I've had my galaxy note 2 for 5 months now and I'm fairly familiar with how it operates and i had everything how I liked it, then suddenly this afternoon I received a call from my friend and it didnt ring how it should have for him, after looking into this further all my contacts had the default ringtone set(which i had also changed, but that change stayed). I was worried so I went through and made sure nothing else was affected and most things were fine but the birthdays were all set to Jan 1, 1970. those few contacts with birth dates came from skype and there was a update recently but that was about a week ago...? I would like to recover these settings if at all possible without trying to go back and re enter everything so any thoughts or solutions are more then welcome.
