I downloaded the latest update for my Motorola Droid Razr M. I received a message that I needed to install the update, that it would take about 10 minutes to complete, and that I would not be able to use the phone during that time. I had a text message that I wanted to read first, so I clicked on that, and the install message disappeared. I can't find it on my phone. How can I access it so as to install the update?
