For Android, in the notification shade, you can hit the power button and there should be an option called “Lockdown” which prevents biometrics from unlocking your phone, just like when it first boots.
There’s also app pinning (has to be enabled in settings) where you can lock an app in the task manager and clicking the bubble at the top and select “Pin”. You can’t swap apps or go back to the home screen without password/biometrics.
Different models also come with the quick trigger for lockdown so don’t actually have to go into the menu and tap it. You just have to look in the settings under Security to find it, usually.
But realistically speaking, the simplest thing to do with Android is just turn it off. Hold the power button for a few seconds, it shuts down, and when they try to boot it back up it will demand a pin code first.
