The Smart screen and Smart video features
The Smart screen and Smart video features keep the phone from activating
screen timeout when it detects your eyes looking at the screen. When you
turn these features on, you can set a shorter screen timeout setting to
conserve your battery power, but still allow you to view a screen for a
longer period of time without having to touch it to keep it activated.
To turn these features on, from the Home screen, tap the Menu Key >
Settings > Display > checkmark the Smart screen checkbox and/or the
Smart video checkbox.
NOTE The following situations may prevent these features from functioning properly:
•
When the phone is in the dark or against bright light.
•
When the front camera lens can't detect the location of your eyes.
•
When the front camera is used at the same time with other apps.
