Nokia 2.1, the needed update of Nokia 2, started receiving February security patch from Google. The update is available in India and has 32.34 MB of security patches. If you hanging out with your Nokia 2.1 now, do check if the update is there and make your device secure.
Strangely, while Nokia Mobile is updating older models, newer ones like Nokia 2.4 are still waiting for the update. The users of older Nokia devices should be happy of this, but in general, or ideally, all Nokia phones should be updated in the same month.
