It is one of the best mobiles I have ever used but it lacks many features like NFC, even though the company say it is 21 mega pixel the camera is not upto the mark. It can handle high end games pretty easy and do no heats a lot.The charging speed is so awesome and I wish there was wireless charging.The could have included headphone jack and external memory card slot.The microphone is so awesome and I loved it a lot , also the 4G speed is so good. The best thing I loved is its unibody metallic design and the vibrant diplay which is 2K. Am satisfied with this phone and I recommented it to everyone in my family and friends.
