In addition to the beta update, the May Android Security update is also being rolled out.
The open betas also bring some other new features. This update finally adds Group MMS feature inside the "Message" app. The upcoming OnePlus 6 is will be powered by the latest Qualcomm Snapdragon 845 processor and will come with a notch screen just like the iPhone X. The OnePlus 6 will cost more than the current OnePlus 5T, which was recently updated to Android 8.1 Oreo operating system. A new Toolbox card is available in the OnePlus Shelf, and there's a new Hidden Space in the app drawer. Switch makes it easy to transfer your data from your current device to your new OnePlus device. The OnePlus Switch is also getting general bug fixes and stability improvements. It brings a completely redesigned user-interface for backup & restore and an optimized logic for the time remaining. However, those who own the OnePlus 5 and 5T will probably have to wait until later this year for the Android P update since the final version of the OS hasn't been released yet. It is not clear what OnePlus means by the Hidden Space in the app drawer, but it notes that the update also brings support for editing dynamic icons like the weather, clock and calendar.
In terms of software update, the OnePlus 3 is getting Open Beta 36 while OnePlus 3T is getting Open Beta 27.
