So if you go to the speaker option on the home screen and set it to loud, do you get all the rings? I use the vibrate and quiet mode several times a week and have not had any issues, also I just upgraded to 4.1 OS. I have the 7250, and if I can help let me know, I have had mine for a year and am still learning new things everyday. Also I have a great IT guy that helps me out anytime. IM me if you need to. I can't remember if I have messaging information in my profile, but if I don't I'll update it.
