Two weeks ago HMD Global announced the arrival of Android Oreo for Nokia 6 (2018) and promised an upgrade to the first-gen Nokia 6. The time has come and the original phone has started receiving the latest Android version.

The upgrade is 1659 MB in size. It brings refreshed Settings UI, enhanced power saving and background activity manager. HMD also tuned the low-light camera output.
The update is hitting both the Chinese TA-1000 and the Global TA-1003 versions, so start checking that notification area for the prompt.
Thanks for the tip, Sampath Bandara!
