Asus ZenFone 4 and ZenFone 4 Pro (US)


Asus has launched three other new and unlocked smartphones in the US: ZenFone 4 Pro, ZenFone 4, and a 5.2-inch variant of the ZenFone 4 Max.

As its name suggests, the most advanced and most expensive new Asus phone is the ZenFone 4 Pro. Powered by Qualcomm's high-end Snapdragon 835 processor, this handset sports a 5.5-inch 1080p display, and has a dual (12 MP + 16 MP) rear camera with 2x optical zoom, optical image stabilization, and 4K video recording.

With the ZenFone 4 Pro, you're also getting 6 GB of RAM, 64 GB of expandable storage space, and a 3600 mAh battery with fast charging. The smartphone is sold for US$ 599, and should be available starting today via Asus, Amazon, Best Buy, B&H, and Newegg.


Also sporting a 5.5-inch 1080p display, the Asus ZenFone 4 is not as powerful as the Pro model, as it's relying on a mid-range Qualcomm Snapdragon 630 processor coupled with 4 GB of RAM. The ZenFone 4 has a dual rear camera, too, but this doesn't feature optical zoom, instead letting you shoot wide, 120-degree photos. Also on board are 64 GB of expandable storage space, and a 3300 mAh battery with fast charging. The ZenFone 4 costs US$ 399, being sold by Asus, Amazon, B&H, Best Buy, and Newegg.

Finally, the 5.2-inch Asus ZenFone 4 Max is offered for US$ 169 via Asus, as well as through all retailers mentioned above. The phone is basically the smaller brother of the previously released 5.5-inch ZenFone 4 Max, so it's got similar features, with a few differences - 4100 mAh battery (instead of 5000 mAh), a Snapdragon 425 CPU (instead of 430), and 2 GB of RAM plus 16 GB of storage space (instead of 3 GB plus 32 GB).

All of Asus' new smartphones have dual SIM support and fingerprint scanners, being compatible only with GSM/LTE carriers like AT&T, T-Mobile, Cricket, MetroPCS, and so on (Verizon, Sprint, and US Cellular are not supported). The handsets run Android Nougat out of the box, with Asus' own Zen UI 4.0 on top. We're certainly hoping to see Android 8 Oreo updates arriving soon.
