OnePlus has announced the Android 8.1 Oreo support via the OxygenOS Open Beta 6 for OnePlus 5 users with additional new features and bug fixes. Both of these packages will bring the phone to Android Oreo, along with updating the Android security patch to February 2018.
Of course, the biggest change with this beta is the fact that you're getting updated to Android 8.1 Oreo, but there are also some other changes afoot here.
Compared to its predecessor OnePlus 5, the secondary telephoto lens on the 5T has now been replaced by a 20-megapixel sensor with f/1.7 aperture for better low-light photography and improved depth-of-field. It also comes packed with general bug fixes and improvements. Users should note that this Android 8.1 Oreo update is for those who on the beta version of OxygenOS, and those on the stable build will not see the new update. As a part of the gaming mode, the smartphone gets new optimizations for immersive gaming experience and these optimizations include pausing adaptive brightness, power saving, and notifications blocking. It also comes with OnePlus Switch feature to allow users to migrate application data, which will ensure customers can seamlessly switch between device. If you are already running the beta software from OnePlus, this update will come through as an OTA, so there's no need to sideload this update. The update weighs at about 1.6GB and the first time Beta testers have to manually download and flash the update. Users can also report bugs they find using the bug report forums by posting on the OnePlus forums. It can be downloaded from the OnePlus website. However, advanced users can get a taste of upcoming features and software through the open beta program, before these features are thoroughly tested and rolled out as stable OTAs. According to the changelog provided by OnePlus, there are some changes with the Phone app. This means, OnePlus 5T users will be able to answer an incoming call just by picking up the device in hand. The company is known for taking user feedback strongly, and issues many of its updates and software-based features based on requests by users.
