Thread: IPhone Call Lock Screen Problem

  1. #1
    Default IPhone Call Lock Screen Problem
    Ok here's my problem.
    In the past the iPhone had to be replaced by an LCD and I got that fixed.
    However, when it makes calls it doesn't lock the screen so I accidentally press buttons. I'm thinking it might be the digitizer. Also anyone know the price of a legit apple 3Gs LCD because I notice it, it's faintly yellowish. Please help. Thanks before hand MMI community

    that sounds like the proximity sensor not the digitizer. whomever replaced the lcd might have damaged the sensor. as for a legit apple lcd i'm not sure, i have bought approximately 20 from ebay for repairing others phones and have never had a problem with any of them, just make sure you buy from a power seller with very good feedback and you shouldn't have a problem

    Where is the proximity sensor? and yea I bought one for 17 but it's kindof yellow..

    Proximity sensor is Flex Cable #3 of iPhone 3g/gs. Location is under that irregular metal cover plate on the back top of screen mid board assembly.
    Hopefully the logic board connector #3 was not damaged.

    Good luck,

    The port is alittle damaged in the middle of the part. How do I fix?

    If flex cable #3 is damaged you need to get a new cable. If the metal plate cover over the flex cable #3 is bent, you can carefully just bend it back to the correct shape. This metal cover has a very complex shape to begin with, so make sure you know what a good one looks like before you mess with it.

    Good luck,
