I changed the screen and front camera in an iPhone 8 plus but now both cameras are just black and the wifi seems to be a bit temperamental, what could the problem be?
You could’ve damaged components on the board while performing the repair. But before we get to that, inspect the thin ribbon cables and the connectors to make sure they’re not damaged. When you replaced the screen, did you buy one with the front camera already installed, or did you transfer that over? Posting pictures of the components would be greatly appreciated!
