The rear and front camera isn't working, flashlight won't work too.
I just replaced the screen in my IPhone 6s Plus, I also replaced the rear camera lens, just the glass part. Now both the front and rear camera won't work. I did have the battery disconnected and all power drained from the motherboard (I held the power button for 30 Secs.) this has never happened to me before and I have replaced several screens. Thank you for the help!
Is this a good question?
