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.

vvf69107 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.

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.

          I know that the 30 seconds are not made up for security and relying on a button is not an option.
          I just don't see a reason why someone should wait this long to restart. there is no benefit right?

          in some situations it's an advantange even in terms of security. which of course doesnt mean it should be the whole concept on how to protect you data.

            vvf69107 What time period would you suggest? 5 sec would be good. Not to short not to long. If you agree open a feature request on GitHub. I don't see a problem shortening this period.

              Nuttso personally i think 2 - 3 seconds would be the sweet spot between not shutting down by accident when opening the power menu and being able to restart quickly.

              Is there a way to contact you? I have read you are working with people on the encro case. I am "kind of" doing the same and I thought maybe we can help each other out.

              Let me know if its possible. My email is therealbunnygame@proton.me. I hope to hear from you.
              Cheers

              Nuttso Hi, what is the probability that experts/authorities crack a smartphone with a four-digit pin? It is a Pixel6 with GOS in BFU condition. Can the waiting time be bypassed with special tools even with GOS if the wrong pin is entered several times?

                @vvf69107 I am surprised people don't understand what you are getting at.

                If you are about to get arrested, you may have time to put your hand in a pocket and hold down a button for 5 seconds and slowly remove your hand. That's not a lot of motion and may not get you hurt. Also you may notice something prior to an arrest: you might hear noises that are unusual or see something that makes you think there could be a possible arrest. You can't take out a phone and start pressing buttons and that point to initiate a process. It could also make an arrest more likely to do that if you aren't sure what's going on and make it harder to deny you didn't just do something that might be illegal in some countries. You might have time to hold down a button for 3 seconds.

                Having a 10 minute auto-reboot option is not practical for normal use and a long password. Any sort of good password is going to be long and a pain in the ass to type in each time. Most users may want the Owner profile to have a difficult password and other profiles that are less important to have an easier password for easy usage. A 10 minute auto-reboot will force you to keep logging into owner with a harder password again and again. A 10 minute auto reboot also relies on anyone doing an arrest not having an exploit for that situation and they might have an exploit for that and just don't tell people. An adversary may claim that an arrested person has an easy to guess a password like "fuckoff" and the suspect was not very good at making passwords when the password was really 10000 characters and the adversary doesn't want to give a way their exploit. People in law enforcement do lie at times including to the public. Arrested people with long sentences do not have a way of blogging about how they had great OPSEC and their adversary is lying about how they bypassed that and their password was never "fuck off" nor do they likely care at that point to warn others. For people with a high threat model using Profile 2 that resets every 8 hours of inactivity, they want to be able to shut down the phone faster than 30 seconds.

                5 seconds is much too long. It should be 2 seconds. 30 is very bad.

                It's sketchy that people don't grasp your initial concern.

                  Thanks for the quick reply, I'm not an expert, but the article is written in very general terms, it doesn't explicitly say it's Titan M2 chip, it's also unclear what is meant by cryptophones, don't the encryptions of the different operating systems differ? For example, Calyx and Graphene are not the same.
                  Which device did the murderer of Peter R. de Vries have? Wich OS? I read that the victim died in July 2021, the TitanM2 came out later as far as I know. Whether the NSI also cracked the dedicated Titan M2 is the big question.

                    It does not matter whether it was the 1 or 2. If one could be bypassed, the successor can also be bypassed at some point. An alphanumeric password is mandatory. 192bit + entropy

                    vvf69107 how, where, and why do you keep getting this arbitrary 30 seconds from? You have a defective device.

                    It takes roughly 7 seconds maybe 10 holding power and volume+ and the phone reboots.

                    You've been given the auto reboot, which goes to as low as 10 minutes. I'd have to agree, if your threat model is that dire you should really reconsider how you use the Device. You have options you just don't find them fast or 1-click done approved.
