Apple iPhone screen problem So I’ve noticed when my hand or anything gets close to the little dot on the screen above the speaker my iPhone screen turns off. It’s not the camera on the back or the front. It’s the little dot above the speaker on the screen.

Is there anyway I can stop that from happening?
It sounds like you are referring to the proximity sensor, which is meant to turn the screen off when you are on a call (so that your face doesn't press any buttons). However it shouldn't do it if you're not on a call. Can you clarify when it is doing it?
