This phone is amazing, but sadly mine had the camera broken (not working or dead) and I had to replace it. It's unbelivable than a new phone has this kind of issue, plus the international guarantee is not usable in all countries (Costa Rica for example) I couldn't use it because I didn't made the purchase on the country... Samsung your doing it wrong!
About Tech Giant I liked that they send me the package before than I espected. The customer service is excellent they contact you very soon, they are very kind and tries to solve any problem you need to. In my case they helped me with my camera's problem.
