Previously people thought that Xiaomi will present their new phone from Mi Mix series 12th of September. However, there accidentally leaked official poster of Xiaomi which announces official presentation of Mi Mix 2, and there we can see another date - 11th of September, so phone will be announced a day earlier than it was expected.
Xiaomi Mi Mix 2 probably will have 6,4-inch AMOLED display with 2540x1440 resolution, Qualcomm Snapdragon 835 processor, 6 or 8GB of RAM, 128 or 256GB of internal storage without microSD slot and 5mpx front camera. In case of main camera many sources say about other configuration because some people say about 19mpx main camera, other pages write about 12mpx camera, and some people even say that Mi Mix 2 will have dual camera on its back. For confirmed information we have to wait until 11th of September.
