Waking up to the lock screen

Go from sleep mode to the lock screen without reaching for the POWER button.

Important: If you've set up a screen lock with credentials, you'll be asked to provide your credentials first before HTC One M9‍(‍s‍) unlocks.

1. Lift the phone in portrait orientation.
2. Immediately double-tap the screen.

Make sure you're not touching the screen when the phone vibrates.
