There are also new battery life improvements, better auto-fill options and notification indicators on app icons.
OnePlus allows anyone to join its Open Beta Program and manually sideload the latest Oreo beta.
However, OnePlus 5 owners should be aware that since this is beta software, it may be unstable and likely contains a number of glitches, incompatibilities and bugs.
If you’re using the OnePlus 5 as your primary device, it’s probably best not to install this beta release.
Thankfully, the fact OnePlus is rolling out Android Oreo beta once again is a solid indication the fully-featured public launch isn’t too far away.
