Can't be done
Perhaps it can be done for jailbroken iPhones?
It's strictly not allowed for official third-party iPhone apps.
You really don't have the energy to take your phone out and switch the vibrate off or on?
It probably isn't a matter of energy, it's probably a matter of remembering / finding time to do it.
Say you run into class, nearly late, stumble into your seat, the teacher is giving you an eye as he starts his lecture. Do you really want to fumble in your pocket and pull out a phone to switch it to vibrate?
He's probably giving you attitude because you're disrupting the class and why would you have to wait until after you've entered the class to put your phone on silent? Does anyone think about someone other than themselves these days? Apparently not.if a teacher gives me attitude for pulling my phone out to put it on silent I'll just acknowledge him and respond with something like "alright then, I'll just leave it off of vibrate."![]()
