The OnePlus 3 and 3T are now receiving the latest Open Beta software, which brings some updates and fixes to the two phones. The OnePlus 3 is receiving OxygenOS Open Beta 39, while the OnePlus 3T has OxygenOS Open Beta 30 rolling out. Users of either smartphone on the open beta software path will receive the new version as an OTA update, while users on the stable path will have to follow the steps (including a factory reset and sideload) to get onto the Open Beta program.
The new versions for the two phones bring a handful of new features and fixes, including improved search tags and a new installs cateogry in the app drawer, an improved app list for hidden space and toolbox, optimized switching between the front and rear cameras, and the added ability to scrub through AAC file timelines. Some of these features were also included in the Open Beta roll-out for the OnePlus 5 and 5T a few days ago.
There are both advantages and disadvantages to being on the Open Beta program. The pros are that Open Beta users continue to get additional software updates over a longer period, as well as experimental new features. However, open beta software is less stable than the regular software, and is therefore more susceptible to bugs and usage issues. On older devices such as the OnePlus 3 and OnePlus 3T, the number of versions and time that the program has been running means that the software will be relatively more stable.
