Stop Using Your Face or Thumb to Unlock Your Phone
Stop Using Your Face or Thumb to Unlock Your Phone
The laws surrounding 5th Amendment protections and biometric passwords are still undecided, so just turn it off.
You're viewing a single thread.
Last week, the 9th Circuit Court of Appeals in California released a ruling that concluded state highway police were acting lawfully when they forcibly unlocked a suspect’s phone using their fingerprint.
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?
Sorry, I misremembered, it's 5 times instead of 20: more secure fingerprint unlock
⚠️ WARNING: On android, mashing the power button 5 times calls emergency services.....
On android you can add a 'lockdown' mode to the power menu.
Thanks for this, didn't know this was an option.
on my phone lockdown mode is found by pressing side button and power up at the same time, then selection lockdown from the menu
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.
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
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.
Right, correcting your incorrect information is "weird flex". What are you, five?
On my Mi Max 3 it does not work as well. In "configure buttons" section of menu there is no call emergency number action, neither is there press [any button] five times trigger available. So clearly the function your phone has is not universal. What a wild world do we live in!
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?
Which Android version are you on?

Ah, that's probably why, eh? Android 10 is quite old, right?
might be. might also be miui thing, i don't know.
the fact remains that (android does x) does not equal to (some subset of android does x)
edit: seems the function was added in adroid 12 - https://arstechnica.com/gadgets/2023/06/uk-police-blame-android-for-record-number-of-false-emergency-calls/
which means that as of right now it is available to 60% of android users - https://gs.statcounter.com/android-version-market-share/mobile/worldwide/
Yeah 60% is far from every device lol. But it's still a good warning I guess. 😅
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.
It's not a flex... 🙄 I was just confused about how it seemed so established that this was an "Android" feature, so should be activated on my phone too, but it isn't. And now that I see I have the functionality disabled but people say it's the default, I'm even more confused because I don't remember even seeing this setting. 🤷♂️
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.
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
Yeah, I poked around in the settings that afternoon to make sure it didn't happen again.
On iOS, for SOS, Medical ID, and "slide to power off" you hold power and a volume button. That also disables biometric ID.
Push and hold to get the power menu on my 7.
On my 8, that just activates the Google assistant. To get to the power menu, you have to press power (oddly named button, to be honest) and vol up at the same time. But these are active acts that you have to think about and verify to make sure they did what they are supposed to. Mashing the power button 5 times is succinct. I don't have to guess how many seconds I've waited. I don't have to feel to make sure I'm hitting the vol up instead of vol down accidentally. I count 5 times, 6 to make sure, and I can drop it while being certain that it's going to call 911. That's what I want in an emergency. A quick distinct action that requires no guessing to make sure it works. It makes sense once you stop and think. Nothing else about the power button makes sense, but at least that part does.
Try system - gestures - press power button. I have the choice of the power menu or the digital assistant.
I actually didn't know that was changeable, one of my most hated "features" of my phone that it wants to bring up an AI assistant I'll never use and didn't ask for when doing something that has brought up the power menu on every phone I've ever owned
I could do that...but then I lose easy access to the assistant. I could set up the tap on back function, but that doesn't work when it's in a holder in the car. There are no options that I can find that would let me assign the assistant to open on power + vol up. Unfortunately these phones aren't as customizable as as I'd like them to be. Or at least not by default, but I don't want to go through the trouble of flashing a new OS yet.
I use, "hey Google," but sometimes my car tries to answer and it doesn't know as much stuff.
"Oh shit, what's happening? NO NO NO!"
Yup, can confirm.
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.
On my ditto (running GrapheneOS), the Lockdown option is accessible through the regular power button menu. When I press power+volumeUp it switches to silent mode. I don't know if/where I changed this, since I can't find the options when searching in settings.
EDIT: I just found it - in Settings > System > Gestures > Prevent ringing. I can either set power+volumeUp to mute the phone, or vibrate only. Nothing about the Lockdown option, but having it in the regular power button menu is good enough for me.
If by "regular power button menu" you mean holding the power button for a couple seconds, that was changed at least on pixel devices to bring up some bullshit called "Gemini", some AI from googie that I never got a chance to say no to. Power + volume up is now how we get to the power menu, because of course they would change the function everyone uses occasionally to a more obscure combination without notice
I was mowing my lawn and learned about that feature. A nice ladies voice came through my bluetooth headphones asking if I needed help lol. You can change what the button spam does and I changed it to call my mom instead.
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

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 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.

to be fair to the current justice system, a lot of times you can just hit the courts with "excuse me sir, this was unwarranted" and assuming it was actually unwarranted, they should overthrow it immediately.
Not if it comes with a level of invasiveness that is unforgivable it wouldn't be.
Forcibly invading someone's mind after they were convicted beyond reasonable doubt would make you a monster.
Most trials and discoveries are already incredibly invasive. I don't really see why the mind should be treated much differently. I would rather define what is acceptable evasiveness generally than different for mind vs written down in my diary.
Also why would you do this after they are convicted beyond reasonable doubt? This should only be done when required to reach the conclusion. Just like avoiding physical searches you can just plead guilty if you don't want to be investigated.
If used properly this could actually be less invasive. Imagine a quick check of some facts that you believe with an automated machine that only returns the basic required information and you could be removed from the suspect list before other searches need to be done (like lawyers searching through your emails or personal notes).
I agree that this is a very dangerous thing to consider, and it needs to be applied very carefully. But I don't think it is in the abstract any more morally wrong than the current methods of evidence gathering that we currently do. In many ways it could potentially be less harmful to the person being investigated. However it will be impossible to know for sure until we know how exactly this technology (when it is developed) works.
No, mind reading is a hundred orders of magnitude more invasive than any possible search.
There is no possible scenario where it could ever possibly be justified or excused. Your brain is unconditionally sacred. There is no possible theoretical version of such technology that could ever not be pure, unforgivable evil to use without completely uncoerced consent.
Do you have to mash it? Or will pressing it normally work?
The only thing I'll mash is that subscribe button
NO
Pretty sure Apple would replace the buttons with pressure sensors – not for user comfort but so that they are no longer replaceable with OEM parts and can be serialized. They did literally this with Macbook sleep sensors.
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.
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.
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.
Just hold volume up and power for 3 seconds.
Came here to say that! Glad it’s getting around.
