I have a phantom unread text that I can neither read nor delete. I have deleted all of my messages, but am still showing that I have one new message. When I view the "inbox" folder, it shows one message, but won't show when I enter the actual inbox. I can't figure out where to go in settings to get through a back door and delete the message. Please help.
This worked for me. Change your SMS settings. Go to Settings>more >default SMS and then switch to another messaging app(hangouts worked for me). Then if you want, change it back after your message comes through.
