Smear on right side of screen - just below on/off button

[Caulkhead]

I seem to have a permenant smear on my screen just below switch. No matter how often I clean it is still there. Had same problem with my S19.

Anyone else have this issue?

Yes with my 1st Moto G in 2013 (very early gorilla glass had that issue where I used my left thumb to scroll the screen) but not since. Have you tried buffing it with a barely damp microfibre cloth?

Hi. Yes, I have. Wondered if the battery was in that area?

Not sure about your S20, in the old Moto G the battery was nowhere near the smudge. I know what you are thinking though about heat baking the skin oil into the screen glass

S19?!

If it has a pre applied screen protector, then it's just the adhesive. Unfortunately you'll need to replace it if that is the case.

S10! 😁

@Caulkhead: Bit of a long shot, but can you try heading to Settings > Display > Edge Panels > Handle, and use the up/down arrow to readjust the position, just to ensure that this isn't the source of the issue. If this isn't applicable, please dial *#0*# into your telephone keypad and select Red, Green and Blue from the series of grey tiles. Does the issue show up in any of these tests?

Hi AndrewL. Tried both, to no avail. 😢
