The bezels around the display are very thin, making the screen appear even larger. The fingerprint scanner is located at the front, at the bottom of the screen.

The width of the device is 69.9 mm. After calculations and experiments, the manufacturer determined that this width is enough for the average user to use the phone with one hand.

If we compare the size of Xiaomi 12x with the popular Galaxy S22, then the hero of our review is 7 mm longer. But thanks to the optimal width, the model is compact and does not look bulky.

Smartphone Xiaomi 12x 8/125 (256) GB is a cool novelty. But what are the unflattering rumors we talked about at the very beginning? The fact is that bloggers received the first phones (Chinese version) for review back in January 2022. Some of them encountered an unpleasant phenomenon – in the cold, the camera began to “sweat”. Condensation began to accumulate between the lenses, photos and videos were cloudy.

When users got their hands on the Xiaomi 12x global (global version), the problem did not reoccur. Today, the camera of the Xiaomi smartphone 12x 256 GB is all right. We hope that no one else will have to face this shortcoming.

Now let’s talk more about the camera itself. The front one is quite suitable for clear and beautiful selfies, its resolution is 32 megapixels. The detail is high, the colors are natural. Various effects are available (for example, background blur). There is a night selfie mode, automatic beautification (narrowing of the face, enlargement of the eyes, smoothing the skin).

Rear cameras:

  • main 50 MP;
  • ultra wide-angle 13 MP;
  • 5 MP telemacro lens.

From the main camera, the smartphone can shoot video in 8K and 24 fps (frames per second refresh rate), and from the ultra-wide angle – 4K and 30 fps. There is optical stabilization – the video will not twitch. The Super Steady Mode option helps to achieve the perfect, shaky picture.

Various possibilities are available:

– shooting at long exposure with 6 types of effects;

– more than 10 filters;

– fast shooting mode;

– advanced night mode (noise reduction, sharpening);

– artificial intelligence – increases the intellectual capabilities of the camera and automatically improves the frame;

– recording immediately from the main and front cameras (for example, it is useful when recording the unpacking of goods);

– PRO mode – you can automatically adjust the exposure, focus, white balance, etc. This mode is needed if you want to experience all the capabilities of your smartphone to the maximum. Or, for example, you want to take an astrophoto. In night mode (even improved) it is not always possible to take the intended picture of the starry sky.

The Snapdragon 870 is on the model. Is this enough for comfortable use? Yes.

When testing AnTuTu (used to artificially test the performance of gadgets), the processor showed itself on a par with the Snapdragon 865 Plus. Such a processor is found in powerful devices, for example, in ASUS ZenFone 3.

How is such a test carried out? A special application is installed on the gadget and in a short time it loads the device to the maximum. Due to the large number of simultaneously running processes and tasks, you can see what load the gadget is ready for. As a result, the device receives a certain score.

What’s new:

  • Liquid Storage option – thanks to it, energy consumption is reduced by 10% (when compared with MIUI 12);
  • there is an always-on mode. An option that allows you to place some information on the screen in sleep mode.
