I am using this device for a month. I can say Z5 is a very useful and powerful device that looks and feels good on the hand. I switched from IOS to Sony and haven’t missed IOS yet.It has strong visual and audio capabilities, sufficient battery life, very good camera, fast processors. One of the best smart phones in the market.Awesome battery life, waterproof capabilities, light Xperia skin, thin body, beautiful screen ( 2k is not needed and kills battery life IMO) . I suggest this phone is awesome
