Font previews

Preview the font before installing it to your system. You can also preview any font file you download from the web by selecting it from a third-party file manager or directly in the app.

FlipFont support

Samsung and other manufacturers support changing your system font without root access. All our fonts support FlipFont for all Android versions (including Android 6.0). Other font apps no longer work on Marshmallow.

Frequently Asked Questions

Is my device supported?

Supported device include:

A rooted device running Android 4.0+ with S-OFF (for HTC)
A Samsung device that supports FlipFont (root is not required)

After installing a font, nothing changed. Why?

If rooted, installing a font will overwrite files in the /system/fonts directory. Some applications load their own fonts at runtime. You should see your font applied in the majority of apps.

Support for applying fonts to individual apps will come in a future update for devices that have Xposed framework.

How can I avoid boot loops after installing a system font?

Installing a font on a rooted device can result in a boot loop. The app does everything possible to avoid this situation. Before installing a font to your system you should be familiar with ADB and restoring backups in your custom recovery. Always have a nandroid backup before making changes to your system.

If your device is in a boot loop you should reboot into recovery and restore your latest nandroid backup or a flashable ZIP to restore your system fonts. Wiping data will not fix the boot loop.

What is root?

The name root is the user name or account that by default has access to all commands and files on the Android operating system. Rooting an Android device is simply the process of gaining full, privileged, or admin control of a device, thus allowing ‘superuser’ permissions.

FontFix user reviews :

Absolutely LOVE! After I updated to marshmallow I wasn’t able to use any of my third party fonts I had previously downloaded. I ran across this app in a forum and decided to give it a try and I’m soooo happy I did. Love the app, I love that it’s user friendly and the variety of fonts available. Keep up the good work!

Nice looking app but needs an option to install all the font variants (light, bold, italic etc) in one go rather than individually, eg Open Sans has 10 variants and these need to be installed one by one
  • JRummy Apps Inc. May 7, 2016
  • You can change other variants. Long click on the font you want to change and select “Variants”. If the font has more than one variant it will show in a list. The app will auto-detect which system font file to install. You can also manually select which font file to overwrite.

Loved it! I really love this app.. but just a slight problem. The font englebert is way off screen.. could you fix this?
