On 3/19/16, I had my grandson's iPad Air broken screen replaced at the Wellington, FL franchise. A week or two later, the home button would not work (it was off center) so I took it to the Port St. Lucie, FL franchise. They said the first franchise had installed a defective screen (something about bad connectors) and replaced the screen and corrected the home button problem. On 4/17/16, the home button would not work again. I took it back to the Port St. Lucie franchise which corrected the home button problem and said they used a glue that hardens with UV light. On 4/18/16, my grandson discovered the home button would not work so I took it back to the PSL franchise on 4/19/16 (today). They said the repair tech who last applied glue to the button used too much glue on the center of the button so it did not harden. So they have the iPad again and are repairing it again. Hopefully they will do it right this time.
