iPhone 5c Proximity Sensor Not Working After Screen Replacement

iPhone 5c Proximity Sensor Not Working After Screen Replacement

After changing the screen on an iPhone 5c the proximity sensor does not work. After noticing it did not work I took the phone back apart and repositioned the front camera and proximity sensor. After a hard reset it still does not work. The front camera flex cable has no tears so I assume the problem lies on either the screen not allowing enough light or ... That's why I post this question on this forum. Is there any simple troubleshoot like before on the iPhone 4/4s? Is there anything I'm missing that is simply over looked? I examined the original apple screen around the proximity sensor and it matched my replacement screen. I am simply asking for any tricks or tips from others who have encountered this problem..

I don't know if this would work, but is probably worth the try. I know on the 4/4S you could use a sharpie to black out the proximity sensor to get it to work in most cases.

"hi,

I have had the same problem in the iPhone 5s , when i replaced the screen, I didn't pass these two little parts shown here onto the new display assembly , and the proximity sensor didn't work afterward. One of these little plastic parts is the front camera lens, the other is a little bracket meant to hold the proximity sensor in place. You may need a heat gun to heat the glue to get these little parts of your old assembly.

Never had this problem with 5c why don't you try the camera flex cable in the old display if you can and check if it works with the original glass. If it doesn't you no that it's gotten damaged somehow

"I have noticed the same thing. It can be one of several things, but I have not been able to pinpoint which one.

1. I know that the (I think) ambient light sensor is ripping off of the cable when I am removing it from the old phone. This could be causing a short.

2. The other thing that could be causing this (more likely) is a little white rectangular piece of paper/plastic (?) that needs to be transferred from the old front to the new one. I think this does something like filter the light through the right way. I have noticed it makes a difference, but doesn't always fully fix it.

3. Finally, sometimes scratching off the paint on the pinhole of the screen allows more light to come through, but this is also hit or miss.

Sometimes putting the phone back together with a shattered front on it allows it to work again. This leads me to believe that the fronts are defective. I'm interested in hearing more from other techs working on these as well... really weird issues. Proximity has always been a problem on the GSM 4, (sometimes CDMA, very rarely 4S). I saw it pop up again on the 5/5s/5c fairly often..."

"Out of all the iPhone 5 and 5c I have never had 1 issue with the proximity. Now some phones I have replaced screens in had screen replacements before by another repair guys and left out the little filters for the 5c and brackets even still the proximity has always worked even without..

It might be the glass that's the problem from your supplier"
