# Install CA Certificates

### For Android 12:

1. Navigate to Settings > Security > Encryption & credentials.
2. Select Install a certificate > CA certificate.
3. Follow the on-screen instructions to complete the installation.

### For Other Android Versions:

1. Save the CA certificate to a TF card.
2. Insert the TF card into the terminal.
3. On the terminal, go to Settings > Security > Install from SD card.
4. Select the CA certificate from the TF card.
5. When prompted, enter a name for the certificate.
6. Set a lock screen PIN if required.
7. A confirmation message will display upon successful installation of the CA certificate.

### Important Notes:

* Third-party apps cannot install a CA certificate on the terminal programmatically without UI interaction for security reasons. Only system APKs have this capability.
* It is crucial to follow these steps to ensure the secure and correct installation of CA certificates.
