Xiaomi has announced the newest version of MIUI alongside the new Redmi Note 2. MIUI 7 is based on Android 5.1 Lollipop and comes with a bunch of new features. One of the features is face detection mode in the Gallery app, that can recognize faces and sort images according to the people in it in the People tab. The software is even able to identify and differentiate pets. MIUI 7 also has a handful of new themes, including a pink 'Goddess' theme targeted at women and as usual you can download more from the store. MIUI also has a new feature called Mi Roaming, which acts as a virtual SIM for when you go out of your country, allowing users to purchase data packages from Xiaomi and use them instead of getting a new SIM. This feature is only available in China for now. MIUI 7 can also let you set videos for contacts, which play when the person calls you. Lastly, there is also a Kids Mode, which restricts what content kids can access on the device. MIUI 7 will start rolling out for Mi 2, Mi 2S, Mi 2A, Mi 3, Mi 4, Mi Note, Redmi, and Redmi Note tomorrow in China. Xiaomi will be officially announcing MIUI 7 in India on August...
