Asus Zenfone 2 ZE551ML Review: Gets the Basics Right

By on Email @exolete

The Asus Zenfone 2 ZE551ML was the first phone to come with 4GB RAM. Even if you forget that for a moment, it packs a 5.5-inch 1080p IPS display with Corning Gorilla Glass 3, Intel's latest quad-core 64-bit processor (Z3580/Z3560) with 4G LTE support, 13MP/5MP Cameras running Android Lollipop with ZEN UI on top. We reviewed the 2GB RAM variant of the Zenfone 2 ZE551ML with 1080p display and found it to perform quite well. Multitasking was no issue with the device. The placement of the volume rocker at the back is not ideal and the power button up top is a huge design mistake from an ergonomic standpoint. But at its price, the Zenfone 2 is still good value for money given its build and performance.
