Nokia 8.1 got a new update. I know that many hoped for Android 11 since the device is popping up on Geekbench with it, but it is just a security patch. Nokia Mobile released 32.41 MBs of patches which should make your device safe till the new one arrives.
The update should be available globally, so if you are owning Nokia 8.1, do check if the update is showing up on your device. The list of updated Nokia devices for March on our Update tracker page is a bit skinny, but I have a feeling that updates will start pouring soon.
