3D Touch technology in Apple smartphones appeared back in 2015, along with the release of the iPhone 6s and iPhone 6s Plus. After that
What does it mean
A mention was found in the second beta version of Android Qnew feature - Deep Press. Like 3D Touch, it allows you to determine how hard you press on the display. That is, instead of holding your finger on the screen for a while, you will simply need to press harder on it.
The documentation says that forceful pressing will be used to bring up the context menu of applications, as well as quick access to individual Android functions.
However, it is not yet clear how this will work.For example, the iPhone has special sensors for full 3D Touch operation. Whether Google will need them is unknown; the company may be able to get by with just the software.
By the way, Apple itself has recently abandoned this technology, and many users consider it unnecessary. For example, the iPhone XR no longer has this feature.
