3D Touch offers the ability to differentiate between types of touches and taps. It also performs different functions. Directly from the homescreen, it lets users jump to certain sections of the app.
3D Touch technology is essentially a derivative of the Force Touch technology used which Apple uses in its Apple Watch.
Users can update status, upload existing photos and videos and take photos and videos for sharing on Facebook without opening the app by force tapping the Facebook icon on the homescreen.
According to WhatsApp, users can now quickly scroll into videos, links, pictures, contact cards, and locations they send and receive in chats. In other words, with a light touch or peek, users can preview content and open them with a harder touch.
On Facebook owned photo-sharing app Instagram, 3D Touch is available too.
