Problem with 3G coverage over 900mhz

Hello

I've have a problem with my Note 3.
It does not connect to 3g network 900 mhz i think. In the same area i've tested ipad air 2, iphone 5s and a Doro phone all all those have the same carrier and have 3g coverage, but not my Note 3.

My Note 3 works fine on 4g and 3g/H in the city, but not where i live. I've been in contact with my carrier and Samsung, they all say it should work, but it does not work. I've also got a new sim card from my carrier, same problem. Only Edge coverage where the other phones get 3G.

Im not 100% sure about what frequency they use, but maybe someone have an app for the note 3 so see what it is connected to.
Maybe try to find the same app for apple and see what frequency they connect and get 3g coverage over.

Dust Under Glass Over Camera

I've had this phone for about three weeks and after around two weeks, I noticed that the pictures were starting to come out fuzzy and overexposed looking. Finally realized that there was dust under the glass covering the camera lens. Unfortunately, since it's under the glass, I'd have to take it apart to clean it (or possibly send it to Amazon for warranty, if they cover it).

The issue is that even if I take it apart and clean it, the issue will come up again and I'd rather not have to constantly take it apart and clean (especially since it happened only after two weeks). Does anyone have any suggestion to prevent this from happening again, besides not keeping it in my pocket?

This seems like a poor quality design to me. I carried my previous phone in my pocket for four years without any issues.

Thanks.
