Anthony is approaching Customs in a foreign country and and is immediately asked for his Android phone. What can Mike do very quickly to help secure his phone?

Enabling Lockdown Mode is the quickest and most effective action Anthony can take. This mode immediately disables fingerprint and facial recognition unlocking, requires the PIN, pattern, or password to unlock the device, and hides notifications on the lock screen. This prevents unauthorized access via biometrics and keeps sensitive information from being displayed. Smashing the phone or performing a factory reset are destructive and irreversible actions that would lead to data loss and device damage, which is not the goal. Hiding the phone is not a practical or reliable solution when directly asked for the device by authorities.
