The iPhone XR does not have 3D Touch, but relies on a system called Haptic Touch. It offers pretty much the same functionality and, for the moment, it is an exclusive for iPhone XR. Here's how to configure it.
If you are new to the iPhone XR, you may not realize that you have Haptic Touch, and you would not be the first either. Haptic Touch is the replacement of the iPhone XR over 3D Touch, something that most iPhone owners have played and forgotten.
What is Haptic Touch?
Haptic Touch acts as a right click, allowing iPhone XR owners to activate menus and buttons that would normally be unavailable. The activation of Haptic Touch on a notification, for example, presents additional options for handling notifications. Haptic Touch can also be useful in Control Center, where users can tap an icon and hold it down for more granular control of a feature.
To alert users that Haptic Touch has been activated, iOS generates a small vibration to mimic a click.
How to 3D Touch and Haptic Touch Differ
The differences between the two are quite minor, the implementation of the two features being the main difference. While 3D Touch requires firm pressure on the iPhone's display, Haptic Touch keeps them depressed until they feel a haptic reaction.
The differences persist in what you can do with Haptic Touch. For the most part, everything that works via 3D Touch is also possible with Haptic Touch, two notable exceptions. First, you can not access application-based shortcuts from the Home screen. Secondly, Haptic Touch does not support "Peek & Pop", a feature that offers previews of everything from images to URLs. It's the biggest lack of both, but you pay your money, you make your choice.
That said, if you own the iPhone XR, you should at least try Haptic Touch.
How to configure Haptic Touch
Whether you are new to Haptic Touch or a veteran of 3D Touch, open Settings to start the process, then press "General".
Then press "Accessibility". This may not be the most obvious place for such an option, but it's true.
To access the Haptic Touch options, tap the entry for the same name.
The final screen allows you to change the time it takes to activate Haptic Touch, while offering a test button to test the change without leaving the Settings application.
Strangely, Apple has decided not to allow the deactivation of Haptic Touch (which they did with 3D Touch). If you find that you accidentally activate Haptic Touch, try setting "Touch Time" to "Slow" and see if it improves things.
