Red Mi Note, a phablet launched in March this year, seems even more potential than Red Mi, for it’s way more cheaper and considered better designed than all of precious Xiaomi models. But the company would continue to launch high-spec, higher-priced flagship models. It launches its fourth flagship Android phone today. The band is able to communicate with MIUI, the customized Android system powering all Xiaomi devices. So the band can, apart from tracking activities/sleep and working as an alarming device, unlock your Xiaomi phone.
