Hello people, I am new to a s20 ultra I bought this two days ago from a refurbished seller with good reviews, my phone cant see black, I have owned many samsungs before like Note 9, A20, S7 Edge, Note 10 +, Note 2 etc. I have never seen this before. Whenever I pull my screen to notification menu or when camera app is loading, even normal wallpaper set as default it comes up as this green black pixely color, with green and black in a pattern together, the refurbished phone has a '1 year guarantee '.

What should I do? Is there any way to fix this issue without replacing screen, I have experimented with 120 hz, Fhd+, WHQD, brightness etc.

Hey @AJ20Ultra.

Please attach a picture/screenshot of what the display looks like. Also, if the screen is damaged then you can experience such issues with the phone, so check for any noticeable damage.

The phone is in pristine condition, I can not find any scratches anywhere, on the back, front screen, sides etc. This is the only defect I found. Screen is fully functional, I have used *#0#* test menu screen test function and more apps. Every area is functional, I have attached a few images however it might be hard to see on camera.IMG-20240131-WA0014_1000000684_1706740749.jpgIMG-20240131-WA0015_1000000683_1706740747.jpgIMG-20240131-WA0016_1000000682_1706740744.jpgIMG-20240131-WA0017_1000000681_1706740742.jpg

It could be a simple settings or software crossover. One app blocking another, or more likely its been dammit or outdated software. I personally would of and did go S20+ as for some reason it has a way better chipset than the ultra. So left me plenty of scope to play. Fantastic. Hope that helps a little. Just start from software. Then components. Water damage does that to a screen...
