Permanent dirt/stain spots on screen — nothing is working
I’ve tried glasses cleaner, a little water, even a dab of toothpaste rubbed in and cleaned off with a microfibre. I’m starting to think these spots are permanent, but I have no idea what caused them. I was eating a bowl of ramen next to my phone when I noticed them, maybe it splashed on the screen but I can’t imagine that leaving permanent marks. Any ideas?
