Apple’s 3D Touch gestures which debuted with the iPhone 6s can be pretty useful for quickly cross-referencing information, calling up shortcut menus, and accessing rich notifications. However, since 3D Touch is a distinct gesture from merely touching and holding your finger on the screen, sometimes it can get a bit tricky to differentiate between the two, such as when trying to rearrange icons on the home screen as opposed to triggering shortcut menus.
Fortunately, Apple has provided a way to adjust 3D Touch sensitivity, hidden away the Accessibility section of your iPhone Settings app. Selecting 3D Touch from here provides three sensitivity levels that you can choose from based on how hard you want to press on the screen to trigger a 3D Touch action, and there’s even a helpful test area so you can try out the different settings. Also, if you find that 3D Touch just gets in the way and you’d rather not use it at all, a switch at the top allows you to turn the feature off entirely.
