Widgets came out for iOS like 9-10 years after it came out on Android. I don’t think that’s “copying” unless Apple was desperate to have done so in a short space of time not this longWidgets, the app tray and Picture in Picture say hello. Wireless charging says hello.
I don’t know when app tray came out for Android
As for Picture in Picture iOS in fact had it before Android though it was only for iPads (iOS 9) until iPhone/iPod Touch this year so that doesn’t count as Apple copying Android 😁😁
