It comes with 2gb ram and 8 gb rom which is enough. It does not lag at all. It has android lolipop with an update to android marshmallo. It has 8 mp primary camera with great resolutions and 5 mp secondary camera. It is a low budget full featured smartphone with amoled display. I loved its new look and notification light at back around the camera which you can set for 4 different colours. It is an amazing phone with great speed and relability. So just go for it.
