The proximity sensor detects when a user is holding the phone near their face during a call and turns off the display to prevent keypad presses and battery consumption from the display. The proximity/light sensor is located to the right of the earpiece.
Why does my phone have a proximity sensor?
In Android, the proximity sensor is primarily used to detect when the user’s face is close to the screen. This is how the phone screen seems to know to switch off when you hold it up to your ear during phone calls, preventing any errant button presses.
What happens if I disable proximity sensor?
Android phones equipped with a proximity sensor disable the screen when you hold the phone close to your face while you are on a call. The point is to save power — since you cannot use the phone’s touchscreen for checking Facebook when you are pretending to pay attention to your phone call.
What is use of proximity sensor in mobile?
Proximity Sensor
Detects when an object is near to the phone. Most commonly used to sense when a phone is held up to the users ear to turn off the display. This saves both battery life and prevents accidental screen touches.
How do I check the proximity sensor on my phone?

Which type of proximity sensor is used in mobile?
Comprised of an infrared LED and an IR light detector, a proximity sensor detects how close the phone is to an outside object, such as your ear. This sensing is done to reduce display power consumption while you’re on a call by turning off the LCD backlight.
What is the working principle of proximity sensor?
Inductive Proximity Sensors detect magnetic loss due to eddy currents that are generated on a conductive surface by an external magnetic field. An AC magnetic field is generated on the detection coil, and changes in the impedance due to eddy currents generated on a metallic object are detected.
Which type of proximity sensor is used in mobile phones?
mobile phones use IR-based proximity sensors to detect the presence of a human ear. This sensing is done for two purposes: Reduce display power consumption by turning off the LCD backlight and to disable the touch screen to avoid inadvertent touches by the cheek.
