Possibly, however 3D Touch can also do more than Haptic Touch (or basically long press).3D Touch is an example of over engineering something when a much simpler and just as functional method already exists. 3D Touch is on its way out.
They work differently and while some things that they can do can be similar, there are other things that 3D Touch can do that can't really be done with Haptic Touch (or long press/touch and hold).I have an iPhone 6 Plus(iOS 12.1.4). The iPhone 6 Plus does not have 3D Touch. But the iOS12 have Press and Hold.
So how is this happening? What's the difference between 3D Touch and Press and Hold?
