FontFix is a utility application for Android devices that allows users to change the system fonts. It supports FlipFont for all Android versions, including 6.0, and root access is not required for supported devices. FontFix provides over 4,300 fonts for Android devices. Users can install fonts downloaded from the web and access additional font settings on their devices.

One of the best features of FontFix is that it previews every font before installation, enabling users to see how it looks before applying it to their system. All fonts are free for personal use, and the majority of fonts are free for commercial use as well. However, Samsung devices operating on Marshmallowand later do not support installing free fonts from FontFix.

Overall, FontFix is an excellent application for Android users who want to customize their device's look and feel. It is easy to use and provides a wide variety of font options for users to choose from.
