I replaced the screen on my iphone 4 because it was broken but now the proximity sensor doesnt work. Anyone deal with this before? Latest software.

    Who replaced the screen? Was it an authorized Apple repair service? If so, return the phone and have it checked. If not, you're out of luck warranty-wise.

    When you say "you" replaced your screen, what do you mean? Who actually replaced your screen? Apple typically does not replace screens. Instead, they offer an out of warranty replacement for $199 in the US.

    I replaced it myself. Will they know the screen has been replaced?
  • rbrylawski Level 6 Level 6
    Yes they will, and for that reason, you have completely voided your warranty. The reason people should not replace their screens themselves is there are electronics built into the screen and interface of the phone. This is why your proximity sensor no longer works. You are completely out of luck......

    Maybe, to at least avoid losing use of his phone, he could use Call Guard. Of course, there is always the speakerphone or blue tooth, but those aren't always appropriate.

    How will they know?
  • rbrylawski Level 6 Level 6
    Really, you're asking how Apple would know that you replaced your screen? When you took apart your phone, they'll be able to tell and it's really unlikely the screen you put on your phone was an Apple screen. And you likely didn't connect the electronics correctly anyway.

    You messed up. This is why Apple doesn't replace front screens instore in the first place. When someone brings in a phone with a broken screen, they charge an out of warranty replacement of $199 and that's all you would have had to worry about.

    Since you chose to void your warranty, you're out of luck.......

    I usually never write in posts but you my friend, rbrylawski really made me want to say something.

    first of the guy did not ask you what you thought about him replacing the screen. second Apple does charge 199 dollars to fix a broken screen which is absurd.


    ive replaced a couple hundred iphone screens in the last few years and I beleive it is a better alternative than paying apple for thier outrages support prices. second the iphone 4 screens that are sold on ebay are the same exact ones in iphone 4's. straight from fox conn in china.  and apple doesn't even check to see if you replaced something. they simply swap it out.


    so kudos to lcukyduck to replacing his screen and goodluck with finding a solution, maybe you left a piece of plastic cover on inside. also most ppl forget to replace the little plastic piece that goes in the inside right by the proximity for the flash.


    you aren't out of luck.

    rbrylawski - get out of apples *** its just a cell phone and we can do whatever the heck we want with it.

    Good on you, I am having the same problem after replacing my screen (purchased from China for $39.80) I was an electronics tech by training so was no big deal. I did have a little strip of plastic leftover from around the camera, are you saying this could be the cause?

    Cheers, and well said

    Did you find the problem?

  • xTylerB08 Level 1 Level 1

    i just made this tutorial on how i fix this problem. So far its worked like a charm.

  • Jefurlan Level 1 Level 1

    My 2 cents here: I have replaced the sensor/ microphone/ lock switch array and found that there is a small lens on the original proximity sensor (a smal color changing tinted plastic). If that little piece got stuck to the original screen with the small foam piece holding the sensor, the replacement won't work at all. Once I replaced the lens on the new assembly it works perfectly. Hope this is useful to any one.

    I shattered my Iphone 4 screen. However; my screen still worked just fine. It was only the glass that was broken.

    I ordered a replacement screen and after disassembling the entire phone, and at the beginning of reasssembly, I found the the prongs or connectors whichever you call them did not match up. When comparing the two screens, I noticed that my Verizon Iphone had the prongs in the corner of my phone and the replacement screen had them a little lower down on the screen. Just a slight difference. So, I could not use the screen new screen as it would not line. I then chose to reassemble my phone with the broken screen. After assembly was complete, I powered up my phone to find that only the bottom  half of my touch screen worked. Why is it doing this? And how many versions of the screens are there? I am thinking mine must have been the AT&T version which is constructed a little different than the Version Iphone4. Any thoughts on this would be very much appreciated.

    try going to settings,genral settings,reset all settings if that doesnt work use electrical tape over the proximity sensors because usually replacement glass lets too much light in to the sensors.
