Windows Central has reported that Lumia Denim is now starting to roll out in Europe on some Lumia devices, so for those of you who are eager to get this update, we suggest you manually check as you might just be able to download it before it gets automatically pushed to your device. Lumia 625 variants, 520’s, 530’s and Lumia 1320’s are reportedly starting to see this update.
These updates roll out gradually, so you may not see it right away, but be patient as the update is imminent.
Microsoft has a support page dedicated to Lumia updates where you can see the latest version of the software available for your phone in each European country.
