Hi I recently replaced my lighting port and f cable but now I’ve noticed that the front facing camera and ear speaker are not working which suggests maybe cable damage but what I don’t understand is that I never moved anything in the screen half of the phone as the parts I replaced are contained in the case half? Any ideas?
it could be that the ribbon for the camera and speaker got damaged, i would suggest replacing it to see if it eliminates the problem. just follow the steps in this guide. iPhone 6 Front-Facing Camera and Sensor Cable Replacement
