My phone keeps have a "phantom" notification sound. It has been happening for about 24 hours now, it sounds a notification alert yet there isn't any popups nor is there a notification left on my notification bar at the top of the phone. Well after just kinda watching and waiting I've got narrowed down to Samsung sync, it sounds the notification alert everytime it syncs. I've had the phone for about a year and this has never happened before. I had no idea I couldn't disable that intrusive and private life shredding application!! Has anyone else delt with this problem and/or have a fix? Again that Samsung synce app is unable to be disabled and is as privacy shredding as Bixby.
