yesterday and today I was getting notification sounds. I have separate notification sounds for my daughters and I kept on hearing my daughter's "sound" yesterday but there was no text from her. Again today! And just now my other daughter's notification sound is coming back again and again, and....when I tried to text, (using swift key X) now it only types in numbers and symbols? WHAT HAPPENED? I am now doing Swype cause I don't know what else to do. HELP
