Ever since my Droid RAZR M updated a few days ago apparently it has been sending the same text message to people twice. I had no idea it was doing this until I had one person I was texting tell me, then another one later. And it has been doing it constantly. I even tried turning my phone off then turning it back on. What can I do for it to stop sending double messages? Because I can imagine it is quite annoying for the person I text.
