    The solution is so obvious that I suspect a conspiracy. Just allow OTHER actions to be performed based on the finger used. Maybe it’s unlock, maybe it’s power-off, maybe siren, maybe factory-reset.

      I’ve been looking forever for an android ROM that does this. Base it on fingerprints and pins.

      Surprised no one has used it to streamline multiple profiles for shared devices either.

    On iPhones, if you have Face ID enabled, pressing the power button 5 times puts in lockdown mode. This disables the usb port, Face ID, contactless payments, and requires the 6-digit pin to unlock everything. I don’t know if android phones have something similar.

    It’s a neat trick for when you think you might get into a “situation”. Also, the cameras still work.

        That’s the thing about lockdown mode— it’s super-quick to enable of you get into a situation, and you can still use your device with it turned on to, for example, video record an incident that will live-stream or sync to the cloud for later remote retrieval.

        And with the usb port disabled, the cops won’t be extracting anything.

          It’s not fast, but I think we’re talking about different things. You are probably talking about SOS mode. The Lockdown Mode requires navigating through a bunch of settings and entering your passcode to enable it.

          And port is just one way Cellbrite works. It has many modes which exploit different weaknesses to gain access. Apple finally fixed the biggest one, by finally encrypting the iCloud backup. Before that, all the security measures were defeated by Apple itself, by making a copy of the whole device and leaving it unencrypted…

          P.S. Apple only recently were forced to use Universal Serial Bus (USB). So most people are still using Lightning port (Proprietary Serial Bus).

            Oh, you’re right, I was confusing what it’s called with something else. But 5x clicking the power button locks the phone down in a basic way, enough to block Cellbrite from breaking in with a usb tool. And having iCloud advanced encryption enabled keeps them out of there, too.
