I am new to Android and have had my LG Optimus V for a few weeks. It was working fine until today when I got a text with a different ringtone than what I had chosen and it had been ringing with ever since I got it. I went into settings to change it back and found that it would not allow me to change my call or notification ringtone. The menu that would normally pull up with all of my ringtones now has "Silent" as the only option. Did I accidentally delete all of my ringtones?
