MIUI 9 is Xiaomi’s latest OS update based on the latest stable version of Android Nougat 7.0. Xiaomi has currently rolled out this update to a couple of its Redmi devices. While MIUI is not that great or optimized when compared to the stock version of Android, it still has its own set of disadvantages.

For instance, Xiaomi’s MIUI comes with built in themes which could be used to customize the entire device with different colors and icons. Stock Android does not support this as of now. MIUI also gets several other exciting features that are not available in stock Android like, dual apps, scrolling screenshots, and quick ball.

So, if you are a proud owner of OnePlus 3 or 3T and have a liking for MIUI 9, then you are in for a treat because you can install the MIUI 9 custom ROM right now on your device. However, you have to keep in mind that, this is only an Alpha build and it might have some problems here and there. But, the basic features like WiFi and calling works.

If you are still enthusiastic to try out the MIUI 9 ROM on your OnePlus 3 or OnePlus 3T, then follow the below guide to do so.
