+
+Manual test steps:
+1. Enable app pinning and disable "Ask for PIN before unpinning" setting
+2. Pin an app (ie: Settings)
+3. Lockdown from the power menu
+Observe: user is brought to the keyguard, primary auth is required
+to enter the device. After entering credential, the device is still in
+app pinning mode.

+Test: atest KeyguardViewMediatorTest
