Proximity sensor not working after screen replacement
I had faced to this issue before.
In screen replacement , always I used front camera and sensors and home button from the old display.
Although everything work properly on old display, after replacement in most of the times proximity sensor is not working.
I'm experienced in iPhone repair,I put everything in right place and I try to don't touch FCAM and sensors as possible but this issue happen again.
I don't want to order full display replacement pre-assembled one.
Last night I faced to this problem again on repairing iPhone SE, (proximity sensor didn't work after screen replacement),I re-opened and re-assembled everything (FCAM-Ambient light sensor-proximity sensor-Receiver) but the problem has remained.
I also checked proximity sensor functionality with covering by finger while calling,It was not working anymore :(
Do you have any same experience or suggestion?
Is this a good question?
