How do I get rid of the cast iron on top of my screen neat the 4g LTe icon.

Hello I'm wondering is there a way to get rid of the cast icon bc I never seen this before until this week. I'm not casting anything at all. It's just annoying to see it on top of my status bar. It's not on my notification tho. I have Samsung s8 hope I get some help

Screenshot? Like the Chromecast "cast" icon?
