OxygenOS Open Beta 19 firmware can be downloaded for OnePlus 3/3T. This beta update is definitely a worth try as it brings heck lots of new additions & features. I will be mentioning the OxygenOS Open Beta 19 OnePlus 3 release note from the OnePlus official thread.

If you have already flashed any (newer) OxygenOS Open Beta firmware on OnePlus 3/3T, you’d be getting this update without any further ado. But keep in mind that once you flash this Open Beta firmware on OnePlus 3/3T, you will not be getting the official regular stable OTAs, that means, you may have to manually flash the newest stable firmware on the device. oneplus 3 oxygenos open beta 19

Last but not the least, moving back to the Official OTA path from the Beta path will require a full install and clean flash which might possibly erase everything on your device. So if you’re not sure about the consequences, you’re not supposed to try the Open Beta firmware on OnePlus 3/3T.
