Xiaomi took more than a year to develop Android Nougat MIUI 9 and it recently released it to the Redmi Note 4. As of now, there is no word on when the company will deliver the latest Android Oreo to the popular mid-range smartphone.

If patience is not your strongest suit then there are custom ROMs, which offer first-hand experience of the new Google software with value-added features. Coincidently, the good folks at popular custom ROM community, OmniROM, have released the latest Android Oreo 8.1 ROM for Redmi Note 4 devices.

What's new in Android Oreo?

Android Oreo comes with several value-added features such as picture-in-picture, which allows users to do two tasks simultaneously, like checking the calendar while planning a party on a Duo video call.

There's Smart Text Selection that improves copy and paste function.With the help of machine learning to recognise entities on the screen—like a complete address— users will be able to easily select text they want with a double tap, and even bring up an app like Maps to help during navigation.

It significantly reduces the booting time, extend battery life by cutting down on unnecessary activities of apps in the background, and offers more fluid experiences to phones and tablets.

Most notable aspect of the Android Oreo is the Rescue Party feature, which helps the device to recover from constant boot loops, and also offers additional enhancement in security via Google Play Protect that checks suspicious activities and malware in an application, camera photo taking improvements, performance optimisation and latest security patch.
