When I tap the visual voicemail button, it simply calls my voicemail to retrieve the messages. How do I get visual voicemail? And I've also noticed that sometimes when I take a photo/video and delete it, it will show an odd black space where the photo used to be. I also synced some photos from my Mac and removed them, and the album was still present but blacked out where the photos originally were. Has anyone had this problem? Id also like to note that my phone was not restored from a backup.
