The users of Nokia 3 (2017) started reporting that the new Android 8.1 Build is available for their phone. The update V4.43E is 1883.5 MB large, and it brings numerous improvements across the system. The biggest changes are the new shutdown menu, new settings menu, battery percentage of connected BT devices, some stability improvements and the February security patch from Google.
Our Nokia 3 (2017) with the build number 00WW_4_42D_SP01 is still not getting the update, but hopefully, it will be available soon since it needs some tuning. Anyway, HMD said that this phone should be getting the Pie update at the beginning of Q2 so this could be an overture to it.
