I had to share this great discovery. Every OLED panel has a layer of Oleophobic coating that works like Teflon. It mostly prevents fingerprints, smudges and other surface blemishes. When your screen starts to collect fingerprint smudges, then it has been eroded. A quick way to erode is using rubbing alcohol, which was my problem. Since COVID-19 I have been using rubbing alcohol and hand sanitizer. I doubted that you could restore it without being forced to get a new front panel.
I did research and found this and it's in sale on Amazon for $20
I usually get a tempered glass screen protector that is either matte or I use a microfiber cleaning cloth my screen still has that layer on it because the moment I get the phone I put a screen protector on it I don't allow my phones to not have a screen protector I always have one and back up
