Spoke to Samsung. Their customer service is second to none. Put the phone into safe mode, changed a few settings and its a new phone entirely. When it came it had no ring tones so i added one. Last week it turned into a beep and all my calls went to voice mail. After i was in safe mode, i had about 30 ring tones to select from, and found a setting that allowed me to receive calls again. Hard to work outchowxto get out of safe mode but somehow i did it and its all working again. Ill give it a month and if its still working may change my opinion of the phone.
