ironass, May 31, 2019 : See first post of this thread. WARNING! Open Beta releases are for competent and experienced users since they may not always be stable and are for the purposes of testing and reporting to OnePlus to help them develop future stock firmware and features. By installing this Open Beta, you accept the potential risks. Once on the Open Beta pathway you will no longer receive the regular OnePlus, Official Stable OTA's and you will need to wipe your phone, (data and cache), before attempting to return to Official Stable OnePlus stock firmware. See post #6 for how to do this. ironass motto... "Flash in haste... repent at leisure!"
