This is according to a report from MacRumors where they have cited a research note from Barclays analyst Blayne Curtis and his associates. Curtis and his associates had a meeting with some suppliers that are part of Apple’s supply chain where they found out that the 2019 iPhones are expected to do away with 3D Touch.
This isn’t surprising because while 3D Touch did hold a lot of potential, it was never really quite obvious as to what it could do. Users kind of had to figure out which apps could do what and it was never really a consistent experience. Instead, it has since been rumored that Apple could move to the use of Haptic Touch that debuted with the iPhone XR.
Haptic Touch was used as a substitute for 3D Touch on the iPhone XR and could be seen as a mix between the long-press and 3D Touch, where long-pressing on an object could activate certain features while giving the user some feedback.
