Chosen Solution
I replaced my battery on my I phone 6. I struggled getting the adhesive off and noticed a split in a cable where the phone pieces together. I’m trying to figure out what part I need to replace what I broke. I can’t hear callers unless they are on speaker phone. They can hear me though. Siri doesn’t respond. The selfie camera doesn’t work. I think they are the only issues. What would the part be called that I need to buy to fix this?
After looking at the photo, it looks like the front camera / proximity sensor. Here is the replacement guide iPhone 6 Front-Facing Camera and Sensor Cable Replacement
new front camera by the sounds of it as it has the pads for the ear speaker
