I love the speaker phone function in cell phones. It's a little quiet on the Maxx though. Playing with it yesterday I noticed that the speaker is on the top not the bottom like all my other phones.
So when on a call I held the phone upside down and my hand acted like a resonance chamber and it was clear as a bell.
I tried gripping higher up on the phone but it didn't feel secure. You don't need to see the display do what the heck? Works for music too,
