What the Critics Are Saying...

If the “bezel-less” look isn’t your thing, but you still want flagship speed and a refined look, then the Zenfone 4 Pro is there for you, but for $600, it's a tougher sell given the camera performance and underwhelming display brightness.

ASUS’s glass smartphone is fragile yet powerful, with a long-lasting battery.
