- Android 7.0 (SDK 24) or more.
- Shizuku/root or ADB to grant one of the needed permissions for changing the device's locale settings (
android.permission.CHANGE_CONFIGURATION
).
Some OEMs, particularly Xiaomi with MIUI/HyperOS, limit users to selecting only one language or locale. This restriction can lead to issues, such as apps displaying incorrect characters due to Han unification, where characters in one language may appear in another. For example, without Japanese added as a locale, apps may show Chinese characters instead of Japanese ones.
