The latest beta build of OxygenOS brings something OnePlus 5 and 5T users are going to appreciate: support for Google’s Project Treble. If you aren’t familiar with this, Project Treble separates Android’s framework with the vendor’s hardware code implementations. This means handset makers are only going to be in charge of the parts they change in the software, while Google and the companies who provide the processors will be releasing updates on their own. This initiative hopes to help reduce fragmentation in Android. Unfortunately, this isn’t widely adopted yet.
But now for those OnePlus 5 and 5T users, your handsets will soon be compliant with the program. You would, however, need to flash these OxygenOS beta build if you aren’t running the previous version of open beta. And if things work out smoothly, then these phones should get the update in the coming weeks. On top of this, the new update brings with it a new user interface, support for accent colors, and changes to the launcher, phone, and weather apps.
