Please stop acting like Apple "invented" such a feature. "Apple 'found' a brilliant solution". Yeah, it "found" it in the Android feature set. Android has had "Smart Lock", which allows you to unlock your phone by BT-connected wearables like watches and earphones for years. It also offers on body detection, and trusted location unlocking. And don't bother making the usual excuse for Apple copying that the Android' version was somehow defective and that Apple "perfected" it.
Both OSes and ecosystems have developed terrific unique features that the other has copied since the beginning of smartphones. Andorid copied Apple much more early on. For the last few years, iOS has copied Android much more. Yin and yang.
