After doing some research it looks like to me that there is no way to change font size in the app on Android. I like to create sub sections in my notes with larger font denoting the different section. Was trying to migrate over to Evernote from onenote and this would probably be a deal breaker for me unfortunately. I'm hoping I'm just oblivious and there is some way to adjust the font size on the Android app.
Thanks for the advice!
