Unknown Sources Before you can download a web application you must enable the Unknown sources feature (enables downloading). Developers can use this option to install non-Play Store applications. 1. From a Home screen, tap Apps ➔ Settings ➔ Security. 2. Tap Unknown sources to active this feature. An informational pop-up displays. 3. Read the message and tap OK to allow installation of non-Google Play applications. When enabled, a check mark appears in the check box. Warning! Enabling this option causes your tablet and personal data to be more vulnerable to attack by applications from unknown sources. Note: If you are notified that you can not download a Play Store application because it comes from an "Unknown source", enabling this option corrects this issue. 231 Credential Storage This option allows certain applications to access secure certificates and other credentials. Certificates and credentials can be installed to the SD card and password protected. 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 a Home screen, tap Apps ➔ Settings ➔ Security. 2. Tap Trusted credentials to display only trusted CA certificates. A check mark displayed next to the feature indicates secure 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.
