• 🌐 On the official website of Samsung Design (section "Resources") - there are.ttf and.otf files for personal use.
• 📱 Through the Galaxy Store app (if you have a Samsung device) – there are free font packages in the Themes section.
• 🔍 Google Fonts (search for “SamsungOne”) – sometimes unofficial ported versions appear here.

For Xiaomi. MIUI The situation is more complicated: the company does not distribute the font MiSans (mainly in the MIUI 12-14) separate from the firmware. However, there are verified sources:

• 📦 Font archive MIUI on the forum Xiaomi.EU (look for topics marked with a note "[Font]").
• 🛠️ GitHub repositories (such as miui-devs) where enthusiasts upload files pulled from firmware.
• 📱 Built-in Themes app on Xiaomi (Section "Fonts") - there are both standard and custom options.

3. Font replacement via Magisk (for root devices)

If you have root rights or you have Magisk installed, the process of replacing the font becomes easier and more reliable, and this method works on any firmware, including custom ones (for example, LineageOS or Pixel Experience).
