I have BB 8330 I put 8 gig card in it long ago and i have thousands of songs on it and a hand full of videos. I convert my videos to a 3gp format. All seams to work well but one of them. It is about 30 min long. Sometimes it will play with no issues at all but MOST of the time when it starts to play it will come on and say loading then the whole phone will reboot by itself. So I removed the file and made the file smaller and put it back in phone, same thing it locked up phone after a few sec and rebooted. ANY THOUGHTS ? FYI no I have never formatted the card as I have NO issue with anything else.
