Was led to think this case is dust proof, not the case at all the problem lies with the screen cover, it gets dirt, dust, stuck between the case cover and the screen of the phone. You have to clean it consistently. Very poor design.
The case provides excellent protection, but the corners of the rubber outer case started bagging out and getting loose before the case was a month old. that is very disappointing. sent for a replacement which was no problem, but I don't want to have to replace it every month. otterbox needs to get longer lasting materials for the rubber part.
