Hydrogen OS as we know it is an alternative ROM developed for the Chinese variants of OnePlus devices. Today, a new H2OS OTA update is rolling out that brings several optimization and bug fixes on our way. The update comes to the H2OS Beta versions with Open Beta 13 for OnePlus 3T and Beta 19 for OnePlus 3. There is nothing special about this update but it does bring some stability and several optimizations to stock firmware.

You can find repairs with running and taking screenshots while running multiple apps. Fixed weather apps not updating. Optimized long screenshots. Updated the browser to solve the multi-screen interface splash screen problem. You can see the complete changelog listed below.

OnePlus 3 and 3T recently got updated to a new OnePlus Launcher 2.1.5 with the previous Beta update. The new launcher features several optimizations to the user interface. It also brought updates to applications like the File manager, Gallery app, etc.

Does this Open Beta come with August 2017 Security Patch?

Considering the previous builds, this is simply an optimization update. So no. Hydrogen OS Open Beta 13/19 does not come with August 2017 security patch level. However, it is based on the latest Android 7.1.1 Nougat which is also present in the stable H2OS 3.0.

The H2OS Beta 19 is equivalent to Oxygen OS Open Beta 22. So the next OOS update for the OnePlus  3(T) is imminent. It may show up as soon as tomorrow or the first day of next week.
