I've had my iPhone 5 since approximately 2 weeks following the release of the iPhone 6 and just a week and a half ago my screen started separating from the chassis and the chassis is cracked right at the volume down button. Now here's the history of my device it's a 2nd gen hand-me-down; my father purchased it on release day, passed it on to his wife at the release of the 5S, and then made sure it was passed on to me at the release of the 6 and 6 Plus. Now my father and his wife have never been ones to purchase protective cases for their apple products, because they take such good care of their phones, so much so that I received my device in the original box it came in with all of the original cords, cables, booklet, headphones and even the stickers, still sealed in their original packaging, and the phone itself in a clear dust cover bumper case that you can purchase for $5 from Apple.com. Now me I'm s bit on the clumsy side, I dropped my iPhone 4s the day I received it last year and broke the limited edition Steve jobs memorial glass my father had installed, so my first action upon receiving this new, to me anyways, phone was to purchase an otter box defender series and make sure it was properly installed. I achieved this goal simply enough and my phone remained in that case until a week and a half ago when I purchased a shatterproof screen protector for extra measure, lo and behold when I removed my phone from its case I was shocked to find it was bent the top right corner of my screen was separating from the chassis and there was a chip at the volume down button. Yes, I'll admit my phone has taken a few spills from tabletop to floor, but nothing to warrant the separation of screen and chassis and definitely nothing to cause the crack, screen side, next to the volume down button. I noticed though that my phone was hot, not warm, but actually hot, so much that it burned my hand, almost causing me to drop the phone, unprotected, on to the floor. I've since conversed with my father and he's unsure of the cause, but I'm beginning to believe that the otter box's insulation caused my phone to rapidly overheat, thus causing the aforementioned damages.
