The latest OnePlus 7 and 7 Pro official betas have November 2019 security patches
OnePlus has announced a new official public beta build of its OxygenOS Android skin for 2 of its newest phones, the 7 and 7 Pro. It contains previews of fresh and updated features, including the latest Android security patch. This software channel, which is known as Open Beta as opposed to the conventional stable counterpart, also tests a new option in which the OEM's "screen-detox" app Zen Mode can be disabled.
This new Open Beta 6 update also fixes an issue by which the fingerprint scanner, which is set into the display, was not signified well enough in the UI. This display effect also has animations that indicate its activation, which are also apparently improved in this beta. It also contains general system and stability housekeeping.
Therefore, the latest Open Beta for the 7 series is slightly but significantly advanced compared to the stable version (OxygenOS 10.0.2, which is still on the October 2019 security patches). This doesn't make the general-consumption channel any less functional, of course.
However, those interested in switching from one to the other would be advised to follow the instructions on OnePlus' community website carefully while doing so: for example, 7 or 7 Pro owners still on Android Pie- (9.0) based software need to download and install Open Beta 5 before proceeding to its immediate update.
