OnePlus 7 and 7T series OxygenOS update

OnePlus mentions that the new incremental update is rolling out in a staged manner. For the time being, the OTA is rolling out to limited number of users, wider rollout to follow in the coming days. If you’ve not received the OTA notification yet, then I suggest you to check system updates manually, by heading over to Settings > System > System Updates, in case it is not available then you need to wait for a few days.

OnePlus also allows users to sideload the update. It means if you want to update immediately if the new update doesn’t show up, you can use the OTA zip file. You can download the OTA files from the Oxygen Updater app. And after downloading, head to System Update and select local upgrade. Before upgrading, always make sure to take a full backup and charge your phone to at least 50%.
