What I can say in general use after a week: Great phone, super fast, great service, beautiful design, lots of useful features (all Air features like AirView, AirBrowse and smart features like Smar Scroll, Smart Pause and energy saving modes). Everything great. What bothers me personally strongly: Point 1: The battery life is average. When you play a game, WhatsApp and Instagram used the cell phone holds by just 10 hours. For other devices this is much better. However, the term may be extended by the power saving .. Although I would apply the ultra-power-saving mode only in emergencies. A Travel Charger I probably still grow me. (I prefer here, however, no star off because this could also be one of my usage.) Point 2: front camera! This is just awful. In my S3 it was definitely better, the S5 it is about the quality of the front camera of the iPhone 4! Total pixelated, not nice. And a big step back.
