This problem has happened a few times now on my Droid 2, but not sure if I can replicate the issue on demand for technician. Basically, when listening to music on the music player and operating another app (such as reading FB status updates on Moto's Social Networking app), after 20mins the phone would freeze then automatically reboot. I think this also happened when listening to music and playing a blackjack app. I'm assuming this is more of a media player issue as I have had issues with the player in the past (ie does not support media file even after i played it before). However, I hope it's not because the phone cannot operate 2 apps simultaneously. Has anyone had this problem and any ideas to resolve? Any feedback is appreciated.
