[COLOR=2B2D32]The Axon 7's design is the result of a team up between ZTE and BMW DesignWorks, and it's a definite improvement over its predecessor. My gold review unit has a smooth matte finish on its metal body that helps it reject fingerprints and is accented by eye-catching glossy chrome edges that are also around the camera and recessed fingerprint sensor. It looks and feels gorgeous in an elegant way that upstages the OnePlus 3.[/COLOR]
[COLOR=2B2D32]Just like its predecessor, the Axon 7 has a row of dot cutouts on the top and bottom of its front face, but unlike the Pro, these grilles actually hide speakers. (The old Axon's grilles misled a lot of people into thinking it had dual speakers, but it only had one.) Below the display are capacitive keys for Back, Home and All Apps. There's also a dual SIM card slot on the left edge -- a welcome feature for frequent travelers.[/COLOR]
[COLOR=2B2D32]ZTE says the Axon 7 will eventually be ready for Google's "Daydream" mobile VR platform, and its display certainly seems prepared for the task. The 5.5-inch Quad HD AMOLED screen was a great canvas for my Netflix binging and Instagram sprees, but it was unfortunately dim in sunlight. Although it doesn't fix the lack of brightness, the Axon offers built-in software that lets you customize the display's color output. The tool lets you pick from three saturation profiles -- "Natural," "Colorful" and "Gorgeous" -- as well as "Warm," "Normal" and "Cool" color temperatures. I set the screen to "Gorgeous" and "Normal," which delivered higher contrast levels and deeper hues.[/COLOR]
[COLOR=2B2D32]Complementing the screen is a HiFi audio setup. Not many smartphone makers pay attention to quality sound, but ZTE is so proud of its system that it devoted six pages out of a 33-page reviewer's guide to it. The only other component that got as much love was the camera. For the most part, the coverage was justified.[/COLOR]
[COLOR=2B2D32]The Axon's dual front-facing stereo speakers pumped out distinct, clear sound that drowned out my laptop's speakers while both devices were set to their maximum volumes. The phone's speakers were so clear, in fact, that I could easily hear the crinkling of wrapping paper in the background of a scene over dialogue and overlapping music. The Axon was also loud enough to hear from another room. Dolby Atmos enhancements created a surround sound that is more immersive than I've experienced on other devices. One of the few other phones to place such a heavy emphasis on audio is the HTC 10, which lets you tailor music output to your hearing.[/COLOR]
