Nubia’s smartphones have become known for their design language, something that isn’t changing with the Nubia Z9. We can say they took a conservative approach by adopting the same design formula we have seen a few times in the past. I personally believe this is not really a bad thing.

The Nubia Z9 adopts a rectangular slab shape. It’s made of high-end materials, sporting a metal frame sandwiched by a glass front and back. These characteristics, along with the chamfered edges, make for a smartphone that manages to feel great in the hand. It truly gives off the impression of being a very solid and high-quality handset. It also helps that its angular design and unique edges provide a good grip on the device. One would imagine a phone made predominantly of glass should be slippery, which is not really the case with the Nubia Z9.

A lot of manufacturers these days sacrifice specs and power for a svelte body. I believe I am not alone when I say that’s not the smartest choice, but the industry is all about it. Not Nubia, though! This smartphone is 9 mm thick, so it won’t be winning any thinness contests. It’s noticeable the manufacturer wasn’t focusing on this, as there is no taper on the back trying to simulate a thin profile, either. You will feel every single millimeter when you pick this phone up.

It doesn’t help that this is not the lightest phone, weighing in at 200 grams. The weight will definitely take some getting used to, especially if you come from one of those super thin smartphones, but it’s something you can definitely get over once you realize the benefits a thicker handset can offer; among them is a larger battery (more on that later). Not to mention, the thickness and weight gives the Nubia Z9 a solid feeling. You will be reminded this is a high-quality device every the moment you pull it out of your pocket.

In terms of ports, buttons and connectivity, the Nubia Z9 comes with a pretty standard set. You can find the 3.5 mm headset jack up top, as well as a microphone and IR blaster. On the right side there’s a metal power button, accompanied by the volume keys and a dedicated camera button (these all offer great feedback and a solid quality).

On the bottom we can find a lonely microUSB port and what may appear to be dual speakers. The key word in there is “appear”, as only one of them is a speaker – the other is a microphone. Finally, the left side of the phone houses nothing but a dual-SIM card slot.

The design team adds some contrast by including a red ring around the camera, as well as the home button in the front. There’s also a couple glowing red capacitive buttons right next to the home button (menu and back). By the way, you can easily switch around their order in the settings.

Display

I have to say the display is likely the main attraction in the Nubiz Z9. This screen is fantastic! It sports a 5.2-inch 1080p panel. It may not have that Quad HD we have gotten so used to by now, but we have often said a good display is not always the one with the most pixels.

A quality screen is graded by other factors. The Nubia Z9 makes up for the 1080p resolution by offering bright and vivid colors, as well as spectacular outdoor visibility and good viewing angles. Not to mention, its 400+ PPI pixel density makes for a more than fair reading and media experience.

Aside from offering a quality panel, Nubia managed to make the Z9’s screen stand out (literally) by adding a curve along the edges. They had to use 2.5D glass to achieve this, but it’s totally worth it. The screen has been raised above the frame, giving it a much more prominent curve and making it a pleasure to swipe across the screen. This design element gives the impression that one is simply holding a completely bezel-less phone, but you can certainly find the edges upon closer inspection.

It resembles the Samsung Galaxy S6 Edge in a certain way, but the curves on the Nubia Z9 are not drastic enough to alter your viewing experience. Nubia did add some nifty software tricks to take advantage of this peculiar display, but more on will be covered later in the review.
Performance

Performance will be slightly different depending on which version of the device the customer gets. You can opt for either the Classic, Elite or Exclusive editions. The main difference between these rests in the RAM, internal storage and the inclusion (or exclusion) of a fingerprint reader. All devices come with a Qualcomm Snapdragon 810 processor, but the Classic version (the one we have for review) sports 3 GB of RAM. The Elite and Exclusive editions tout a mighty 4 GB of RAM, while only the Exclusive edition features a fingerprint reader.

Regardless, we have had a great experience with the Nubia Z9 in terms of performance. Basic tasks like navigating through he UI and using apps are a breeze. We also found no issues trying to multi-task (of course, this thing has a massive amount of RAM memory) or playing graphically intensive games.

The Qualcomm Snapdragon 810 processor was off to a bad start, with plenty reports suggesting phones were getting exceedingly hot. Is the Nubia Z9 plagued by the same cumbersome heat? It sure does get warm, but we found it was never an extreme over-heating case. It was nothing to worry about.

In terms of the differences between 3 GB and 4 GB of RAM, we believe there won’t be a significant gap. Sure, in theory the 4 GB version will likely run a little better and feature superior multi-tasking, but 3 GB is plenty of memory for a smartphone. Differences will be small at best.
