Trusted Credentials
If a certificate authority (CA) certificate gets compromised or
for some other reason you do not trust it, you can disable or
remove it.
1. From the main Settings screen, tap Security.
2. 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.
3. Tap a CA certificate to examine its details.
A scrolling screen displays the details.
4. Scroll to the bottom of the details screen and tap Turn
off to disable a System certificate or Remove to remove
a User certificate.
Caution! When you disable a system CA certificate, the Turn
off button changes to Turn on, 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.
5. Tap OK to return to the certificate list.
When enabled, a check mark appears in the check box.

Note: You must have installed a memory card containing
encrypted certificates to use this feature.
1. From the main Settings screen, tap Security.
2. Tap Install from phone storage, then choose a
certificate and follow the prompts to install.
