Do all Android phones come with these emergency features?

I have recently bought an ASUS Zenfone 4 Max (ASUS_X00HD) phone. It comes with several emergency calling “features” with seemingly no option to disable them. There is an emergency button on the power menu below the restart button (similar to this), that people who have the same phone say immediately dials the emergency services. People also say that – at least with phones in the same series – pressing the power button three times accidentally also makes an emergency call. Having to constantly watch out not to press the wrong button makes using the phone so stressful that I’ve decided that I will buy a new one. My question is: Is this a “feature” that all newer Android phones have? Is this something that is implemented in the common Android operating system, or is this just a feature that ASUS added to their phone(s)? Is there a way of knowing which phones do not have this? If you know of Android phones that do not have this, that would also be really helpful to know.
