Insufficient for Emergency

I'm missing the option to encrypt the phone quickly or fully lockout of the secondary profiles.
As well as an option to disable pin highlighting.

As well as an option to disable pin highlighting.

That is supposedly coming with Android 14.

How quickly? Holding power button and pressing reboot will do that for you.

vvf69107

matchboxbananasynergy and that's the problem. we shouldn't rely on using the display and 30 seconds of power button press is unreasonable.

vvf69107

a setting to adjust this time (from the main profile settings ofc) would help a alot.

@"matchboxbananasynergy" @GrapheneOS" Seriously whe need to get in BFU quicker and more accessible..

holding the power button for 2 to 3 seconds when being robbed can be hard enough.

I'd be open to holding Power Button + Shake the Device to lock it down/reboot it. That'd be a nice shortcut.

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

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.

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..

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?

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

vvf69107

evalda swapping from power button menu would be nice

toltevuydo

evalda I agree evalda. it should be easier to delete a user profile

Nuttso

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.

vvf69107

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.

Nuttso

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

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.

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.

vvf69107

Panda-na

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.

Room101

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

Phead it's already been mentioned on github and i dont know what to explain more about it.

i'd propose 2-3 seconds button press until shutdown or a setting...
