Chosen Solution

Replaced iPhone 5 display assembly with home button and front camera. Everything appears to be working except the front camera. The camera opens, but when I try to flip to front camera it is a black image and the camera freezes. I have disassembled and reassembled several times and all cables “seem” to be secure, but I can’t figure out why the front camera won’t work. Any ideas would be much appreciated!

I would say you have damage the cable when transferring them to new screen A new camera will fix your problem
