I just noticed this yesterday, forgive me if this has been discussed but it's new to me and I figure I'd ask.
Whenever I'm on a call, I notice this new icon. It looks like this:

but it has white stars on the diagonal line.
It's on the top right of the screen, to the left of the volume...
What is it? I haven't made any upgrades in at least a month but I only noticed it yesterday, and I'm still running 4.3.
