MIUI 9 was presented in July, on the same event with new Xiaomi's phone - Mi 5X. Now, after months of beta tests it looks that premiere of new MIUI's version is closer than we could even thought. How says Xiaomi, stable version of MIUI 9 will be released on 2rd of November, at least in India. There is a chance that OS in China will be released even earlier, because it's rumored that people from China may get MIUI 9 by the end of this month.
From the most important new features which will be added to MIUI 9 we should especially take a look on new smart assistant, image search option, multi-window mode and improved security.
