The proximity sensor is located at the top of your phone and if you hold the screen at a slight angle, you can see the sensors.
No Screen Replacement and Still the Problem
- Restart the Phone.
- Go To “Call Setting“.
- Select “Incoming Call Settings”
- Torn ON the “Proximity Sensor” Option.
- in 99% of the Cases, this will Solve and Fix the Problem.
- But in Case if the Problem is Not Solved then Soft Reset the Phone and Check.
Check if values of proximity sensor change as you move your hand close to the sensor. Check light sensor as well. Whatever the result is, try and remember about any app you installed recently and remove them, and reboot the phone.
It's used to detect when you're holding the phone to your ear so that your cheek doesn't accidentally tap buttons while on a call. If it's not working correctly, it might think that your phone is always next to your face so it leaves the screen off while a call is active.
The proximity/light sensor is located to the right of the earpiece.
- From a home screen, tap Phone (located in the lower left).
- Tap Menu .
- Tap Call settings.
- Tap Turn off screen during calls to enable or disable. (Enabled when a check mark is present.)
You can test the sensor in a dark area and then by moving your phone to an area with bright light. If screen illumination changes, that means light sensor is working. Orientation sensor detects the direction status of your Android device. It checks the screen's auto rotation.
Try turning off "Auto Screen Off During Calls (Turn on proximity sensor during calls)". Click the Phone App > Menu Button > Call Settings. Option 3: Try doing a Battery Pull while the phone is on and wait 30 seconds before putting it back in.
Proximity Sensors Compared: Inductive, Capacitive, Photoelectric, and Ultrasonic. Proximity sensors detect the presence or absence of objects using electromagnetic fields, light, and sound. There are many types, each suited to specific applications and environments.
According with the non contact object detection method,
there are five
types of proximity sensor.
They are,
- Inductive Proximity Sensor.
- Optical Proximity Sensor.
- Capacitive Proximity Sensor.
- Magnetic Proximity Sensor.
- Ultrasonic proximity Sensor.
The proximity sensor is located at the top of your phone and if you hold the screen at a slight angle, you can see the sensors. They look like small holes covered by the screen glass and are close to the speaker.
OPERATING PRINCIPLES FOR INDUCTIVE PROXIMITY SENSORS
Inductive proximity sensors are used for non-contact detection of metallic objects. Their operating principle is based on a coil and oscillator that creates an electromagnetic field in the close surroundings of the sensing surface.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.

Samsung Galaxy S7 Edge:
- Fingerprint Sensor.
- Accelerometer Sensor.
- Gyro Sensor.
- Proximity Sensor.
- Compass Sensor.
- Barometer Sensor.
- Heart rate Sensor.
- SpO Sensor.
Proximity sensor is a sensor able to detect the presence of nearby objects without any physical contact while Proximity switches open or close an electrical circuit when they make contact with or come within a certain distance of an object.
Different Types of Mobile Phone Sensors and their Function
- Accelerometer. The Accelerometer Sensor in a Smartphone (Both Android and Apple iPhone) can detect Tilt or Orientation of the Phone.
- Air Humidity Sensors.
- Ambient Light Sensors.
- Barcode / QR Code Sensors.
- Barometer.
- Fingerprint Sensors.
- GPS.
- Gyroscope.
Depending on the type of proximity sensor, sound, light, infrared radiation (IR), or electromagnetic fields may be utilized by the sensor to detect a target. Proximity sensors are used in phones, recycling plants, self-driving cars, anti-aircraft systems, and assembly lines.
Proximity sensors are suitable for damp conditions and wide temperature range usage, unlike your traditional optical detection. Proximity sensors are also applicable in phones as well, be it your Andriod or IOS devices. It consists of simple IR technology that switches on and off display accordingly to your usage.
The most frequently used different types of sensors are classified based on the quantities such as Electric current or Potential or Magnetic or Radio sensors, Humidity sensor, Fluid velocity or Flow sensors, Pressure sensors, Thermal or Heat or Temperature sensors, Proximity sensors, Optical sensors, Position sensors,
Proximity sensors, ultrasonic or not, sense that an object is within the sensing area at which the sensor is designed to operate. They do not indicate the distance, just that something is there and send a signal indicating such, usually a switch closure or a voltage for on or off, there or not there.
While on the call, hold the phone in your hand. Put your other hand over the top of the phone where speaker is. If the proximity sensor is working, the screen will go dark and come back on when you move your hand away.
Use iPhone stock apple app Voice Memos. Make short recording, play back with loud speaker OFF, and then you can test the Proximity Sensor. You can use Phone diagnostics app developped by Hitek Nova to test most of the functions including proximity sensor:
In Most Android Smartphones, you will Find the “Call Setting” Option by Pressing the Dealer. In some Brands and Models, you may find the Option in Setting. in 99% of the Cases, this will Solve and Fix the Problem. But in Case if the Problem is Not Solved then Soft Reset the Phone and Check.
How to disable a proximity sensor on your Android?
- Turn on your phone, go to "Settings", then "System Apps";
- Scroll down the applications list to "Call settings";
- Tap "Incoming call settings";
- Disable a proximity sensor.
- Test your phone during a call again.
If it seems to be working ok, then it may be that the shattered glass overlying the sensor is making the sensor think something is right in front of it, in which case fixing the glass should be enough. But if you want to be safe, replacing the sensor is probably reasonable. Welcome to Android Central!
Clean your phone and phone case
Carefully clean the front of the phone with a dry, lint-free cloth, noting that the proximity sensor is that little dot just above the speaker on the face of the phone. Clean the case, and consider getting a new screen protector, and then put both of these things back on the phone.There is an “ambient light sensor” at the top of your phone's screen near the selfie camera which can detect light so it knows when the phone is next to your face or in your pockets, this also helps with the auto brightness feature as well (if you get a bright flashlight and shine it at the top of your phone, you could
You can't actually turn off the proximity sensor on an iPhone, so your best option is to make sure it's working properly. Your iPhone's proximity sensor can tell when you're holding the phone up to your ear, and it will shut off the screen, saving battery and preventing your face from accidentally hitting buttons.
