This morning I received the notification for a new update, after a long time installing, my phone greeted me with a "Welcome to Denim" notification and effectively, under Extras+information it said Denim. I rebooted my phone and now it shows Cyan again :( anyone with a similar issue?

P.S. Lumia 720 user (And I can still create folders by drag&drop, which I believe wasn't available on Cyan)

Are you using Preview for Developers? When I'm enable it, it shows Black but when I toggle it off it shows Denim.

I had the app installed but not activated, yesterday I did a firmware flash so I'd get Denim since in my country we're still waiting for Cyan so my phone was a clean install

Also happen to me. As a matter of fact, when I check Denim availability for my 520 in Indonesia, Microsoft website said it is available (with specific OS and firmware versions). When I check that info on settings->about, it shows exactly the same version. But Extra+Info still said I'm on Cyan.

As xrs22 said, when I turn off the Preview for Developer participation, Extra+Info is indeed showing Denim.

In effect, I activated and deactivated Preview for Developers and it now shows Denim... Weird behavior. Thanks guys!
