iPhone 7 Plus freaks out after Front Camera/sensor flex replacement

Hey guys!

I really need a good idea. I replaced my screen four weeks ago and it was successfull - instead of I accidently damaged my front camera/Sensor cable. Sensor and speaker had no function anymore, only the Camera worked. Also the rest of the phone was fine.

So I ordered a new flex cable, installed it and suddenly the iPhone freaked out much. Booting needs minutes, if I clicked on an icon it needs 20 seconds until it recognizes the click and sound was not working completely. "Funny" thing: If I still opened an App all was working fast and normally as long I was inside it. Also the home screen worked fast (sliding left/right through the pages) until I did not click on a folder or app, then it freezed and needed a long time to open it.

So I removed the cable again but the issue was the same without it. With the old cable: same issue. Then I reseated the original cable several times and suddenly all was working great and the freezing was gone - instead of the speaker and sensor after I damaged both originally.

So I first though the issue was related to the new cable, I gave it back and bought a new one. And after I build that In I got the exact same issue. Slow boot, slow responses while clicking on an app... But this time I was not able to solve it somehow like I did it at the first try. I also found out the microphone and speaker (both) are not working, if I try to play something which has sound (video, music) the iPhone freaks out, crashes or shows a strange Apple Music issue. Headphones are also not detected. If I try to start a audio message in WhatsApp it also stucks at 0 seconds. But instead of that - plus some sporadic short freezes inside apps - the phone works so far.

Overall I am at the end of my ideas what the issue could be or was causes from, especially after I was able to fix it at the first repair. Did anyone had a similar issue and was able to solve it?

Many thanks!

If I remember correctly the cable folds / flips and plugs into logic board. There is a chance you may be plugging it upside down.

Having the front camera cable plugged upside down is very dangerous. It can kill home button functionality and can even cause the phone to die.

The iPhone 7 guide on here should show an image of how it should be originally plugged in.

Yes, the cable was correctly connected before I reconnect the battery-cable or turned the phone on. I also noticed now that the vibration motor is not working too.

I am very confused what I did at least as the issue occurred the first time where I was able to fix the issue. The problem came back at the moment I connected the new flex...


Ah, and by the way: The home button works fine with all functionalities. Fingerprint, klicking - all is working properly.
