My Samsung SCH-a310 has a feature which allows voice messages to be stored directly onto the phone rather than on a remote voice mailbox. I had a greeting for the phone after which people could leave a message if I didn't pick up the phone. I tried to change the message, but I messed up and when I tried again, all it recorded was one second of silence. I took it to a Verizon center and the guy there had no clue what was going on - his best guess was that it was a memory issue, which he then ruled out because only about a third of my total voice memory (dialing, memos, etc.) was used. So, any ideas?
