Waking your smartphone If the screen is off and the smartphone does not react to any taps on the screen or front panel button, then it has been locked and is in sleep mode. Press the power button to wake your smartphone. Unlock your smartphone by sliding your finger from one side of the screen to the other (it works both ways). For additional security, you may set an unlock pattern, a set of dots that must be touched in the correct order to access the phone.
