The source of the leak is unknown, although the leak has been written in Chinese. According to it, Xiaomi’s new smartphone will sport:

– QHD+ display
– Snapdragon 855 Plus CPU
– 12GB RAM
– 1TB (!) flash space, UFS 3.0
– 45W charge support
– 108 Mpix ISOCELL Bright HMX x 16 Mpix x 12 Mpix x ToF sensor main camera
– MIUI 11 OS

Other, older leaks also suggest that the device will come with the Adreno 640 GPU and will lack the microSD slot. Who cares, with 1 terabyte drive space… Xiaomi Mi Mix 4’s release date is still unknown.
