You can do this on any android. Ive had macros like this setup on all my android phones for nearly a decade!
Download an app called MacroDroid, it will probably already have templates setup for SOS messages, where you can add whatever else you want, such as updating your current location then sending it via text or email to someone, along with the pictures.
It is basically an automation tool that will do all this in the background after you activate it, which could be anything like the 3 clicks of the power key, or shaking the phone, or drawing a symbol or letter on the screen even when its off (gestures). Theres no need to wait for Samsung or any other android manufacturer to integrate it into the OS, its existed for years...
Wirless charging came out on both phones at the same time, the discovery was magnets in the wireless charger and to be fair while widgets are so old on Android the apple ones look better, most probably since widgets haven't been changed since they came out
