The physical power button is hard to press. Isn't there any other way to turn off the screen, without using external hardware like a cover and not using Assistive Touch?
Turn off button in the Control Centre: Android allows third-party apps to add custom actions to the quick settings. Is something like that not allowed in iOS? That is, there is no way to add a turn off button in the Control Centre?
Turn off using the physical home button: It seems long press is for Siri, but I do not use Siri. Can't I assign long press to turn off the screen? How about double click to turn off the screen? It seems that I could set an action for a triple click, but turning off the screen was not available.
Any app to turn off the screen?: On Android, there is an API to lock the screen or turn off the screen without locking (on newer Android versions), so there are apps that add widgets to turn off the screen. There is no such API on iOS, so a third-party app solution is not possible at all?
Any inbuilt gesture to turn off the screen? I don't know, something like 5-finger tap or 5-finger swipe down, etc.
