Approximity Sensor not working after reassembly
i changed ths LCD Panel on my iPhone 4 using the guide of ifixit. Everything went great and my Phone is working great again. The only thing thats not working is the approximity sensor. Making a phonecall is nearly impossible ... because you always turn on the speaker or you cancel the call.
Does anyone have a clue why the sensor is probably not working anymore?
The screen filter over the Light and Proximity Sensors is either blocking or allowing too much light through. Some fixes include transfering the old blue filter to the new screen, using sharpie pen on the screen on the area, or even using tape with small holes over the sensors. Hopefully someone will reply with the best fix for you.
