On iOS you can just hold the side button and one of the volume buttons to bring up the SOS menu, if you keep holding the buttons it’ll sound an alarm, do a countdown, and call the emergency services. You don’t actually need to interact with the screen. Obviously this means you’ll need to be able to squeeze your thumb and another finger together, but a phone with buttons would require you to be able to operate that somehow too.
I think you could also try to ask Siri if that’s enabled.
I’ve no idea about Android but I’d assume you can do something similar there.
holding the power button brings up the emergency menu. You can also use the same menu to lock your phone down so none of the police scanner software works.
Holding the power button brings up Google Assistant on my Pixel 6. It does the same on my iPhone.
What version of android are you running?
Lol on Android that same shortcut takes a screenshot hahahaha… I don’t know why that’s so funny to me.
