Smartphone Xiaomi Mi 9, released in early 2019, has become a real benchmark for what should look like a modern flagship. the device met users with a revolutionary design for its time, which still arouses interest among connoisseurs of classic ergonomics. The front panel is devoid of any cutouts or bangs, which provides an incredible immersion in content.
The look of the gadget is largely determined by the use of premium materials that feel good in the hand, the main focus is on the curved glass Gorilla Glass 6, which smoothly transitions into a metal frame, which creates the effect of a "floating" screen and makes the edges almost imperceptible when tactile contact.
However, to fully appreciate what the Xiaomi Mi 9 looks like, you need to consider not only the front, but also the back panel, where the main visual features hide, and this is where the unique gradients, complex camera system and specific elements that distinguish this model from its predecessors lie.
Ergonomics and body dimensions
The size of the smartphone is dictated by the need to place a 6.39-inch display in the most compact case. Engineers managed to keep a width of only 74.6 mm, which makes one-handed control quite comfortable, despite the screen diagonal. The thickness of the device is 7.61 mm, which is an excellent indicator for a device with wireless charging.
The gadget weighs 173 grams. By comparison, modern flagships often pass 200 grams, so the Mi 9 feels surprisingly light in the hand.This is achieved due to the thin aluminum bezels and lack of massive camera modules that have become the norm in later generations.
The back panel is particularly rounded, and it has a very strong bend on the sides, so that the phone doesn't stick out of the palm of your hand, and ergonomics is the cornerstone, and the fingers naturally fall on the edge, without the pressure of the sharp edges.
💡
The compactness of the Mi 9 is achieved due to the thin screen bezels and the lack of massive elements on the back, which is rare for flagships in 2026.
Materials and build quality
The body of the smartphone is a sandwich: two sheets of tempered glass with a metal frame in the middle, a classic solution that provides high strength and pleasant heat transfer. The metal frame has a matte coating, which is almost fingerprintless, unlike glossy counterparts.
The glass on the back has a complex structure, in some versions it mimics the texture of the fabric or shimmers with all the colors of the rainbow at an angle. The Mi 9's unique feature is that there are no visible antenna inserts on the ends, because engineers used laser spraying technology to hide the lines under the glass.
⚠️ Warning: Slippery glass covering of the back panel requires the mandatory use of a protective case.Without it, the phone can easily slip out of your hands even with minimal tilt.
The build quality is highly evaluated by experts: there are no lufts between the frame and the glass, the buttons do not stagger and have a clear, short stroke, the assembly is monolithic, as evidenced by the absence of creaks when squeezing the body in the hands.
Face panel and display
The front of the device is occupied almost entirely by the screen. AMOLED-Samsung’s matrices, black here is really black, not dark gray, as on the IPS-The top and bottom are symmetrical and minimal, creating a limitless image.
At the top of the screen, in a narrow frame, there's a conversational speaker and an approximation sensor, and it's embedded in the top left corner, and it's a solution that allows you to keep the symmetry and not sacrifice the usable area of the display, as competitors did with the cut-outs.
The glass display is protected by the latest generation of Gorilla Glass 6. It is resistant to scratches from keys and small things in your pocket, however, like any glass, is afraid of falling on hard surfaces at an acute angle.
💡
To save the factory oleophobic film on the screen, use only soft microfiber fabric. Alcohol-containing solutions can accelerate the abrasion of the protective layer.
Back panel and camera module
The back of the smartphone is where the Xiaomi Mi 9 looks most recognizable. In the upper left corner is a vertical camera block that protrudes prominently above the body surface, which is an inevitable price to pay for using high-quality optics.
The camera module includes three lenses and a flash. On top is the main sensor, below is a telephoto lens with optical zoom, and below it is an ultra-wide-angle camera. The flash is located separately, just below the optics unit, which breaks symmetry, but is dictated by engineering solutions.
Under the camera block, in the center, is the MI brand logo. In the global version, it can also be marked "Xiaomi"; below, at the bottom end, you can see the inscription "Designed by Xiaomi" in small print.
Why is the camera bulging so hard?
Interestingly, the camera block is surrounded by a metal rim that protects the lens windows from direct impact when you put your smartphone on a table, a clever detail that is often missing from cheaper models.
Location of buttons and connectors
The ergonomics of the control arrangement are designed for right-handers, but they're also available for left-handers. There's an on button on the right end, just above the middle, and it has characteristic notches that allow you to feel it from the volume control.
Below the power button, on the same end, are the volume control keys, which have a small stroke and a clear tactile response, and on the left end there is a special tray that combines slots for two. SIM-map.
On the bottom end are the main communication ports, and this is the USB Type-C connector, the main microphone and speaker of the multimedia system, and it's remarkable that the 3.5mm headphone jack is missing, which was a controversial decision for 2019.
The top end is basically empty, and it's just the second microphone hole for noise reduction and the IR port, and the infrared port is a brand feature that allows you to use your smartphone as a universal remote control for home appliances.

Color solutions and versions
Xiaomi Mi 9’s color line is rich and deep, with the base and most popular color being “Midnight Black,” which features a deep black tint with a subtle shimmering in bright light.
The Ocean Blue variant is a gradient from dark blue to light blue, which is the most relaxed and strict color, perfectly combined with business style.
The most spectacular is Lavender Violet, where the gradient goes from purple to pink, creating a holographic effect, and there were exclusive versions, like the Transparent Edition, with a transparent back cover, through which you can see the internal components and the wireless coil.
| Colour | Type of coating | Visibility of prints | Features |
|---|---|---|---|
| Midnight Black | Glossy glass | Tall. | Classical strict look |
| Ocean Blue | Gradient glass | Medium | Smooth transition of blue tones |
| Lavender Violet | Holographic glass | Low. | It's shimmering pink and purple. |
| Transparent | Transparent glass | Absent. | You can see the inside stuffing. |
The color choice affects not only aesthetics, but also practicality of use: black is clearly visible any dirt and dust, while gradient versions better mask the traces of exploitation in everyday life.
⚠️ Note: When buying a used device, carefully examine the frame around the camera block. This is where the most common chips of paint or scratches due to constant contact with surfaces.
Comparison with modern models
If you put the Xiaomi Mi 9 next to the current models from 2026-2026, the difference in the size of the camera modules is striking: modern giants occupy almost half the rear panel, while the Mi 9 looks miniature and neat.
Also worth noting is the lack of a protruding camera box across the width of the device, which is compact and vertical, which allows the smartphone to lie flat on the table without swinging unless you use a case.
The thickness of the bezels around the screen of the Mi 9 still looks decent, although modern bezel-less solutions have gone even further. However, the symmetry of the upper and lower bezels of the Mi 9 is better implemented than many budget modern counterparts, where the “chin” is much wider.
Is the Mi 9’s design relevant in 2026?
In conclusion, the Xiaomi Mi 9 remains one of the most beautiful smartphones in the company’s history, with its balanced proportions, quality materials and lack of compromise solutions like huge cutouts making it look timeless.
It looks light, airy and technological, and even years after it's released, it doesn't make you feel obsolete, unlike many models with bulky designs.
