Solved Earpiece Not Working But In Different Phone Is Working Iphone 5C

Chosen Solution

Hi everyone I have problem with one iPhone 5C, the earpiece won’t work but if you press on it works. I replace the screen with new earpiece and new proximity flex that are working in different device and still it doesn’t work when I place back in the phone. Anyone had this issue before? Thank you for your help

Could it be the screen frame? I’ve seen screen frames where they have caused horrible installation of the metal plate and two screws for the earpiece / front camera assembly.

Probably you have damaged the J1 connector or a part near this connector. See the schematic, check pins 24,26,28 and parts that connect to this pins.
