This is an awesome phone.

Camera quality is best among all the smart phones out there(except lumia 925/920 & 1020). It’s even better than Xperia Z1 which has 20MP cam.
Performance - It’s flawless, Blessed with new snapdragon 800 processor. This phone has topped almost all the benchmarks.
Screen - one word - "PERFECT", It has got a screen size of 5.2 inch. In a body of size smaller than that of Xperia z1(which has 5 inch display). Also it is IPS display, so very bright. Very comfortable even in Sun light.
Weight: Super light for it’s size. After using it, Xperia z1 feels heavy like a rock.
