What to do if an unknown source warning prevents app installation on Xiaomi phones or pads?
If an unknown source warning prevents app installation on Xiaomi phones or pads, please refer to the following information:
1. Ensure the app is downloaded from a trusted source such as the Google Play Store and that the installation package is compatible with the device.
2. If the system prompts that installation from an unknown source is prohibited, enable the related permission for the App used to download or open the installation package by going to [Settings] >> [Security & privacy] >> [More security & privacy] >> [Special permissions] >> [Install unknown apps].
3. If installation is still blocked, check whether Google Play Protect, the system security feature, or parental controls are preventing the installation. Follow the relevant security prompts and verify the app's safety before proceeding.
4. Restart the device and try installing the app again. If the issue persists, check whether the installation package is corrupted or incompatible, and download a valid version from the official source.
If you are still unable to install it, please contact the app's developer for further assistance.
