Description

Asus has once again made the curious decision to bury its highest-specced smartphone behind a derivative name: last year we had the ZenFone 3 Deluxe, and now there's the ZenFone 4 Pro. But while its moniker might suggest otherwise, the device is actually quite an interesting one: it's powered by Qualcomm's Snapdragon 835, coupled with 6 GB of RAM and an impressive 3,6000 mAh battery. But the highlight of the device is most definitely its rear cameras: 12 MP shooter with optical iamge stabilization and PDAF, and a second 16-megapixels sensor for 2x optical zoom.

This device is also known as Asus ZS551KL
