As we posted earlier, the next Oxygen OS update is here today after the H2OS Public Beta release. The Oxygen OS Open Beta 23 for OnePlus 3 will update your phone to latest August 2017 Security Patch from Google. The latest Open Beta program also features several bug fixes to the Phone app, Gallery app, Weather app, and the Clock app.  You will see a redesigned user interface which now supports battery percentage. Improved stability for Parallel apps can also be seen. There is a new feature called E-Warranty Card which displays the warranty in about phone option.

Same goes for the Oxygen OS Open Beta 14 for OnePlus 3. The camera app now adds Shot on OnePlus watermark where you can add your own custom name. See the full changelog from below.

Unfortunately, the update is not based on Android 8.0 Oreo. While OnePlus has promised Oreo upgrade for OnePlus 5 and the OnePlus 3 series phones, it may take a couple of months before its actual launch. Moreover, the Oreo update will be the last update OnePlus 3 will ever get. That said, OnePlus 5 Open Beta will immediately start once Beta program for OnePlus 3 ends with Oreo.
