iPhone 7 Plus - Front Camera + Proximity Sensor causing malfunctioning

Try new front camera flex

Thank you! I was so confused why it was so laggy and unresponsive when camera flux was plugged in. Camera flux cable was actually plugged in upside down so it wasn't functioning properly.

I have same problem with iPhone 7 Plus , when I connect the prolixity/ front camera , the home button and the audio stop working ; take few hours to find out that , I did not the flex cable correctly ( I putted in the other way ) just I changed the the position in the other direction and now working perfect

I found the fix! I had the same problem after screen replacement. My home button, front camera, and sound did not work. I tried buying a new ribbon and still no luck. I tried pushing harder on the connection of the camera ribbon and still the same issue. Finally I realized I had plugged it in upside down. Be careful it will click either way you plug it in. The ribbon should be going downwards when it’s plugged in, not toward the top of the phone. Simple mistake but the phone will assemble either way you plug it in. Good luck!

I have the same issue. First I was having issues with my microphone. It doesn't work at all. I can't use Siri, I can't talk on the phone, I can't record voice memos. Anyway I opened the phone to see if any ribbon cables we're disconnected or if something stood out but nothing. Upon closing the iphone back up it wouldn't turn on anymore. It's stuck on the Apple boot logo. I tried a restore and the restore was successful but still the iPhone is on boot logo loop. Does anyone else have an alternative solution? Ive been repairing iphones for a very long time and this has never happened before. Luckily it was my own phone I was working on this time and not a customer's phone. Any recommendations would be appreciated. Thanks.
