Android is traditionally an open system that allows you to mess with the system in all sorts of ways. I've previously replaced the default launcher and I know that you can replace the default lock screen if you want to. But that means that you can install a lock screen that prevents people without your password from making emergency calls, here's the first set of instructions I found Googling it. https://www.thecustomdroid.com/remove-emergency-call-button-android/ https://www.thecustomdroid.com/remove-emergency-call-button-... Normally I feel like it's a strength of the Android operating system that users are allowed to make whatever changes they want, including handing off all responsibility for phone calls to Microsoft or whatever. But in cases like this where users might not understand what that means I wonder how we can put in better guardrails while still maintaining the systems flexibility.
