You can turn that and Face ID off on iOS by mashing the power button 5 times- it locks everything down.
I've always wanted a setting to create a lockdown key and an unlock key. So something like middle-finger to unlock but index-finger to force it into PIN/password only mode. So you can have some convenience of a quick unlock but if an authority figure asks or forces you to unlock it you can one-tap lock it down.
That would be awesome.
In GrapheneOS, a single wrong fingerprint disables fingerprint unlock until the password is entered.
That's not correct. It just says not recognized, and let's you try again. I just tested it. Do you have documentation that it should work the way you said and mine is faulty?
⚠️ WARNING: On android, mashing the power button 5 times calls emergency services.....
On android you can add a 'lockdown' mode to the power menu.
Not on my Pixel 6. 🤷♂️ It just does what I told it to do, namely to open the camera.
Edit: these are some Reddit down votes. I just didn't know I had this feature, and I apparently have disabled it, but I don't remember doing so. Oh well.
Cool, you disabled the gesture. Clearly the default SO setting doesn't apply to you....
I didn't even know it existed. I had to search to find the setting, but I see it exists on my phone and it's disabled. I don't recall disabling it though.
Have to tried? On my Samsung pressing twice does the camera (as I've set it to) but doing 5 times tries to call emergency services.
They disabled it . I don't understand why they even commented. It reads like some weird flex
Thank you for defending me. ❤️ They were correct though. Apparently I had the setting disabled, but I don't remember doing so. Must have been years ago on another phone? And then carried over when settings migrated? I don't know when this feature was introduced. But yeah. It's a thing.
But obviously not universal if you don't have it. Which Android version are you on?
I don't know how it sounds like a weird flex. I was just asking. I don't remember if it was something you could disable or not from when I had my pixel 5.
I did, yeah. Gotta test before commenting, of course. I see I have the setting disabled for some reason. Don't recall disabling it though.
There are two ways you can do this on Android currently, but they're not as quick. You can try to unlock with the wrong finger 5 times and it will stop allowing fingerprint unlocks. Or, you can hold down the power button for 10 seconds and the phone will reboot and also disable fingerprint unlocking.
Android has a similar feature. It's called "Lockdown mode" on the shutdown menu. Locks the phone and turns off any biometric unlocks.
Except it doesn't activate by mashing the power button 5 times. On my Pixel 8, that activates the emergency dialer that will automatically call 911 if you don't cancel the prompt in 5 seconds. I did not know that before. Probably a better use for that feature. It also points out the different ideologies of Apple vs Android.
It does the same thing on iOS, but face/Touch ID is disabled after.
You can turn off the 911 “feature.” Don’t ask me how I know 😅
My wife's pixel 3(?) with a flaky power button had us wake up to cops knocking on the door because of that feature.
You can turn it off somewhere in the settings
On iOS, for SOS, Medical ID, and "slide to power off" you hold power and a volume button. That also disables biometric ID.
"Oh shit, what's happening? NO NO NO!"
Yup, can confirm.
Push and hold to get the power menu on my 7.
On my Pixel 7 Pro, I press the power and volume up buttons simultaneously, then I can click Lockdown. Now my passcode is required to unlock the phone.
In a getting pulled over situation, this works. But do it before you go protest anything. Or better yet, leave your phone at home. You don’t want to be reaching for something while a cop is pointing a gun at you and saying “Hands up!”
Not to mention it's pretty regular to track who is participating by checking the towers in the zone all the people are participating.
Or get a geofence warrant
☞ EFF / Surveillance Self-Defense / Attending a Protest
Didn’t know EFF had this, neat
That's terrifying. So once we have tech to forcibly see inside the brain, that will be legal too?
“You shouldn’t be worried if you have nothing to hide” 🤷♂️
Tap for spoiler
/sYou think it wouldn't xD?
Probably. Wouldn't it be good to have the truth during investigations?
However I think that we really need refine when warrantless searches can occur. Right now many searches seem to be done with very little evidence to justify them. I think this protection should apply to your mind and phone just like it applies to your house. This probably also needs to be considered at border crossings. Right now they have basically unlimited rights for searching what you have on you with little to no evidence.
We should probably also rethink about how the information is shared when there is a warrant. Right now during a trial a huge amount of personal information can be made available. Maybe if it was easier to get precise information less would be needed.
Well, yeah, but the mind is fallible. That's why eye witness testimony usually only gets a case so far, people tend to forget specifics and fill in the gaps without realizing they did.
That is important to remember but it is sort of orthogonal to the point being made. Assuming that mind-reading worked perfectly you can find the truth about what the person believes. In most cases if they think they murdered the person and the gun is hidden behind the oak in their backyard it is beyond a reasonable doubt. I think it is still useful to have the truth about what that person believes, even if we have to remember that their beliefs are fallible.
Do you have to mash it? Or will pressing it normally work?
The only thing I'll mash is that subscribe button
NO
You can also just long press a volume button with the lock button (with a FaceID phone). I find this harder to mess up under stress.
Assuming you have the access to do this, e.g. awake, conscious, not handcuffed, etc. It's safer to just always use a PIN in the first place.
On Graphene/Calyx you can auto-restart the phone after a given time period if it hasn't been interacted with. Recommend turning this on for all users.
What's the name of this feature for GrapheneOS? I'm not finding it.
Try searching for auto reboot, or some sort of extra security settings menu.
