Chosen Solution

My rear camera got shaky and would not focus. I replaced the camera, it works fine. Afterwards my earpiece and front camera would not work. I checked and double checked all the straps. All connected well, nothing damaged. Any ideas?

The ear speaker assembly is so fragile, there is probably damage caused that you can’t see. Replacement parts are really really cheap and luckily they aren’t paired to the phone like the new ones.
