I downloaded the laurel wreath font and installed it into Phonto
When typing in the font, I only get letters, not the wreath. Am I missing something? How do I get the wreath to show up?

That didn't show me anything

Are you talking about that one http://www.dafont.com/laurus-nobilis.font ? It works fine with me.
Maybe Phonto doesn't load dingbats If you want to make sure, try with another one http://www.dafont.com/mtheme.php?id=7.

Still not working. Is there another font writing app I could use for Android?

Yeah, that's what I'm saying
