Ummmm, 7th or 8th "bad" drop, plus lots of "good" drops? In all the years I've had a mobile phone, you can count the number of total drops on one hand, with some fingers missing. It just sounds to me like you are clumsy, and if you can't be bothered to protect your phone from your own negligence, what do you want people here to do about it?
People arguing that using glass is a flawed design seem to be misreading the situation. YOU bought the phone, nobody forced you. You KNEW it has glass on the front and rear, so the only flaw here is your own decision to buy the phone in the first place. Fact is, you bought it because it's by Apple and it looks good. So, you have absolutely ZERO right to complain about the materials used in its construction.
Buy an iPhone, don't buy an iPhone, buy a case, don't buy a case...make your own decisions and stand by your own actions and negligence rather than trying to pass the effort and blame onto others.
