Summary:
I fixed the strange dialer on the phone, here's a picture:

{F6433134}

Now I have a few questions:

1. To get the '#', '*', & '+' symbols to show up I need to install a font that supports those glyphs. I've only found the font `fonts-mplus`. I can slice this font to only get those glyphs and package them here, or add this font as a dependency.

We should likely have a font like this installed anyway, so people can see weird glyphs on the internet.

2. Is the correct way to set font sizes `pixelSize: units.gridUnit`?

Test Plan: manual testing?
