Downloads Oxygen OS Open beta 21-12 brings new launcher and no July 2017 security update

As expected, OxygenOS Open Beta 21 comes to OnePlus 3 and Beta 12 comes to OnePlus 3T. However, it does not bring the most expected July 2017 security update. We have been expecting it because the alternative firmware for Hydrogen OS H2OS Beta 18 does brings the July update. It features all the changes listed in the update log below. There is no reason to be completely disappointed as this Oxygen OS Open Beta brings some new additions, bug fixes, and optimizations.

Although you may be disappointed with OnePlus not deploying the latest security patch, you you can now enjoy the latest stock apps. The updated apps include New OnePlus Launcher V2.1.5, Gallery V1.8.0, File Manager to V1.7.1. This is great in terms of the new user interface and a step towards making Oxygen OS more likable. Besides the new apps, you will also find an all new parallel apps feature. It will let you run a parallel version of the same app using a separate account supporting Facebook, Twitter, Whatsapp, and Instagram at the moment.
