The Asus Zenfone 4 is the smallest and most affordable member of the new Zenfone lineup. It comes with a 4″ WVGA IPS display and runs on a dual-core Intel Atom Z2520 1.2GHz processor. The rest of the specs include PowerVR SGX 544MP2 graphics, 1GB of RAM, 4GB of expandable storage and Android 4.3 Jelly Bean. Asus says the phone will be launching with Android 4.3 Jelly Bean but will be getting KitKat shortly after.
The Zenfone 4 is made entirely of matte plastic and is a bit thicker compared to its siblings. It is a dual-SIM device with a snappy chipset at a bargain price, so we are ready to forgive it the extra few millimeters around the waiste.
The entire front is occupied by the 4.0-inch IPS WVGA display with the typical Android capacitive controls below. The lonely camera lens is on the matte black, there is no LED flash.
The battery cover is removable and you can access the two SIM beds, the microSD slot and the battery whenever you want. In case you don't like the black flavor, Asus will be offering white, red, blue and yellow colors as well.
The right side of the Asus Zenfone 4 has the glossy Power/Lock key and the volume rocker, while the left one houses the microUSB connectivity/charging port.
The 3.5mm audio jack is on top of the Zenfone 4, while the microphone pinhole is the only thing of interest at the bottom of the device.
The smartphone should cost just $99 SIM free and should launch in the coming months.
