Verify Apps
This feature allows you to either block or warn you before
installing apps that may cause harm to your phone.
1. From the Home screen, touch Apps ➔ Settings ➔
More ➔ Security.
2. Touch Verify apps.
A check mark is displayed to indicate it is active.
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 Home screen, touch Apps ➔ Settings ➔
More ➔ Security.
2. 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.
3. Touch a CA certificate to examine its details.
A scrolling screen displays the details.
4. Scroll to the bottom of the details screen and touch
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. Touch OK to return to the certificate list.
