On iPhones, if you have Face ID enabled, pressing the power button 5 times puts in lockdown mode. This disables the usb port, Face ID, contactless payments, and requires the 6-digit pin to unlock everything. I don’t know if android phones have something similar.
It’s a neat trick for when you think you might get into a “situation”. Also, the cameras still work.
Restarting the device does this on Android. The PIN is required to enable any functionality.
Disabling the USB port is neat, BUT... What if it got instead reconfigured to pretend to be a USB keyboard when connected and then... you know... For research purposes, of course.
It's only helpful where investigation is not worth the time/cost. Unless you use Lockdown mode, they can do full extraction of iPhones via Cellebrite.
That’s the thing about lockdown mode— it’s super-quick to enable of you get into a situation, and you can still use your device with it turned on to, for example, video record an incident that will live-stream or sync to the cloud for later remote retrieval.
And with the usb port disabled, the cops won’t be extracting anything.
It's not fast, but I think we're talking about different things. You are probably talking about SOS mode. The Lockdown Mode requires navigating through a bunch of settings and entering your passcode to enable it.
And port is just one way Cellbrite works. It has many modes which exploit different weaknesses to gain access. Apple finally fixed the biggest one, by finally encrypting the iCloud backup. Before that, all the security measures were defeated by Apple itself, by making a copy of the whole device and leaving it unencrypted...
P.S. Apple only recently were forced to use Universal Serial Bus (USB). So most people are still using Lightning port (Proprietary Serial Bus).
Oh, you’re right, I was confusing what it’s called with something else. But 5x clicking the power button locks the phone down in a basic way, enough to block Cellbrite from breaking in with a usb tool. And having iCloud advanced encryption enabled keeps them out of there, too.
Android also requires the pin after a few attempts and even when changing your location far enough.
Yes, you can enable a similar option on Android, which can be activated when holding down the power button.
Power + volume up is usually how you do it I believe. Holding power down usually just activates an assistant.
On my Sony phone, holding power with the screen on brings up the power menu, which includes Lockdown mode.
Yeah I don't think that's the default on Samsung or Google phones. Could be wrong.
I might have changed that setting. I don't like Google Assistant on my phone since it interferes with my Google Home devices.
nope. default android 12-13 is the screen above posted. Hold power for a few seconds and it'll pop up unless you've changed settings.
Default android is not what most people run. Samsung and Google defaults are assistant.
nope. wife's Pixel 5a and my work pixel 3xl both do this on long power button.
Interesting. It's definitely a Samsung default and I thought it was Google default too.
You can obviously disable it by turning off Assistant but if that's not what you've done then there's more to it than I thought.
How do you shut down your phone? :)
Power + Volume Up?
They mean to press and hold the power button. Which reveals this menu
