When I set my phone to vibrate I’d like to be able to set an expiration time for that. Say, for two and a half hours, if I’m at the movies. After that period has passed, the phone sets itself back to what it was before. Then I don’t have to remember to set it back to ring, and I don’t miss a bunch of calls the next day.
For all I know, there are phones out there that do this, but I’d like to have one.
