It might seem unusual for OnePlus to have some sort of delay when it comes to updates, but it does happen. The company started rolling out the OxygenOS 10.0.5 update for the OnePlus 7T. The update brings a slightly out-of-date October patch, a fix for the double-tap gesture issue that lets you activate your display even when it's locked, as well as the usual system stability and bug fixes. The update is rolling out globally right now, so keep your eyes peeled for it to head your way.
