Nokia Mobile updated the official update tracker located at nokia.com/phones/security-updates. The service provides a way for Nokia smartphone owner to check what update is last available for their device, but also see things like the end of software support for their devices and additional notes.
To check the info for your device, you have to know the SW ID located in the About screen of the device. After that, select your phone on Nokia Mobile’s webapp and find the ID. In this update, the newly announced Nokia G10, G20, X10, X20, C10, and C20 were not added to the update tracker, but considering most of them should go on sale next month at least in some markets, it is reasonable to expect them then.
