OnePlus 3T Matte Black

OnePlus has started rolling out a new BETA branch update for its OnePlus 3/3T handsets; build version 21/12 respectively. The new update comes with a number of improvements /changes that may or may not make it to the stable OxygenOS build.

Following is the changelog from the OnePlus official forums,


OnePlus 3 and 3T Open Beta 21 and 12 Update

      1. Optimized home screen folder icon, with a preview look of first 4 icons in the folder
      2. Redesigned UI for folders, allowing switch between folders by swiping left or right
      3. Added double finger slide support, you can now slide the home screen with one finger while using another to hold an item
    2. Updated to Gallery V1.8

Although not an exhaustive list of changes, it is appreciated that the company has been so active with support for its older devices even after the launch of the OnePlus 5.

If you wish to test out these changes, you need to sign up and register for the OnePlus Open BETA initiative, here. Please note that this will cut you off from the regular OxygenOS build and if you wish to revert to the latter you would need to wipe your device clean.
