Yes, to be honest, I am hesitant because I have read this forum and seen the issues people are coping with that I am not with this device. But I have decided it isn't normal and that if dust is getting in after 2 weeks of use then what would it look like after a year? The strange thing is that in daylight, I can only see about 3 or so of those dust particles. In the house under a lamp with the phone held at certain angles I saw what looked like dozens of them.
I can and will exchange it for a new device tomorrow at the store I bought it from, which has a 60 day return policy. Let's hope I get a device as good as this one but without the proneness to particle invasion.
I am thinking you new device will be just fine. I would do a good backup though iTunes before turning your phone in.
Good luck and have a great weekend!
