Change Fonts on One UI 8: Step-by-Step Guide
One UI 8 broke custom fonts? Here’s the working, no-root fix using Shizuku + MT Manager—fast, safe, and Samsung-friendly (2025).
Tired of failed installs and broken methods after One UI 8? In this step-by-step guide I show you how to install custom fonts on Samsung without root using Shizuku and MT Manager. We’ll grab a free base font from the Galaxy Store, swap the .ttf inside the APK, sign it, and install—so your favorite fonts (like SF Pro) apply system-wide on One UI 8 devices (S24, Fold/Flip, Tab). I also cover common errors, why this beats ZFont, and how to keep Shizuku working with Wireless Debugging.
