Personalizing a smartphone interface is not just a fashion nod, it’s a way to make interaction with the device more comfortable and enjoyable. Owners of Xiaomi, Redmi and POCO gadgets often wonder how to replace the standard system font with something more unique or simply more readable.

You can use the built-in tools of the system, which are safe and simple, or go the more difficult way, installing third-party files in the.mtz format. It is important to understand that improper installation of custom fonts can lead to visual bugs or even problems with the interface load.
