"iPhone 6s Camera cannot focus and loads of other issue"에 답변TLDR; If you do a housing swap on the 6s make sure you put the grounding bracket part in the new housing or the camera won’t focus. I have solved the issue in my iPhone 6s the camera not focusing after a Housing swap. The way I solved it is that I noticed that the new housing did not come with this bracket and I didn’t swap it since I thought it was just for protection purposes, but it turns out it is the grounding for the Focus voltage rail.
"Camera won't focus properly, especially close up!"에 답변Where you able to fix it?? I have the same problem on a 6S on ios 13
"iPhone 7 NFC(Apple Pay) not working after battery replacement"에 답변For an iPhone 7 (4.7 inch) model, something that is NOT in the teardown guide is that this little part is the NFC antenna. I accidentally stripped the new housing screw hole during a housing replacement, and after that Apple Pay and NFC stopped working. After several days of trying to get the Standoff screw to tie, I finally decided to put a small rubber pad on top of the Frontfacing camera shield on the board so it will be pressing down with the Display. Not expecting much, I checked Apple Pay and voilá! it worked! (Over the screw on the right) So TLDR; Do not damage the Standoff screw or the flex, that’s the NFC antenna. Had to jimmyrig it to work after I blew it.
