In case you missed it yesterday, Nokia announced that their Lumia Black update was beginning to rollout. That update is a double punch firmware (Lumia Black) and OS refresh (Update 3). But there’s one question a few of you submitting to the site that has caught our attention: What do those little arrow mean for the system icons?
Many of you have figured it out, but for those who haven’t we have the details.

Full story from the WPCentral blog...

That will be useful to know when the wireless is being use.

I can't see those arrows!!! Does anybody know why?? Should I be concerned about this??

Nothing to be concerned about it just to show that it transmitting data through the WiFi.

And it only appears if you have updated your device to the Lumia black update.

Actually, I have Lumia black on my 1020... That's why I was wondering it... Thanks anyway, it's not seems to be a big deal...
