3D Touch is an iPhone feature that lets you perform an action by pressing more deeply into the touchscreen than your normally would. Now it looks like Android may be getting a similar feature.
Android Q documentation suggests that a new feature called a "Deep press" will bring 3D Touch-like functionality to Android. Inside the "MotionEvent" documents that are responsible for how touchscreens, styluses, and mice act, there's a mention of a "deep press" and how an app should handle it:
"Classification constant: Deep press. The current event stream represents the user intentionally pressing harder on the screen. This classification type should be used to accelerate the long press behaviour."
3D Touch on the iPhone can be useful as a shortcut to a specific action or section of an app. Deep presses should be a similar time-saving feature, letting you more quickly access a feature that's normally hidden behind a long press. Once Android Q is released, we'll have to wait and see which hardware makers decide to take advantage of the new deep press functionality.
