My Samsung Gusto 3 is less than a year old and just very recently will not play ringtones. My volume settings are fine. My keypad tones still sound. I tried checking for updates and even resetting to factory settings. It is very frustrating to not know when I am being called. The speakers shouldn't be the issue if the keypad tones and volume still work. I go into "Change ringtone" and the ringtones will not even Play there. How do I fix this because I constantly am missing calls! My kids worry me enough as it is!
