Why does my phone randomly play ads?

[Android Central Question]

I have a Samsung Galaxy S6 and my phone randomly plays advertisements. When I open RAM, it is some kind of app on my phone or something but I've never seen it before. When I open RAM the app or whatever it is says System Launcher or something along those lines. I've tried everything and nothing works. My phone also randomly stops recording video on my camera and randomly stops videos from playing. I've factory reset it already and it's still doing this. It still persists in safe mode.

Welcome to Android Central! Are they video ads or webpages in a browser popup? If it happens in Safe Mode, I'd be concerned about some kind of malware installed to the system root, which you can't get rid of unless you reinstall the firmware. To do that, you can use Smart Switch (http://www.sammobile.com/forum/showthread.php?t=29914) or Odin (http://forums.androidcentral.com/am...w-flash-stock-rom-via-odin-new-interface.html).
