Why do users change font size to Xiaomi?
Xiaomi’s MIUI-enabled smartphones offer flexible text display settings, but not all users are aware of all the options available.

It is important to understand that changing the font size affects not only system applications, but also most third-party programs if they support Android system settings. However, some applications (such as Instagram or TikTok) may ignore these settings using their own fonts.
