Given it's gaming nature, you won't be expecting this phone to be as sleek or stylish as an Apple iPhone X or a Samsung Galaxy S9. Xiaomi Black Shark's main color theme is black with gamer green accents all over device. Phone looks rugged at first look and truth be told, it is a solid device.
At front, phone looks similar to OnePlus 5, however bezels on top and bottom of this device are smaller. There's a home button on bottom bezel which also acts as a fingerprint scanner. To right and left side of home button, you will find capacitive buttons for recent apps and return functions. These buttons don't light up when touched, and personally, I believe that is a great design decision by Xiaomi, given that it is a gaming phone. On top bezel, you'll find a front facing camera and rest of area is blacked out, giving this phone a stealthy look.
Back of this phone is made of plastic and there is a very prominent gaming theme going on. At top, you'll find a dual camera setup which is placed pretty much in middle. Both camera sensors and LED flash together with a mic are housed inside a black plastic panel which fits right into the body of phone. Panel is flushed as well, so you won't find any uncomfortable bulge and phone won't shake while sitting on a smooth surface. Going a little lower, there's a V shaped design which does creates a small bulge. You'll find Shark branding in middle of this phone, which is accented with gamer green color, giving it a very stealthy, gamer look. Below that is another V design bulge rotated upside down and all of this is enclosed within an area accented with gamer green color at border. When you look closely, you'll find a pattern of small triangles printed inside that enclosed area, which shows that Xiaomi put a lot of thought in giving this phone as much detail possible, something Razer Phone clearly lacked.
At right side of phone is where power button and volume keys are located. Finish on these buttons is metal so that gives a premium feel to device. On left, you'll find a sim tray slot and a 'Shark Space' button which activates gaming mode on this phone. Bottom of this phone is where you will find stereo speakers and USB Type-C port which is also accented with gamer green. Sadly, there is no 3.5 mm headphone jack or waterproofing to be found on this phone.
Quite frankly, this is first gaming smartphone which is built and made to look like a gaming device. It's solid, rugged and attention to details is just impressive.
