Replaced charge port and phone does not pick up signal.
I recently replaced the screen on my s7 edge but damaged the back button light. I ordered a couple charge ports and upon installation it does not pick up any phone signal. I put back the old charge port and it picks up signal right away. Everything is connected properly and also, I did order the correct model. I went through a dozen charge port and some would pick up signal but it would go out later. Just the original charge port will pick up signal and not drop. Can someone tell me what is wrong?
