Just bought an iphone 8 plus for cheap with the brocken back glass being the only issue. Im not super advanced but Ive done lots of phpne repairs myself and felt pretty confidentabout replacing the glass only myself until watching some videos and people warning you can completely mess the phone up? Is it worth it? What things do I need to look out for if attempted? I would just throw a case on it but a good amount of glass is alreasy missing from it.
