There's a white smudge on the inside of my iphone, what do I do?

Ok so I was watching a video and as soon as I exited out of the video I noticed that my entire phone had the same level of brightness, but there's this one smudge on the bottom left of the screen and I want to know what I need to do to get rid of it.

Could be just normal screen bleeding, look it up.

Just wipe out down with a damp rag, not too damp/ if you really want the get the smudge off without hurting the phone, buy a screen cleaner. It works nice. Are you sure its not just your screen a savor that has a sundge, not your screen, if you have a screen savor.

  • Tiny white light inside iPhone screen? I have an iPhone 4S and every time I open a page that's white a tiny bright light pops up at the top of my screen and I'm worried it may be damaged some how. My iPhone screen was recently replaced so maybe that has to do something with it. But I hope that someone has a solution to my problem.
