According to the earlier leaks, the Xiaomi Mi Mix 2 is expected to feature 93% Screen-to-body ration, which is almost bezel-less. With the Mi Mix 2, Xiaomi plans to compete the Galaxy S8 and the LG G6.
The 2017 Mi Mix is rumored to feature an Ultrasonic fingerprint sensor, which will be based on Qualcomm's latest technology which is capable of Scanning through Display, Thick Glass and Metal with Underwater Operation, Heartbeat and Blood Flow Detection.
That said, the Mi Mix 2 will be coming with Android 7.1.1 with MIUI 9 on the top. Xiaomi plans to release it later this year.
