I noticed my charging light flashing blue (not charging or plugged in to anything). This usually only happens if I have a notification of some type, but this time I can not find anything going on. I don't have anything in the notification area. I have no voicemails. I have turned off the Titanium Backup notification. Yet, the light continues to flash blue. I'm at a loss as to what the phone is trying to tell me. Any suggestions? Thanks.
