So I own a black 1520 which I've always used in an amzer tpu case or the incipio Ngp. I noticed after taking it out, it was all scratched up and had white nicks and scratches from stuff getting into the case. Luckily the phone is defective so I have a nice red one coming in and don't want to have the same happen to it. For work I deal with very dusty environments so I'm looking for something to prevent it from getting in. Suggestions? I wish otter box made cases for it but that thing would be a tank!
