My ringer does not work when I receive messages, I can play the sound when I set it, but it doesnt work when i actually get a message
I am a volunteer firefighter, and our department is paged via text message. I have a certain tone set specifically for that message so I wake up when it goes off. I can play it when I set the sound, however when a message actually comes no sound is heard. I have missed two calls because of it and i am starting to get really frustrated. My volume is turned all the way up, but the only thing i get is vibration
