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.
