Review Samsung Android configuration settings to determine if the mobile device has the screen lock timeout set to 15 minutes or less.

This validation procedure is performed on both the management tool Administration Console and the Samsung Android device.

On the management tool:
1. Open the device password policies.
2. Verify "minimum password quality" is set to "Numeric" (or better).
3. Verify the "max time to screen lock" is set to "15 minutes" or less.
