iPhone 4 proximity fix after screen replacement
Heres a small tutorial i'm writing becuase i found alot of people having this same issue. Without any answer, i found this fix for the proximity sensor after doing color swaps or screen replacement on the iphone 4.
This is how i fixed it.
What you will need:
-electrical tape
-scissors
You have to be comfortable with dissasembling your iphone 4 all the way to taking the front LCD+digitizer off.
If you do not know how, search it on youtube there are plenty of tutorials.
Once you have the front screen off you should see the front of the housing:
Once you are here, you can see the 2 tiny squares on the top above the phone (ear) speaker.
These are the proximity sensors that you will need to construct a "mask"with small openings to only let a minimal amount of light into the sensors.
I took a small piece of electrical tape and cut it into 5 small strips.
2 slightly longer than the other 3:
Then you take the 2 longer pieces and place them parellel to eachother:
Then you add the 3 shorter pieces across the 2 parellel strips like so:
By doing this you are creating a mask with 2 pin sized holes to put over the sensors.
You then apply this mask lining the holes up over the sensors like so:
That is it. Reassemble the phone and make a call and the proximity sensor should work. Ive dont this little tweak on a few color swapped iphone 4's and it's worked perfectly everytime. If it doesnt work the first time adjust the holes over the sensors again.
I know it looks sketchy but for someone that wants a color swapped phone and wants the proximity sensor to work this is a great fix.
