is this something to worry about?
it wasn't reading sims,I've barely used it got it in September from EE and and 2 weeks later it stopped reading sims,sent it in for repair 5 times they couldn't figure it out until the last time where they finally repaired it,warranty covered it but it's still not good enough and now I've noticed this 😤
