Technical characteristics and key features
When it was released, the Xiaomi Mi 9T Pro had specifications that put it on a par with flagships costing twice as much, and the heart of the device was the Snapdragon 855 chipset, made with a 7nm process, which ensured high energy efficiency and performance in heavy games.
The retractable selfie camera mechanism deserves special attention, and engineers managed to realize a full-scale screen without cutouts by hiding a 20-megapixel camera inside the case, and the mechanism passed 300,000 retractable cycles, ensuring the design would last.
The display received a Super AMOLED matrix from Samsung with a diagonal of 6.39 inches. Support for HDR10 technology and the coverage of the DCI-P3 color space made the picture rich and contrasting. The fingerprint scanner built right into the screen worked fast enough for the technology of the time.
