I have a voicemail notification when I drag down from the top. This notification does now show anywhere else, just when I drag down. The problem is this 'voicemail notification' will automatically dial a number when I touch it. I will not dial unknown numbers. I am unable to clear this notification since it does not show up under the phone app or visual voicemail app. Even if I tap on it and start to dial the number then end the call, it still is there. Any suggestions? I am on ATT with Galaxy S5, android v. 6.0.1.
