There are a lot of mobile techs our their that do not have the training to repair your devices properly. I have a guy that works in west Cobb that repairs iPhone ,iPod, and iPad He is only a YouTube tech and lacks the experience to repair your device beyond the simple screen replacement and even then he has messed up some peoples devices and had to bring them to me to fix. So what I am saying make sure your tech that is repairing your device has the proper experience to repair it. I have even checked the guys site that show pictures of his repairs and just by looking at the photo he is showing to you I can see he broke the customers wi-fi cable and had to replace it on the iPad from his Facebook page. He even brought to my shop an iPod that he ripped the volume flex cable off the board and I had to re-solder on a new one for him, but that's not the only thing he used a metal object to separate the board scraping off the protect elements on the board and exposing the copper under it. Do you really want that guy repairing your device?
