Brand new phone and the notification or call sounds do not work. Media speaker is fine. General speaker doesn't work. Anyone else have this problem?
Is your "do not disturb" setting on? What carrier are you using for your phone and is it on the latest software version? You can check the software version by going to (Settings > About Phone > Software Information > Build Number (last 4 characters))
Are you able to play any music on the phone through your speakers? If yes then there might be some settings you have done that ringtone did not work.
You may have to service your phone to the repair center. Samsung is offering discounted repair for front liners in the USA go check them out.
