On my Droid 2 Global I was able to easily put it on silent mode from the home screen, and then follow the same steps to "unsilence" it.
On my Droid DNA (HTC) I can't figure out how to do that. I can get Power Off and Airplane Mode and Restart. But I can't figure out how to silence it before it should happen to ring, and then easily "unsilence" it when done.
Thank you for any help anyone can give!
