Asus made quite a splash by launching three new phones this 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.
The Asus Zenfone 4 is the smallest and the cheapest smartphone in the Zenfone family, sporting a 4-inch display. The middle sibling in the family – the Zenfone 5 is one of the best mid-range smartphones we’ve tested, giving the Moto G (first gen) a run for its money. Does the Zenfone 4 put up the same show in the budget category? Read our detailed review to find out.
The Asus Zenfone 4 has a 4-inch display wrapped in a rectangular curved-edged body. This makes it easy to use one handed and the ergonomically-placed buttons are easy to reach. The removable plastic back cover has a chalky matte finish, while the volume and power buttons are metallic with concentric circles. As with all the phones in the Zenfone range, there’s a shiny strip at the bottom of the phone, which in this case is made of plastic. The phone weighs 115g and feels solid. Despite the budget price, the phone looks pretty stylish and sturdy in construction.
Display
The Zenfone 4 features a bright 4-inch, 480 x 800 resolution display with a layer of Corning Gorilla Glass 3, which should make it resilient to scratches and minor knocks and bumps. While the screen is fine for those who intend to use it for basic tasks of calling and sending text messages, the low resolution means it’s not suitable for gaming and watching videos as the screen suffers from reflections and poor viewing angles. It’s almost impossible to see the screen clearly in bright outdoors.
Asus packs the Splendid app, which helps you enhance the display quality to an extent. But even the app does little to improve the viewing-angle problem.
