Month, the Zenfone 4, Zenfone 5 and Zenfone 6. Despite the naming scheme, these are not the same device with different screen sizes. The sizes correspond to significant differences in price and capabilities.
Each of the three has its niche, and the Zenfone 4 is aimed squarely at capturing the bottom end of the smartphone market. Asus has its sights on first-time Android buyers who represent a massive opportunity for smartphone vendors.
There are two versions of the Zenfone 4 - the A400CG model which we have in for review today has a 4-inch screen and a 5-megapixel camera, whereas the A450CG, which hasn't launched here yet, has a 4.5-inch screen and 8-megapixel camera. Most other specifications are the same.
We were pretty impressed by the Zenfo
