You should note that the company has discontinued OnePlus 5 and hence the update will be available only for users who have access to the device. Additionally, the phone also gets a security patch update to April 2018.
OxygenOS 5.1.0 is rolling out to the OnePlus 5T and 5 now, and OnePlus says its broader rollout will begin "in a few days". However, this feature is only available for the OnePlus 5T. The highlight of the OxygenOS 5.1.0 update, of course, is navigation gestures, which will allow OnePlus 5T users to disable the navigation bar and perform swiping actions to navigate. The phones are now receiving OxygenOS 5.1.0, which apart from a handful of functional updates, also brings the two phones up to Android 8.1 Oreo.
Have you received Oreo 8.1 on your OnePlus 5 or 5T? The feature was first spotted in a beta release and it draws inspiration from the iPhone X. Swiping up from the bottom centre of the screen mimics the home button. A middle swipe will open the recently used apps in the multi-task menu. But, the timing of smartphone makers like Xiaomi and OnePlus introducing gestures for navigation to their devices can certainly be attributed to the iPhone X. However, gestures work differently for all the three smartphone makers.
Chinese smartphone brand OnePlus rolled out the Android 8.0 Oreo update for OnePlus 5 last year in December, and then in late January this year, the company rolled out the 8.0 Oreo update for OnePlus 5T as well. The update will also boost network while in gaming mode for a more seamless experience. Launch update brings category tags in the search section of the app drawer, and Auto name folders based on category. The update will rollout widely in a few days so do make sure to keep checking by heading to Settings System Update.
