I usually had great problems with my cellphones: dust. I keep my mobiles always in the pockets of my trousers. Most people don't, I guess, because no one ever confirmed to me they have the same problem: dust in the phone. So you'll have difficulties making pictures are reading the screen in daylight, for instance.Untill I had a great brainwave: waterproof means also dustproof! So when my provider offered a waterproof phone for free in combination with a cheap subscription, the deal was quickly made. Now I'm dustfree calling, textmessaging or internetting. It even has a flashlight!
