DONOT get your iPhone glass replaced at Cellteks. My wife took her iPhone to Cellteks to have her iPhone glass replaced. They charged $ 198 to replace the glass. They claim their after market glass is made at the same plant in China where they make the iPhones. Either they were told that and are gullible enough to believe it, or they are just lying. Apple has spent millions developing«Gorilla glass» and the last thing they are going to allow is for knockoff glass sellers to have their invention. Anyway, the glass they installed broke the TouchID sensor and at first they tried to excuse it away as not their fault. Then they finally replaced the glass again and miraculously it worked again. Within 48 hours the glass was broken AGAIN. That was not their fault, but the cheap glass they had installed was. We then found that Apple will replace the glass(with Gorilla glass) for $ 139. Do not pay pay Cellteks $ 198 for an inferior glass replacement. Lesson learned. Hope this can save someone else come time and money.
