Check Contents

Review the configuration to determine if the Samsung Android devices are locking the device display after 15 minutes (or less) of inactivity.

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

On the management tool, in the device password policies, verify "max time to screen lock" is set to "15 minutes" or less.

On the Samsung Android device:
1. Open Settings >> Lock screen and AOD.
2. Verify "Secure lock settings" is present and tap it.
3. Enter current password.
4. Tap "Auto lock when screen turns off".
5. Verify the listed timeout values are 15 minutes or less.

If on the management tool "max time to screen lock" is not set to "15 minutes" or less, or on the Samsung Android device "Secure lock settings" is not present and the listed Screen timeout values include durations of more than 15 minutes, this is a finding.
