I'm trying to download and install the .apk file from Flip Font Collection that's free and gives over 300 fonts. I've done it w/no problem on the S3 for a few friends, so I got excited and wanted to do it for my S4, and although it installed the app, when I choose a new font, it says it's not available! Anyone else having an issue installing extra fonts? This is of course without rooting the phone. I just got it yesterday, I'm not ready to hack it and mess it up! Can you use ES File Explorer to copy them in manually?
