Xiaomi Mi Mix 4 Presented: Camera under display and new top CPU

With the Mi Mix 4, Chinese manufacturer Xiaomi has introduced its latest flagship smartphone, which for the first time uses a front camera in its own product range.

The Xiaomi Mi Mix 4 is basically a luxury smartphone with a sophisticated high-end technology, but it stands out because of the way the camera is integrated on the front. It does not sit in a “notch” or rounded “punch hole”, but directly below the display surface at a certain point.

Lots of effort to cover the front camera

The front camera area uses a specially designed AMOLED panel with a unique pixel layout. Xiaomi talks about arranging the display pixels of the OLED panel in a “micro-diamond” format in front of the camera. The interior of the display has also been redesigned to allow more light to fall through the surface of the camera so that it does not scatter over it.

With its adjustment, Xiaomi claims that the display quality on the front camera front is not affected. A pixel density of 400 pixels per inch should be achieved there, which still corresponds to a very high level, as usual with current displays of a similar design. The camera uses a 20-megapixel sensor, which uses software to do pixel pinning to deliver 4-megapixel photos.

By combining multiple sensor pixels, the camera can ultimately deliver better images because it enhances the clarity and richness of the detail. So you still struggle with the fact that the camera still has a certain blur at full resolution because it has to take photos through the scene.

The new Qualcomm Snapdragon 888 Plus under the hood

Technically, the Mi Mix 4 is more than impressive. The 6.67-inch AMOLED panel works with 2400 x 1080 pixels and offers a maximum 120 Hz refresh rate. Dolby Vision and HDR10 + 10-bit color reproduction are supported. On screen is the Gorilla Glass Victus, the seventh generation of Corning’s hard mirror.

The new Qualcomm Snapdragon 888+, a slightly faster version of the current high-end SoC from the US manufacturer, works under the hood. Depending on the model, eight or twelve gigabytes of LPDTR 5 RAM and 128, 256 or 512 GB UFS 3.1 storage are provided. Xiaomi is said to pump the battery of the new Mi Mix 4 with its 4500 mAh up to 120 watts in 15 minutes. Alternatively, you can charge up to 50 watts wirelessly.

The cameras on the Xiaomi Mi Mix 4 should also be convincing: the Samsung HMX camera sensor focuses on 108 megapixels, f / 1.95 aperture and optical image stabilizer on the hardware. In addition, there is an ultra-wide-angle camera called a “freeform” lens, which makes regular distortions obsolete through a special shape. This camera works with a 13 megapixel sensor, 120 degree wide view and f / 2.2 aperture. It also has an 8-megapixel camera with periscope optics, which offers five times the optical zoom and a hardware image stabilizer.

Xiaomi wants to score with “Uniform” design ceramic housing with Mi Mix 4. The housing is said to be made in one piece and there are no changes or attachments that need to be glued or screwed on. However, it remains to be seen how strong the device will be in the end. Stereo speakers from Hermann-Garden are also part of the equipment.

The Xiaomi Mi Mix 4 is expected to go on sale in China this month, ahead of its international release. The base version costs 5000 yuan, which is equivalent to 660 euros.
