  1. My option for that is grayed out. How do I fix that?

    1. Hi Jason Sweitzer,
      Thanks for coming.
      Did you make any change before encountering this issue, e.g: change the settings, install third-party app, etc?
      However, a user in Androidcentral forum who has a similar issue with you confirmed that he could fix this issue by uninstalling update of the All Share Cast. So, try to give it a shot.
      If you don't know how to uninstall update, kindly using the following steps to do so:
      1. Go to Settings.
      2. Tap "More" tab.
      3. Tap "Application manager".
      4. Swipe the screen from the right to the left until you see the "ALL" screen.
      5. Scroll down to find "AllShare Cast Dongle S/W Update", and then tap it.
      6. Tap "Uninstall updates" button.
      7. Tap "OK" button to confirm.
      8. If needed, you can restart your phone.
      9. Once your phone is on, try opening Messaging app and then see whether the font size option is enabled.
