iPhones prior to the iPhone 11 used to be able to sense the pressure you touched with on the display, and a firm touch had a ton of neat but hard to discover user interactions, from previewing links in safari without opening them to preventing accidentally hitting the flashlight on the lockscreen on X/XS by requiring a bit of pressure.
One of the best (imo) features was the ability to move the cursor in any direction by dragging firmly anywhere on the keyboard. No delay, no press and hold, just instant access to a cursor. The new "haptic touch" way of doing this makes it difficult if not impossible to scroll down, and needing to press and hold ensures it will always be slower.

Must be tons of fun to use with Swipe-type input (aka Flow, etc)
