Did Apple give me a new phone? Unfortunately no! I took my cracked screen iPhone 6 to this place and paid the price for fixing it. They tried but could not fix it and they gave me a "new" phone. I was so happy. It had a problem in one week and they gave me another "new" iPhone 6. That one also had some technical problems after around 6 months and they gave me another "new" iPhone 6. Yaaay! It had still warranty from the store. It had a problem again after around 9 months but it does not have warranty on it. I had just finished paying the phone in 18 months. I took it to this store again. They checked it and asked me $299 price to fix it. Nothing wrong about the screen but the phone was dead.
