OnePlus is getting closer to releasing OxygenOS 3.0, based on Android 6.0.1 Marshmallow, and now it's made a preview build available for members of its community. Owners of the OnePlus 2 can now download and flash the community release if they wish to do so, and OnePlus is asking those that do to help it test certain aspects of the software, including networking, camera improvements, performance, and battery life.

According to OnePlus, this is what you can expect from this build of OxygenOS 3.0:

  • Android 6.0.1 Marshmallow upgrade
  • New OnePlus Camera UI
  • UI has been cleaned up: swiping up/down now switches between photo/video, whereas HD/HDR and flash settings live in the top right corner
  • You can now change the aspect ratio and toggle grid view without going all the way to the settings
  • New wallpaper picker
  • Easily preview and set both home screen and lock screen wallpaper in one place.
  • Shelf UX has been improved
  • No more edit mode, long press boards to rearrange or remove
  • General system performance improvements
  • Benchmarked 47% faster than OxygenOS 2.2.1 on key test scenarios
  • Fingerprint performance improvement
  • Tested 45% faster than OxygenOS 2.2.1 on average
  • Settings changes
  • Old app permissions are gone, say hi to new (native Android) app permissions.
  • Alert Slider has its own entry point with more customization options
  • Improved settings menu readability by changing the order a bit
  • March security patches

For those that choose to flash this new build, there are some issues to note. Fingerprint data will be erased with the installation, so you'll need to register your fingerprints again. There have also been some Wi-Fi speed issues reported by soak testers.

Once you flash this build, you will be able to receive over-the-air updates, so you'll get all future releases of OxygenOS 3.0.
