We're all meant to test our smoke alarms once a month. We don't.
All it takes to test is just one button press. We're good at pressing buttons, we press the buttons on our phones thousands of times a month.
Receive a notification showing the link between how much you press your home button and how little you test your smoke alarm. Ignoring the notification prompts a second one, whilst your screen appears to burn
The more you ignore the more your screen is taken over. To stop the fire you need to test your smoke alarm so that Siri can hear.
