Also my phone won't shut off, it will only restart.

I can't find an iphone 5 case i like. What should I do?

I have an iphone 5 in white and since i've owned i can't find a case thats perfect. I've tried everything from an otterbox commuter to a clip-on hard plastic back case and nothing seems to do what I want it to. The case I had on my old 3gs was a switcheasy capsule rebel menace and it was perfect as it gave great protection, didn't cling to my pockets and was nice to use. Seeing as switcheasy didn't make a capsule rebel for iphone 5, it's left me jumping from case to case, I even tried an imitation capsule rebel case from china which also didn't work. I also have insurance on the phone. I was just wondering if anyone knows of any good cases for the iphone 5 or if i should throw caution to the wind and rely on my insurance? I also work at a golf course as a greenkeeper and it can get very dusty over there if this has any significance in deciding which case is best.

If it means anything, the charger port itself is cracked all the way down the inside leading to the iPhone. What's wrong with the case and how do I fix it without buying a whole new one?
