Allow Installation of Third-Party Programs
By default, you can only install 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. Tap
>
>
2. Tap Security.
3. 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.

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.
Notes:
Some apps such as your browser or email client let you install certificates directly in the app. See
n
the app's help for details.
You must set a lock screen PIN or password before installing a digital certificate.
