Update 1 (10/02/2020 @ 08:26 AM ET): New OxygenOS builds are also rolling out for the OnePlus 7T and OnePlus 7T Pro. Scroll to the bottom for more information. The article as published on October 1, 2020, is preserved below.

OnePlus has a commendable track record of pushing Android security updates for its devices. The company usually ships the latest Android security patches from Google to its current-gen flagships within days of their release, with similar updates for older devices following shortly thereafter. However, since the company is currently pushing OxygenOS 11 Open Beta builds for the OnePlus 8 series, it's yet to ship the September security patches to the devices on the stable channel. Thankfully, that's not the case for other devices in the company's portfolio as they've now started receiving the September security patches with the latest OxygenOS stable update.

As with all OxygenOS stable releases from OnePlus, the latest updates for the OnePlus 7 series and the OnePlus Nord will be rolled out to users in a staged fashion. This means that the updates will first reach only a handful of users today. Once the company confirms that there are no major issues with the update, it should roll out to more users.
