View System Credentials
In the Credential Storage section you saw in Figure 6, you can show trusted credentials and install certificates.
You can view, add, and remove trusted credentials installed on your device by tapping Trusted Credentials. The Trusted Credentials screen appears as shown in Figure 7 and shows you all the credentials on your system that tells your Tab 4 that the apps and services that use these credentials are trusted and can operate on the device.
Figure 7 Swipe up and down in the list to view all the trusted credentials for the system.
View the entire list by swiping up and down within the list. Each installed credential contains a checked checkbox to the right of the credential name, which means that the credential is currently installed. If you want to remove the credential, tap the checkbox.
Next, you see the Security Certificate window that shows you information about the certificate; you can turn off the certificate by tapping the Turn Off button at the bottom right corner of the window. If you just want to view the certificate information without turning it off, tap the OK button at the bottom of the window.
