You can turn that and Face ID off on iOS by mashing the power button 5 times- it locks everything down.
⚠️ 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.
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
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 😅
On iOS, for SOS, Medical ID, and "slide to power off" you hold power and a volume button. That also disables biometric ID.
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 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.
"Oh shit, what's happening? NO NO NO!"
Yup, can confirm.
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?
Do you have to mash it? Or will pressing it normally work?
The only thing I'll mash is that subscribe button
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.
