Update: ZTE Axon 7 is getting Android 7.0 Nougat, but the official release date has been delayed due to quality standards. Here's our review of the phone in its current software iteration as well as a ZTE Axon 7 Mini review.
The Chinese phone-maker is ambitiously trying to compete with the top phone manufacturers from the US and South Korea, so much so that it designed the phone outside of China, in the US.
What we end up with is an Android Marshmallow smartphone with a polished metal design, rich-looking Quad HD display, booming front-facing speakers, and a load of software customizations of the kind often found in a more expensive handset.
That's not all. It won't be long before the Axon 7 is updated to Android Nougat, and ZTE is touting it as the first phone compatible with Google Daydream VR, which is technically true – we're just waiting for Android 7.1 Nougat, which debuted with the Google Pixel, Google Pixel XL and Google DayDream View VR headset, to make that happen.
Release date and price
The ZTE Axon 7 release date was July 27 in the US, it came to the UK and the rest of Europe in September, and finally launched in Australia in late November. You just won't find it everywhere, including in US carrier stores.
You have to buy this phone unlocked on Amazon or another retailer and pay full price. It won't be sold at US carriers like AT&T, T-Mobile, Verizon or Sprint and you shouldn't expect price subsidies.
While it technically has enough bands to support all US phone networks, it only works with AT&T and T-Mobile nanoSIM cards right now. Verizon and Sprint compatibility is due "possibly later in the year", essentially requiring the two CDMA carriers to flip a switch. All of the antennas are inside – this isn't just a GSM phone.
The good news here is that if it works with your carrier, the ZTE Axon 7 is available at an attractive price. Packed with 64GB of internal storage it costs $399 (£359, AU$699). Plus, you won't have to deal with a pesky two-year (or any) contract or carrier app bloatware for that price.
There's also a 128GB ZTE Axon 7, which includes the company's own take on a Force Touch display, an always-on screen and 6GB of RAM – which makes it potentially faster than the Samsung Galaxy S7 and S7 Edge – but we'll have to see if that one ever makes it out of China; there's no price or availability information for Western markets yet.
All of this contrasts with the 32GB Samsung Galaxy S7 unlocked at $669 (£569, AU$1,148) and the 32GB iPhone 7 at $649 (£599, AU$1,079); note that both these phones have smaller screens and half the internal storage space.
The ZTE Axon 7 feels like the grown-up version of last year's ZTE Axon Pro thanks to its all-metal design, and it's considerably less chunky. It looks and feels ready to compete with Samsung, LG and Apple.
You can hold it in one hand, but with palm-stretching dimensions of 151.8mm x 75mm x 7.8mm and a slippery aluminum design, you'll find yourself struggling to reach for the corners without using two hands.
Handily, there's an ultra-thin silicone case included in the box, along with standard earbuds and a USB-C-to-micro USB adapter. The clear case makes the phone grippable without seriously detracting from the stylish metal design or matte gold color.
What ZTE has done nicely on the front of the Axon 7 is maximize the real estate for its 5.5-inch 2K display, with a virtually edge-to-edge screen and an overall minimalist look.
The front of the phone is also home to awesome-sounding dual front-facing speakers, a small front-facing camera, and three out-of-the-way capacitive buttons.
These always-present yet subtle buttons are an improvement over ZTE's original on-screen buttons, which vanished to enable the display to go 'full screen' in certain scenarios (usually right when you wanted to hit the back button).
The small capacitive buttons are also a better use of space than going to the other extreme; the Moto Z , for example, makes room for a larger-than-necessary chin that includes a Moto logo, a fingerprint sensor and on-screen buttons, with the result that there's too much bottom bezel and not enough screen.
Our only complaint is that we wish these tiny buttons lit up for easier night-time use – your brain will have to adjust to memorizing their location.
You won't find a fingerprint-sensing home button taking up space on the front here. Instead, the biometric sensor is elegantly embossed on the back.
It's easy to reach the fingerprint sensor on a phone of this size (easier than we found it to be on the taller Nexus 6P), and the one on the Axon 7 is just as fast and accurate as those on competing top-end handsets (ZTE uses the same Swedish sensor supplier, Fingerprint Cards, as other leading brands).
ZTE has also resisted the temptation to stamp its logo on the front of the device, favoring the back for splashing its name, which creates a cleaner look all around.
At the moment Ion Gold is the only color option for the ZTE Axon 7, and the included earbuds have a matching gold trim. The company plans to add a Quartz Silver color, too, but this isn't available at launch.
The ZTE Axon 7's display is 5.5 inches, with a 2560 x 1440p quad HD resolution. It's the same resolution as last year's Axon, but the important difference here is that it's an AMOLED display instead of an LCD.
That may not seem like a big deal at first, but the colors really pop on this screen, and the Axon 7 also has improved battery life as a result of the change.
The Quad HD display shines brightly (even outdoors) once it's on, but ZTE hasn't gone as far as to include an always-on screen on the Axon 7 with 4GB of RAM, as we have seen with the Samsung Galaxy S7 and LG G5.
We've learned that ZTE is saving this display feature (along with its version of Force Touch) for the souped-up 6GB of RAM version of the phone – as mentioned, this more powerful phone hasn't show, its always-lit face just yet.
The Axon 7 screen is really being set up to not only look good on the phone, but to support VR. Really, that's the only reason to make displays of this size go from 1080p to Quad HD in our opinion – when it's that close to your face, then the higher resolution matters.
Not surprisingly there's an 'inexpensive' (though no price has been announced yet) ZTE VR headset coming. It's another Samsung Gear VR clone, like the Huawei VR headset, but it's been future-proofed for Google Daydream.
It also doesn't hurt that ZTE has put together a nice selection of wallpaper that really lets the lock screen show what the display is capable of – it's scrollable and randomized by default.
We really can't understand why phone-makers stop short of presenting a vibrant set of default wallpapers when you first boot up a handset's 2K display (read: the LG G5's sickly green gradient). ZTE sells itself better from the get-go.
A smaller, but still noteworthy display upgrade comes in the form of Gorilla Glass 4, rather than Gorilla Glass 3. It's not quite as durable as Gorilla Glass 5, or shatter-resistant like the Moto Z Force, but you'll appreciate it if (admit it: when) you drop your new phone.
