Anki Small Questions Thread - (NO Technical / Troubleshooting Posts)

So, I usually use Anki for iOS, but since I got one of the super cheap Kindle Fire tablets for Christmas, I decided to try out Ankidroid on it after sideloading the Google Play Store.  For the life of me, I can't figure out how to make the text size any larger.  On the iOS version, it's a simple matter of pushing up a slider, but even after pushing up the card zoom option in the settings, nothing changes.  If it makes any difference, all my cards were created w/ Rikaisama's Anki option, but... 

I'm stumped.  Completely.  Hopelessly.  Stumped.

Any Ankidroid users here who might be able to help?
