A new update has started rolling out for the Nokia 6. With a size of 149.3MB, the software upgrade should bump the version of HMD's mid-ranger to 00WW_3_72A.
Sadly, HMD's changelog for this update is rather laconic. It mentions that there are enhancements to the user interface and improvements to stability, but there are no precise details of what actually has been changed. Although not mentioned in the log, the update also brings the latest Android Security patch (November 6th, 2017).
The update is available OTA, but it might need some time to reach all compatible devices. You can check for it manually by going to Settings > Other > Software Update. As always, make sure that your phone is sufficiently charged and connected to a Wi-Fi network before proceeding with the patch.
