Can anyone identify this icon please

[Steve Hick]

Could someone identify the icon to the left of the bluetooth icon please

[AndrewL]

@Steve Hick: It looks like a screen mirroring icon to me. Do you currently have the phone connected to a TV? 

[DecisiveGorilla]

It's a cast icon, IF you have connected to your TV that icon appears

Thanks for that AndrewL  How do I turn this off as I have no need of it.

Thanks

Steve
