What the Critics Are Saying...


Photography Blog

Asus might not be the first name that you think of when buying a new smartphone, and its mid-range price perhaps leads you to expect a solid device, rather than spectacular one, but the Zenfone 4 certainly offers a lot of photographer-friendly features that are well-thought-out and well implemented.

- Mark Goldstein, Photography Blog
Mobile Syrup

The ZenFone 4 marks yet another quality addition to Asus’s ZenFone line. While its lack of carrier support may mean it’s destined to remain an obscure brand for most consumers, those seeking quality inexpensive options online would do well to consider this handset.

- Rose Behar, Mobile Syrup
Digital Trends

Good audio performance can’t rescue the ZenFone 4 from its frustrating software.

- Andy Boxall, Digital Trends
Know Your Mobile

A nice overall package with a great mid-range spec. Unfortunately costs a bit too much and the camera is a bit temperamental

- Paul Briden, Know Your Mobile
Coolsmartphone

It is a fantastic handset and priced well considering the quality and speed of it.
