Use Haptic Touch to Get More Options
Haptic Touch is a feature that came to replace 3D Touch. This feature lets you press and hold certain apps or controls on your iPhone to get more options.
You can use this in many different places on your iPhone. If you go to your Control Center and use Haptic Touch by long-pressing a control, you’ll get a bunch of extra options. For instance, if you press and hold your flashlight control, you’ll have the option to adjust the brightness.
Likewise, if you press and hold an app, you might get extra options you can use without actually opening the app.
