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 a Home screen, touch 

 Apps ➔ 

 Settings. 

Under Personal, touch Security.

• Touch Storage type to set a storage type for credential 

contents.

• Touch 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.

• Touch a CA certificate to examine its details.

–

A scrolling screen displays the details.

–

Scroll to the bottom of the details screen and touch 

Turn off to disable a System certificate.

2. Touch OK to return to the certificate list.

3. Touch Install from device storage, then choose a 

certificate and follow the prompts to install encrypted 

certificates stored on the USB storage.

You must have installed a memory card (not included) 

containing encrypted certificates to use this feature.

Note: If you have installed encrypted certificates, touch Clear 

credentials to erase the credential contents from the 
device and reset the password.
