Last rumours suggested that Xiaomi might announce three new devices today, but instead of three, the company unveiled two flagship smartphones, the Mi 5s and Mi 5s Plus. Both smartphones will be available in China, starting this week, on September 29.

The biggest differences are the dual rear camera and bigger display size on the Mi 5s Plus. The rest of the specs are almost identical. Both have metal unibody that is slightly thicker than the Mi 5, with an ultrasonic fingerprint sensor and MIUI 8 based on Android 6.0 Marshmallow.
