I can't follow your scenario here. If you really have such threat model that you have to care about the AFU/BFU state of your device. You should rethink how you use it. What you asking for won't help against an adversary you're assuming.

For me it takes exactly 2 sec to restart the device. Power button - restart. And don't ping developers pls

    Nuttso

    In addition to that you could set Auto reboot to 10min (in situations where you have little trust in your fellow humans), as some kind of safety net. It's unlikely that anybody is able to guess your PIN or password in that amount of time.

    Not exactly related but would be good to have a way to quickly delete a designed user profile. Right now you need to go all the way up to confirmation dialog and hold a finger to tap Okay

      Nuttso relying on the screen here is not a good practice imo. i'm really sorry for the ping and you are absolutely right, but a 30 sec timer for the power button is indeed questionable..

        vvf69107 if your threat model is arrest. Which is what i highly assume. You have rethink how use the phone. Make sure that you are the one who is in control about the state your device is in. If you start shaking your phone while they try to arrest you. You might get shot.

          Nuttso how do you ensure this? btw i think you'd rather get shot when using the display than shaking, because you're obviously turning it off.

            Depending on where you're currently residing and the jurisdiction in that country that probably would come down to homicide or murder. So if touching your device, regardless of the motion be it shaking or merely touching, might get you killed isn't the auto reboot timer just the tool you want? 10 min is barely enough to brute force your device. Taking into account that a few minutes may have passed since your last unlock, it would be even less.

              Phead i did not say somebody wants to kill me for using my phone. i just want to be able to turn off or restart quickly/ without a display.

              30 seconds power button press wtf?!

              even if it's not an emergency.
              it isnt even sufficient for restarting the device when having blackscreen, which is a common issue when using video players on grapheneos.
              (couldnt find the thread unfortunately, but the fix is to enable screen activation on pickup)

              who expects to hold the button 30 seconds?
              whom does it help?
              i've never seen something like this on my past phones.

                This action is standard on most phones. It's the same with computers. If you hold the power button for a certain amount of time it will hard restart or shutdown completely. It's very useful when the OS has crashed, for example.

                  yes it is!
                  but it takes way to much time to press the button until it's off.
                  should be much quicker especially on an OS optimized for security and high thread models.

                  It does not take 30 secs. I hold my power button for 1 second and then press lockdown or restart. Takes a total 2 seconds for me for the phone to restart.

                  If that's not enough. Stop using a phone for whatever someone is trying to kill you for.

                  Can I recommend using a note pad, pencil and a secret code then?

                  It sounds like in your extreme case, the only way to win is not to play.

                  Well, you could start to work on a feature request for something similar to Apple's emergency ... thingy (press 5 times the Power button to enter emergency mode). So, in your case this feature would be configured to restart/power off your phone whilst being in your pocket. As long as your expectations are clearly expressed maybe you and the devs eventually enter a fruitful discussion about this topic. Or you come up with other solutions.

                  But, since you and someone else mentioned that fiddling with your phone while being in difficult situation could be dangerous, I do not think that having your hand in your pocket while talking to/facing law enforcement is a good idea.

                    It seems that this fellow vvf69107 is experiencing difficulties with his smartphone display, and is looking for assistance in turning off the device. However, he lacks a functional display, which creates a bit of a challenge. To clarify, some members of this community believe that he has a working display, but this is not the case.

                    In my personal opinion, I find it quite impractical that one needs to hold down the power button for 30 seconds in order to power off the device. It seems like an unnecessarily long time that could cause frustration for users without a functioning display. Perhaps there could be an alternative solution that would make the process more efficient and user-friendly?

                      [deleted] finally someone who understands me!
                      to clarify again:
                      my screen is working, but there is a bug with video players where you can get a blackscreen really often and this is how i discovered the 30 seconds button press. (at first i thought the phone was dead)

                      in any situation this is a ridiculus amount of time to press the button and wait..

                        vvf69107 how do you ensure this?

                        By making sure, that for the currently needed time to restart it, you remain untouchable while using it. Security is not a phone. It's a concept. Relying on sensors and a button isn't the right approach. This will never be implemented

                        vvf69107 in any situation this is a ridiculus amount of time to press the button and wait..

                        I might be missed something in that thread, but where did you find/assume the 30 sec. power button press is intended to be for an emergency? I see it as an option due to an unresponsive phone/device with a sealed battery.
                        Sorry, I do not mean to put more fire in that discussion.

                          The behaviour you desire is too niche to be implemented by the OS devs. They would need to spend a lot of time making a lot of options.

                          You want custom automation. I prefer Tasker for this kind of thing. You can program gestures and long press of volume keys (not reliable with screen off).
                          My approach is a tasker automation that counts incorrect PIN/Password attempts and runs a task (like reboot after X attempts). For me, this is better than just throttling attempts. You can also create a decoy app icon (say crypto wallet) on your home screen that reboots the phone (useful if you're mostly worried about being robbed by someone snatching the phone faster than you can lock it).

                          There is also a Shake trigger which can be combined with being on the lockscreen. And you can geofence it so it only happens when away from home/work.
                          Lots of options for you.
