While Nokia 5.3 is starting to receive a May security patch together with the Android 10 Maintenance update, the older Nokia devices are yet to get security patches. But, Nokia Mobile seems to be doing things at a quicker pace, so may security patches are coming to other devices, not just the newly announced ones. The users of the lovely Nokia 4.2 started receiving the May security patch which is only 7.26 MB large. The update is available here in Croatia, and most likely elsewhere in Europe.
If you are involuntarily holding your Nokia 4.2 in the hand, do check if the update is available, and share the location and basic info in the comments. We and all of the readers will appreciate that ;).
