Where is the noisy button? Seriously, my received calls are important.

Can we please have a single button (or focus mode) to return the phone to loud? There are so many ways to silence the phone it's easy to have it accidentally silent. Aside from calling yourself from a different phone, it's difficult to be sure it's going to ring.

For those of us who do business on the phone, it's important to hear it ringing. A silent "Work" mode makes no sense, if work involves taking phone calls.
