Earpiece does not work after screen replacement
After replacing the screen on my customers iPhone 7 plus everything appear to be working except form the earpiece (When making phone calls I can not hear anyone). I have checked the camera flex and it is in perfect condition with n o sign of damage.
I have reset the settings already. I am in the process of backing up and restoring the phone.
The customers is in urgent need on this phone so any help would be great :)
