We take privacy very seriously around here. When it comes to protecting the information on your phone, you’re in good hands. Your phone offers numerous security features to keep your data secure from others. You can scan for potential threats or simply enable a security feature.

Note: Available screens and settings may vary by wireless service provider and software version.

Scan your phone

You can scan your phone for threats and resolve any issues right from the Security and privacy screen. Navigate to and open Settings, then tap Security and privacy, and then tap Scan at the top of the screen. The first time you visit this feature, you may need to tap Dismiss on the notification. Then, tap the following results to resolve the issues if necessary:

  • Lock screen: Create a PIN, Pattern, or Password for your device to restrict entry and protect your data. Tap Lock screen, then tap Screen lock, and then select your desired option. Follow the on-screen instructions to set it up.
