iPhones do this too. Hold the lock and volume down button until your phone buzzes, to get to the SOS/reboot screen. Once that screen is activated, it’ll disable biometrics until the passcode is entered.
You can even take photos/videos with the locked phone, and the recordings won’t be able to be deleted from your iCloud until the passcode is entered. Handy for recording cops. Cuz even if they take your phone and delete the recording, it’ll still sit in your “Recently Deleted” for 30 days. And while the phone is locked, they can’t access that Recently Deleted folder to permanently wipe it. So you can just access your iCloud account from any computer and recover the “deleted” footage.
