As a part of cost-cutting, most of the Samsung Galaxy M series smartphones doesn't support Good Lock, Samsung Pay, Samsung Pass, Secure Folder, Bixby Voice/Routines, Easy Mode etc. due to inexistence of Samsung Knox Security & It's a hardware absencey so it can't be added through future updates. & built-in "Screen Recorder" feature is a Samsung's flagship feature so currently you can use third party apps to use this feature form "Play Store"
