Prevent Volume Buttons from Changing the Ringer & Alert Levels on iPhone
If you’ve ever let a child play with your iPhone, you know that every physical button probably gets pressed a few million times, often repeatedly. There’s obviously little harm in that by itself, but a fairly common scenario is that a parent hands their iPhone to their kid to play a game or watch a video, and then gets the iPhone back to put back in their pocket not thinking much of it. Then a few hours (or days) pass, and uh oh, the parent discovers they have been missing out on phone calls, text messages, alerts, and email chimes, because the phone isn’t putting out any sound at all, despite the mute switch not being activated.
