Remote icon on Galaxy S6 Edge

Based from a thread on Android Central, it's an icon from Peel Smart Remote app.

uestraven recommended to disable the app to remove it.

[...]. I just figured it out. It's Peel Smart Remote app. You have to disable it.

It seems the icon was added on the latest update as IAmSixNine wrote,

I updated the Peel Smart Remote app on my GS6 and after I rebooted the phone, it showed up on mine as well. Pretty annoying if you ask me that they did that. I don't and have never used the app and for them to update the app and then force that on me is pretty lame.
