Asus zenfone 2 is the best android phone i’ve came across. The back cover is smooth and the display has vibrant color. It has everything a heavy user is looking for. High RAM and internal storage space. It is strudy so you need worry of the cell being damaged easily.
It has its own unique UI and just love the notification panel. Scroll down from right, displays various toggle and scroll left, displays notification panel. Phone worth buying.
