I open up "messages" then hit the "settings" option, then scroll down and "notifications" is checked and I then select my ringtone for whenever I receive a text message. However, upon receiving a text message, I hear the ringtone I selected, but immediately following the selected ringtone, I get another ringtone sound. It's like I have 2 ringtones set for incoming text messages. And the second ringtone is the "chirps" ringtone, which is e extremely annoying. So currently when I get a text message it plays the desired ringtone followed immediately by the chirping birds. Can someone pleAse help me fix this as it is driving me nuts!!!!
