It has been a long wait and ASUS has finally taken the wraps of its Zenfone 4 series. If you know ASUS, you should know that they love releasing multiple variants of their phones. This year is no different as there are 6 different variants of the Zenfone 4.
ASUS not only released new phones, it also announced ZenUI 4.0, the latest iteration of its own custom version of Android.
ASUS Zenfone 4 Pro
The Zenfone 4 Pro is the leader of the pack. It is ASUS’ flagship of the year and we are happy it doesn’t disappoint.
The phone like most flagships has a metal and glass design. There is 2.5D glass on the front and back and a metal frame in-between. ASUS is still in the bezel business so expect it to be bigger than the LG G6 and Samsung Galaxy S8.
The Zenfone 4 Pro packs a 5.5-inch Full HD AMOLED with ASUS’ Tru2Life technology. It is powered by the Snapdragon 835 and packs 6GB of LPDDR4X RAM. Built-in storage is 64GB with the option for expansion via a microSD card slot (2TB max).
ASUS will probably get the award for the flagship with the largest battery as the Zenfone 4 Pro has a 3600mAh battery. It is also just 7.6mm thick. There is NFC and a fingerprint scanner buried under the rectangular home button. You also get an audio jack positioned at the bottom of the phone, a USB type-C port , dual speakers and a FM Radio.
The Zenfone 4 Pro has Bluetooth 5.0,WiFi a/b/g/n/ac and GPS. There will be a Taiwanese/global variant, a North American/UK variant and a Japanese/Indian variant with varying band support.
It will run Android 7.1.1 Nougat out of the box.

The large aperture of the main camera isn’t the only cool thing about it. ASUS says it has a triple focus system. In addition to the original contrast focus, there is laser focus and a dual-pixel phase detection autofocus that works in conjunction with the four-axis OIS and three-axis EIS and an RGB light sensor for better images. The front camera is an 8MP sensor.
ASUS camera software, PixelMaster has been bumped to 4.0 and brings features like time lapse with power saving, slow motion, and ultra-high resolution images up to 48MP.
