I get the voicemail password prompt every time I unlock the phone. This has been happening for about two weeks now. I think that that is also the time that I updated to 4.2. What is causing this and how can I make the prompt stop appearing?
That just happened to me today, my work called my cell phone, and I did not know I had a voicemail on my phone since it did not say I had a new voicemail at all. I saw the phone was asking for VM password and I enter my voicemail password, and then my voicemail messages apperead. it is fine now.
