Latest OxygenOS Open Beta update for OnePlus 3 and 3T brings in ‘parallel apps’ feature with updated launcher

OnePlus has been regularly rolling out Open Beta updates for its 2016 flagships – OnePlus 3 and 3T. These updates bring along new features with them along with bug fixes and optimizations. After rolling out OxygenOS Open Beta update 20 and 11 for OnePlus 3 and 3T around two weeks ago, the company has now started rolling out Open Beta updates 21 and 12 for 3 and 3T respectively.


Like previous Open Beta updates, the Open Beta updates 21 and 12 also come along with optimizations and bug fixes, however, they also bring along a cool feature called Parallel Apps. With this feature, users will be able to use multiple accounts of the same app on their OnePlus 3/3T. For now, only apps like Facebook, WhatsApp, Instagram and Twitter are supported, however, we are expecting OnePlus to extend support for more apps soon.
