[Representational Image] OmniROM brings Android Oreo 8.1 to OnePlus 5T via custom ROM: Here’s how to install In Picture: OnePlus 5TIBTimes, India/Sami Khan

It's been just a week since OnePlus kicked off the Android Oreo beta testing for the OnePlus 5T and going by the recent incidents, the company will take little more than a month to release the public version.

Earlier in the month, OnePlus halted the Android Oreo deployment for the generic OnePlus 5 owing to bugs, which affected the performance of the device. Just a few days back, it resumed the roll-out with glitch-free newer version.

For OnePlus 5T, the phone-maker, in a bid to avoid public backlash, is most likely to take more time to perform more stringent tests, so that there will no issues after the software gets rolled out to the device.

If you are not ready to wait for the official Android Oreo update, then custom ROMs are the only avenue to experience the Google's latest software first hand.

There are several custom ROMs in the Internet, among them OmniROM is one of the best out there. In addition to Google Android Oreo feature, it offers personalised options, themes, wallpapers and more.

What's coming in Android Oreo?

Android Oreo comes with several new features including Rescue Party feature, which helps device to recover from constant bootloops and also additional enhancement in security via Google Play Protect that checks suspicious activities and malwares in application, camera photo taking improvements, performance optimisation and latest security patch.

Android also brings new 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. And Smart Text Selection improves copy and paste. 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 also significantly reduces the booting time, extend battery life by cutting down on unnecessary activities of apps in the back ground, more fluid experiences to phones and tablets.
