Hello! Here I have a zip file to share with you. It contains several font apps that contain many flip fonts all in single apps. There are over 400 flip fonts if you install all the apps. I got all these apps free from the play store. To be able to install all the fonts simply extract the zip file. There you will see several apps in the zip. Just install them as normal apps. Make sure unknown sources in settings is checked. Select your flip fonts from display in settings. All these fonts work with 4.4.2 kitkat on all galaxy s4 devices! I hope you enjoy!
