Hello

I have a weird icon showing up on the right top corner when making or receiving phone calls. The icon is rectangular in shape and has 5 small pluses in it..

I don't think I'm experiencing any problem making calls but this icon is bothering me. Can anybody tell me what this icon's supposed to represent?
Thanks a bunch in advance!

Perhaps the Enhanced Call Audio icon?

Thank you!
It turned out it was!

You can turn on or off the feature as it is mentioned in the other thread by going

Call Log > Options > General Options > Enhanced Call Audio

but I found out that you can also press 'L' during phone calls to turn this off.
