Can anyone tell me what this icon means?

I've had this icon on my phone for about a year now and no one has been able to identify it. Can anyone help me out?

Maybe the TTY symbol? What kind of phone is it?

its a razr maxx. What exactly is TTY?

It's for people with hearing disabilities I think.. Maybe you turned it on by accident. It's under settings/call I think

I googled RAZR maxx tty icon and found a older posts from DROID forums and someone had the same icon as you and it was tty..

Thank you!

No problem...
