So, my wife dropped her iPhone 5s the other day. It was in a case, and dropped about three feet onto the ground, but when she picked it up there were vertical bars on half the screen. Also, that portion of the screen became unresponsive. There was no physical damage to the exterior of the phone. I didn't think the phone should have broke after such a light fall, I mean, we're not talking about throwing it off a sky scraper, but a little drop from hip level, with a case. Still, I went to the Apple store prepared to pay for an out of warranty replacement, since I figured they would use the fact that she dropped it as an excuse to void the warranty. However, when I went in the genius didn't even ask me any questions. After I showed him the phone, he examined it for exterior damage, checked for liquid damage, and just came out and said " let me get you a replacement", free of charge. Whole thing took about 5 minutes. Way to go Apple! I know my carrier would have tried to charge me full price for a replacement. I've never had an android or windows phone, but I wonder what those folks do if their phone breaks? I have a sneaking suspicion that it's in not as easy or as free to get replacements or service on other brands phones. Just another reason I choose apple products.
