So I have had my iPhone 6S for one month. Last Friday, I had it in my back pocket while I was helping a customer at work. I had to sit on the ground, and I forgot it was there so needless to say the entire screen was busted. I've had an iPhone for years, and this is my first cracked screen. Anyway, I went to the Apple Store, and since they don't have replacement screens, they gave me a new phone for the same price as a replacement screen. I was happy about that, but not so my stupidity. Anyway, my question is what type of case (brand, etc.) do you all use? I've also noticed this new one they gave me that certain apps crash or not even open at all. My broken one never did this. Is this a hardware or iOS 9 problem? Do you think the screen is less durable on the newest model? My old 5S I dropped lots of times, and I never had one cracked screen even though some of them I was worried when I picked it up. Thanks!
