I have only had my iPhone 6 for a couple of months, I have already gone through four different iPhones, my first one had black specks behind the screen, which I went to Apple and they didn't know what they were and they seemed to get bigger every time you'd touch them. My second one was a refurbished one but was never fixed properly, it overheated and could not hold a charge. My third one had a black screen and had to do a hard reset to fix the problem, which ended up happening again. I would like to get away from iPhones, how would I go about doing so. I do not want to pay for it if I am constantly getting phones with problems.
