Oneplus rolling out Open Beta software update – version 18 for the OnePlus 5 and version 16 for the OnePlus 5T. Changes in this version include a fix for beauty mode for the rear camera, improved stability for portrait mode on the front camera, improved stability for the weather app, and other general bug fixes and improvements.
If you’re already on the Open Beta software path, you’ll receive the software updates as OTA packages, but you also have the option to manually download and update the package from the OnePlus forum.
The changelog also mentions stability improvements to the Weather app along with some general bug fixes and improvements. The latest beta builds are less stable compared to official OTA and are likely to bring some additional bugs and issues, so it’s best to save your data before updating.
