This is a very cool phone taking about merits : -
1) 6 gb ram with powerful snapdragon 820 will enable you a new gaming experince
2) Physical design and look of the phone is professional
3) Have a very excellent camera specially rear camera 16 mp
4) Fingureprint sensor is very accurate and fast
5) Phone is slim and light weighted

7) Full hd phone
It also have some demerit : -
