Allow Installation of Third-Party Programs

By default, you can install only programs and games downloaded from Google Play. The
Security menu lets you allow installation of non-Play Store apps on your phone.
To allow installation of non-Play Store apps on the phone:
1. With two fingers, swipe down from the status bar, and then touch
2. Select the Unknown sources option.
Important: After installing the app, go back to Settings > Security and make sure to clear the
Unknown sources option. This can help protect your phone from installing other insecure apps
from the Web.

Work with Certificates

Use client and Certificate Authority (CA) digital certificates to enable your phone to access VPN
or secured Wi-Fi networks, and also to provide authentication to online servers. You can get a
certificate from your system administrator or download it from sites that require authentication.
Note: Some apps such as your browser or email client let you install certificates directly in the
app. See the app's help for details.
Install a Digital Certificate
Note: You must set a lock screen PIN or password before installing a digital certificate.
1. Save the certificate file in the root folder on your phone.
2. With two fingers, swipe down from the status bar, and then touch
3. Touch Install from storage.
4. If you have more than one certificate in the root folder, select the certificate you want to
install.
5. Enter a name for the certificate and touch OK.
