Really, it's just Google Voice that's having the problem... I Have 4.8 with Google Voice installed on 4 phones in my office including mine, but I'm the only one having this problem. Yesterday I got a voicemail icon that said I had a new voicemail... I never missed a call, but I checked it anyway... I didn't have any new voicemail; I also deleted all of my stored messages, as well as rebooting my phone several times. Also deleted the app once then rebooted and it was still there... any ideas?
