Your device is equipped with a sensor to detect user presence based on movement of heat sources. When the Presence Sensor detects someone, your device wakes up from sleep mode and starts projecting.
The Presence Sensor starts to work when you are using wall projection mode, 10 seconds after your device goes to sleep. You can also set the Presence sensor manually for table projection mode. The Presence Sensor has a detection range of 110° for up to two meters.
The Presence Sensor may detect not only a person, but also a pet or heating appliance. It may not work properly when the ambient temperature changes due to air conditioning or if the user is in front of the device, but does not move.
To change the Presence Sensor settings
- Find and tap Settings > Display.
- Tap Presence sensor settings, then select an option.
