All you need to know about Asus ZenFone 2

Asus has finally launched the world's first smartphone with 4 GB RAM, ZenFone 2, priced at Rs 19,999 for the 32 GB variant.

ZenFone 2 has a 5.5-inch Gorilla Glass 3 display with good touch response.

For photography, Asus has added a 13 MP rear camera. The images captured in bright daylight are impressive, but some shots are overexposed.

Asus has added Zen UI to this phone, instead of the plain vanilla Android UI. ZenFone 2 handles basic stuff, such as fetching emails, multi-tab browsing, downloading apps, etc. with ease. It has sleek edges and a slightly thick rear that looks good in metallic finish.

However, the battery is a letdown; it won't even last a day if you are a heavy user.
