Somewhat off the subject of this post, but I believe we lost something when calling for help stopped being as simple as grabbing at the wall and punching a couple buttons. What are children supposed to do these days to call 911 or 999?
On iOS, just hold the button you would use to turn the phone off, but hold longer, it will loudly count down to 0 and call emergency services. You can also press the side button 5 times and it will call without you having to hold the button pressed. Works on iPhone and Apple Watch.
Funny enough, my current phone is absolute garbage, and I've managed to accidentally call 911 multiple times because the phone will simply fail to render the lock screen at times, but all controls are still active.
