I have no problem during calls and when recording with back camera butto when i make video with fronte facing camera and use FaceTime people dont listen me and i cannot record any audio. what’s the problem? I can repair It? If i buy a LCD screen replacement with all components?
It’s probably just a faulty front camera assembly cable, a very inexpensive part you may replace yourself if you’re careful enough and have basic tools for opening up an iPhone 6. Here’s the guide with the howto..if you want to purchase the part from iFixit you’ll find the link to the replacement in there too: iPhone 6 Front-Facing Camera and Sensor Cable Replacement
