In iOS 10, Apple tweaked the Touch ID unlock process on iPhones and iPads, requiring a press on the Home button before scanning your fingerprint. Many users miss the original seamless method of simply resting a finger on the sensor.

Apple's rationale? It lets you glance at lock screen notifications, given Touch ID's speed. If you prioritize speed over previews and want the pre-iOS 10 behavior, enable a simple setting available in iOS 10 betas and beyond.
Sometimes the classic way works best. To restore instant unlocking by just placing your finger on the Touch ID sensor, open Settings.
Scroll to General.

Tap Accessibility.

Scroll down to Home Button, located just above the main accessibility toggle.

At the bottom, toggle on Rest Finger to Open. Now, unlock by resting your finger—no press needed (Touch ID devices only).

You can always return here to disable it and revert to iOS 10's default press requirement.
Ready to go. Explore more Home button tweaks below.
Within Home Button settings, adjust click speed for double- or triple-click sensitivity. Double-click launches multitasking; triple-click opens accessibility shortcuts. Options include Default, Slow, or Slowest—no faster settings.
For a full Home button alternative, especially if hardware issues arise, enable AssistiveTouch. It's a powerful accessibility tool.


From Accessibility, tap AssistiveTouch and turn it on. A floating button appears in the screen corner.


Tap it for shortcuts to Notification Center, Control Center, Siri, Device controls, Home, and more. 'Home' mimics the physical button; Device offers volume, mute, rotation, and gestures.
Tip: Customize the menu for up to eight icons from any submenu for your ideal shortcuts.
