The iPhone 4 proximity sensor is suppose to detect when your face is against the glass and turn off the screen, so that you don’t inadvertently press buttons or accidentally mute your caller. Problem is sometimes the screen still lets in some light confusing the sensor into thinking it’s not being covered. What we’ve noticed is this problem is inconsistent. Some sensors seem to be more sensitive than others. Here’s a pretty simple fix we’ve been using with high success to alleviate the problem.

  1. Yeah it worked for me as well!!! So F*CKNG amazing to be able to make a phone call without muting/loudpseaker etc… wierd soloution but it sure worked out! Many thanks!!

  2. worked for me, you can test if the uv light is working by making a call and looking at the sensor area with a digital camera (another mobile will do) at least this will tell you if its plugged in and working.

  3. Yes, you have to take the iPhone screen off to access the area in which to perform this fix.

  4. This worked an absolute treat. I was concerned that I may have had to stop repairing IPhones as I kept receiving numerous complaints about this problem.
    Thank you so very much
