SamFonts is an Android app for Samsung devices that lets you install custom fonts on your phone without requiring root access. You pick a font file from your storage, the app packages it into a format that Samsung's system understands, and installs it so it appears in your phone's standard font settings just like a font that came pre-loaded. The app works by building a real Android app package on the fly, entirely on your device, using your chosen font file as its contents. It handles all the low-level technical requirements: rewriting the package's internal metadata, adjusting byte alignment so the package meets Android 11 and newer requirements, and generating a unique cryptographic signature in memory so the package can be installed. None of this requires sending anything to a server or installing anything from outside official channels. The installation itself uses a tool called Shizuku, which grants apps elevated system-level access without full root, and communicates with the package installer through a privileged process pipe rather than writing temporary files to your storage. The user interface is designed to match Samsung's own OneUI 8.5 visual style, built with Jetpack Compose (Android's modern interface toolkit). It has three tabs: one showing fonts you have already installed, one showing fonts available from your storage, and one about page. Each font entry shows a preview rendered in the actual typeface. The app automatically labels fonts as coming from the system, from Samsung's built-in packages, or from SamFonts itself, and pins your currently active font at the top of the list. Requirements are a Samsung Galaxy device running One UI 8.0 or higher (Android 14, API level 34), with Shizuku installed and authorized. The app supports both regular and bold variant files per font. It is released under the Apache 2.0 open-source license.
