How does proximity sensor work in Galaxy S21?

As a natural response of the proximity sensor, the display shuts off when the device is held close to the ear during a phone conversation. When something blocks the proximity sensor, the touchscreen locks (screen shuts off) and unlocks immediately when the obstruction is removed. This eliminates unintentional phone interactions and conserves battery life.

Verify that your device’s software and associated apps are updated to the most recent version before attempting the suggestions below. To update the software on your mobile device, take these steps:

  1. Navigate to Settings > Software update.
  2. Tap Download and install in Step 2.
  3. Follow the directions displayed on-screen.

Location And Operation Of The Proximity Sensor

A proximity sensor is composed of a light-emitting component and a light-receiving component. Infrared rays from the light-emitting component measure the distance between the object and the gadget by analyzing the light reflected off physical objects.

Although each model is unique, the proximity sensor is often situated near the top of the screen’s front bezel. As a result of the Galaxy S21 series’ Infinity Display, which minimizes the bezel, the proximity sensor is positioned internally on the top portion of the display.

In models with proximity sensors positioned internally on the rear of the display, the proximity sensor may be engaged and emit a dimly visible blinking light at the top of the screen. Please note that this is not an issue with the display or performance.

Why Is Proximity Sensor Not Working In Galaxy Phone?

After the Galaxy S5 series, proximity sensors cannot be turned on or off. If the proximity sensor is malfunctioning, verify the following.

Check 2: Wipe The Sensor With A Soft Cloth

The proximity sensor is often situated on the top of the phone, however model-specific details may differ. Utilize a soft, clean towel to wipe the device’s front.

Note: The proximity sensor may not function properly as a result of  hair or accessories such as screen protectors generating static electricity.

The proximity sensor will be off when using speakerphone or Bluetooth headphones. The lock screen (Display Off) function will be disabled, allowing you to use the screen during the call. The proximity sensor will function for calls that are not made via Bluetooth or loudspeaker.
