You should also buy a glass screen protector for it. I bought one and have dropped my iPhone a few times and the protector cracked and chipped but the screen underneath is fine. I'm also going to buy the lifeproof case. It might be a little pricey but is totally worth every bit of money.
I actually just bought an otterbox commuter for my s4 today because I keep dropping it & my husband will kill me if I break it since I just broke one in February lol
