A new tactile experience with Mi MIX 3's patented Magnetic Slider

Mi MIX 3's patented slider incorporates carefully calibrated neodymium magnets. When the screen is slid down, the magnetic mechanism automatically activates and completes the opening with a highly-tested level of force and satisfying click. Xiaomi has dedicated substantial resources to the production process, ensuring slider life of 300,000 cycles in lab testing. The full screen slider will offer customization via OTA, so users can set it to perform functions such as answering calls or starting the camera.

Advanced Full Screen Display, gorgeous ceramic design

Thanks to the slider design, Mi MIX 3 is able to push display boundaries even further. Mi MIX 3 uses a 6.39-inch 2340 x 1080-pixel FHD+ Samsung AMOLED display with an aspect ratio of 19.5:9. Its bezels have been further reduced to achieve a high screen-to-body ratio. Mi MIX 3 continues the iconic MIX implementation of artfully executed ceramic design, with a new Sapphire Blue version inspired by Chinese ceramic crafts.

Mi MIX 3 sports a 12MP + 12MP rear dual camera that includes 4-axis OIS and 2x optical zoom-achieving a DxOMark photo score of 108, making it one of the world's best smartphone cameras. To further improve low-light performance, Xiaomi has introduced a steady handheld night photography mode. The rear dual camera can record video at up to 4K, and 960 fps for slow-motion. The 24MP + 2MP front camera module makes great use of the Sony IMX576 sensor to capture more detail than ever before. In low-light conditions, this sensor implements Super Pixel technology to greatly improve light capture and overall photo quality. The secondary 2MP dedicated DOF camera captures depth information, enabling advanced AI bokeh.

Dedicated AI button for Google Assistant, wireless charging
