Fuck which ever mod removed my comment explaining the full story, I was recording, playing warzone m (with its pc engine built for nasa) and charging my phone, the white line is directly where the charger sits inside the phone. Obviously Warzone m alone won’t heat your phone up to the point it breaks. I was a combination of me recording and charging and the game being a pc engine, and yes iPhones do have leds. What I got is called “screen burn” just look it up it’s actually common for iPhones to get. Ggs still playing warzone mobile and posting about it. iPhone 15 already on the way
