You can wake up your phone by turning on the display
and unlocking the keys.
1. Press the Power key to turn the screen on.
2. Swipe up on the screen.
NOTE:
If you have set a face verification, a fingerprint, an unlock
pattern, a PIN or a password for your phone, you'll need
to use your face or fingerprint, draw the pattern, or enter
the PIN/password to unlock your screen.
