This phone is a flagship phone. Its build quality is very good and a great form factor in holding and a premium finish. 5.5 inches screen makes it difficult to use with one hand.
But usage vary with people if you need a customizable UI and oths fer things this phone is for you.its camera is good but not very good, low light stills are also fine.If u are a camera concerned person this is not for you. Sound quality is good. viewing angles are also good.
Its a unibody handset, frame is of metal and back is metal finish type in grey model.
Overall phone is good .but according to your need u can choose the device.
