I just got the HTC One today because the new Blackberry lacked a few options I needed for work, but I can't get the notifications to work in a way that makes sense. I can't seem to get the notification tone/sound to go off for text messages. When you go to "settings"....."sounds"....."notifications and alarms"... you choose your notification sound, but it doesn't let you assign it to a certain type of action. Help...
