How To Use Trusted Credentials On Samsung Galaxy S4

Learn how to use the trusted credentials on your Samsung Galaxy S4. If a certificate authority (CA) certificate gets compromised or for some other reason you do not trust it, you can disable or remove it.

  • From the Home screen, tap Apps > Settings > More tab > Security.
  • Tap Trusted credentials.
  • The trusted credentials screen has two tabs:
    • System: Displays CA certificates that are permanently installed in the ROM of your device.
    • User: Displays any CA certificates that you installed, for example, in the process of installing a client certificate.
  • Tap a CA certificate to examine its details. A scrolling screen displays the details.
  • Scroll to the bottom of the details screen and tap Disable to disable a System certificate or Remove to remove a User certificate.

Note: When you disable a system CA certificate, the Disable button changes to Enable, so you can enable the certificate again, if necessary. When you remove a user-installed CA certificate, it is permanently deleted and must be re-installed, if needed.

  • Tap OK to return to the certificate list.
  • When enabled, a check mark appears in the check box.
