TL;DR
- Samsung’s March 2026 security patch has broken custom fonts for some users.
- The broken custom fonts might be due to Samsung fixing a font-related flaw on its phones.
- Galaxy owners can still apparently download custom fonts via the Galaxy Store, though.
Like many Android OEMs, Samsung lets you switch to custom fonts on your phone. This is great if you’re not feeling the default font styles for some reason or if you simply want a fresh look. Unfortunately, it sounds like a recent update is breaking this functionality.
Samsung owners on Reddit (1, 2) have reported that they effectively lost custom fonts after updating to the March 2026 security patch. The issue seems to affect users on both One UI 8.5 and One UI 8.
