ZTE Axon M review

That said, the design has its downsides… 

The phone is both thick and heavy. Many reviewers likened it to holding a deck of cards. Also, since there are screens on both side of the phone, finding a compatible case is next to impossible. 

Lastly, while you can unfold the phone and span content across both screens, this creates a 10.4-inch square display, not a larger rectangle display. So for most content, you’re almost getting more black bars than added space.

The phone uses a 2.15Ghz quad-core Snapdragon 821 with 4GB of RAM. Reviewers had no problem launching two apps or a game and a movie at the same time using each display. The processor had no problem keeping up, and the experience remained fluid -- even when reviewers pushed the phone to its limits.

You’ll find a generous 64GB of internal storage for your favorite apps, games, and media. Support for microSD cards up to 256GB means you can expand anytime.

Software changes are minimal, with a few extra buttons and settings to account for the dual displays. Otherwise, you’re greeted with a stock Android 7.1.2 interface and features. ZTE planned support for Android 8.0 -- however, exact dates are unavailable.

The camera was a major point of contention among reviewers. The phone sports a single 20MP rear camera. There is no dedicated front lens. If you want to use video chat or take selfies, you’ll need to be sure you’re facing the correct display and use the software to trigger the camera.

Reviewers found this approach clunky and confusing. 

However, once they got the camera running the way they wanted, they captured decent pictures. Low-light performance is only so-so, but still acceptable for quick snaps or social sharing images. 

With two screens, the 3180mAh battery has quite a range of run times. In single display mode, reviewers had no trouble hitting a full day on a single charge. With both displays running resource-intensive apps, the battery died in roughly 2 hours. 

Charging speed was decent, with a full charge taking around 1.5 hours. However, if you’re planning on using the dual display features often, you’ll want to keep a charger nearby.

Reviews on the phone are mixed overall -- mostly revolving around the design. This isn’t a slim, trim, flagship device. And if you don’t have an interest in dual displays, there are cheaper single screen options with similar specs. 

TechRadar summed up opinions well, saying, “The Axon M is obviously a niche device, and to that niche it delivers something special in a surprisingly polished manner.” Gear Diary was less positive with their verdict, stating, “... as a proof of concept, the ZTE Axon M is fascinating, but it’s too small and too limited by the lack of third-party software to truly be a daily driver.”
