This is the best Android phone I’ve used so far. The design is just laudable, it doesn’t feel big for a 5-incher phone. It is light and thin. The Air gestures and Air view work pretty well and are useful for me. Its screen is one of the best displays out there with very good color rendering, deep blacks and with wide contrast ratio. The 13MP camera is noteworthy. However I can still see room for improvements for UI optimization. The software is just too big that it occupies almost half of the internal memory for the 16GB version. Overall, this is a very powerful phone and is worth the upgrade.
