OxygenOS Open Beta 13/11 Update – Changes and New Features

Despite the presence of the company’s latest flagship – OnePlus 6, the developers are paying a lot of attention to the devices released during the last year. Both the OnePlus 5 and 5T have been receiving constant software updates via Stable and Open Beta channels. This month, OnePlus has decided to surprise the users with a rather major feature inclusion. So before we head on to the instructions to install OxygenOS Open Beta 13/11 on OnePlus 5/5T, let us take a look at this specific new feature and the rest of the changes.

The announcement was first made at the official OnePlus community by staff member Manu J. The official changelog as stated on the release thread is as follows:

  • A brand new user interface
  • Support for accent color customization. To do so, go to Settings -> Display -> Customization
  • Supported Project Treble
  • Improved search tags in the app drawer
  • Added “New installs” category tag in the app drawer
  • Improved app list for hidden space and toolbox
  • Optimized logic for the contacts page in the Phone app
  • Redesign UI for improved user experience

As you can see, there are two major inclusions in this very update. First and foremost is the support for Project Treble. The developers have most likely utilized the unused space to create a separate vendor partition. This means a great benefit for an end user, both officially (Faster software updates) and unofficially (Faster ports of upcoming Android versions, Generic System Images of famous custom ROMs, and more).
