Hi all I had this problem on my samsung s4. I figured out how to get rid of this annoying app watchon.
Go to settings, the select the more tab at the top the select application manager the select watchon. THEN SELECT uninstall updates when you Confirm it will ask you to set back to factory default select yes and this will get rid of it on all occasions and any previous settings will be erased for this app.
