About Miui

---

MIUI which stands for Mi User interface & pronounced "Me You I" a play on the common abbreviation of the words user interface as UI, developed by Xiaomi Tech, is a stock & aftermarket firmware for smartphones & tablet computers based on the Google Android operating system.

What's new in Miui v8 Marshmallow?

---

The brand new Miui v8 comes with many new features:

• New redesigned colourful UI & fonts, and a new notification shade which comes with weather information,search bar & etc.
• New Miui 8 Gallery, Scanner,Camera, Calculator, Notes & Many more.
  The standard "Gallery" application has been changed in Miui v8. Xiaomi has been added more photo editings, such as inscriptions, stickers, & etc
• New Miui v8 lock screen wallpaper carousel
  In the orignal MIUI, there is such function as a carousel of images for the lockscreen. Its essence is simple the user sees a different wallpaper on lockscreen when it is activated In Miui 8 there is more than 100 wallpapers that u will find.
• Spam/Scam message detection
  Sometimes you might get annoyed with the unwanted scam calls & messages from your service providers & other sources. In the process of finding a way to get rid of it u might end up with downloading some bloat apps ( 3rd party apps ). This mainly happens because many users are unaware of the fact that Miui does have the inbuilt feature called Miui Blocklist to prevent these type of spam.
• System optimized for power saving & app management, so more power & smoother user experience
  In terms of performance, the user interface will be fast & reliable, power consumption optimised, very quick responsive, apps managing will become suitable & even more convenient. Extreme smoothness.
• Second Space
  We all know that we can make several user accounts in our desktop Similarly now u can make same thing in your android phone by using second space.
• Dual Apps
  Dual apps let you run two instance of an app simultaneously. One of the headlining feature additions in Miui 8 is Dual apps, Which allows you to run two instances of an app at the same time. This feature is good for those who has multiple social media accounts.
• And many more ;) ....

Since this was my first project in development towards opensource community this project has been taken so much time, continous testing everyday, & so much patience & when i finally managed it to boot the main part comes i.e Bug fixing part. And when Rom booted it has every thing broken like Ril, Dialer Fc , Settings Fc , too much lagging & many more . And i finally managed to fix them all :v
For this PatchRom i had taken LineageOs as base Rom Compiled My me with some Extra additions & Modifications like volte,doze, & Some kernel improvements.
