How to Fix Android Phone's Proximity Sensor not Working

Smartphones are made up of several components that come together to provide us with the convenient experience we’ve come to expect. Many of the ways we use our phones are made easier by the proximity sensor, and you won’t realize how much until it stops working.

Let’s examine what a proximity sensor in a mobile phone is and how to repair one that has malfunctioned.

What Does a Proximity Sensor Do?

One of the several smartphone sensors is a proximity sensor. Its job is to sense how near you are to your phone and adjust its response. As a result, functions can be activated in reaction, such as lighting up your screen when you gaze at it or shutting off the display when you hold your phone up to your ear.

Your mobile phone’s proximity sensor recognizes your facial characteristics to unlock it. The sensor will stop accidental touches if your phone is in your pocket. It’s a helpful chip that could go unnoticed in everyday life but greatly contributes to tiny conveniences.

How to diagnose and fix your Proximity Sensor

There are tests you can do to see whether your phone’s proximity sensor is functioning correctly if you are uncertain. Before doing any of the following, we suggest restarting your phone to get rid of any transient issues or malfunctions that could be impacting it.

Lifting your phone to your face and watching to see whether the sensor lights up is one method to test it. Another method is to put your phone near your ear while on a call and check if that dims the screen. 

If none of these work, you can test the proximity sensors by downloading a free app, such as Sensor Test.

The Samsung Members app can be used to diagnose your Samsung phone and check to see whether the sensor is operating appropriately. If none of these techniques succeeds, your proximity sensor probably isn’t functioning correctly, therefore you should attempt one of the below-listed fixes.

1. Remove Dust and Dirt Close to the Sensor

Although dust and grime may not seem like major issues, once they start to accumulate, they can harm your phone. Dust might hinder your proximity sensor from correctly recognizing your face if it is obstructing it.

Gently wash the top of your phone where your sensor is positioned using a clean cloth or ear swab. Refer to the image above if you’re unclear about its location. The proximity sensor is always found near the top of your phone, regardless of the model.

Test it after cleaning to check whether it now works. Also, check for any nearby fractures or scratches that can compromise your sensor. You may need to go to a repair facility if they are there.

2. Check if the Screen Guard Is Blocking It

Another major factor in the proximity sensor’s malfunction is screen protectors. The glass can interfere with detection if it is either too thick or not designed for your phone. If you’ve just installed a new screen protector, gently remove this object from your touchscreen before cleaning your screen.

Use the steps listed above to determine whether the phone’s sensor is now operational. When purchasing screen attachments, be careful to choose one made expressly for the model of your phone and test it to ensure proper operation.

3. Use an app to calibrate the proximity sensor on your device

Recalibrating your phone’s sensors might assist in resolving issues that may have arisen as a consequence of faults or errors. Calibration is crucial since it makes sure your sensors are appropriately gathering data.

You may have seen it while using Google Maps, which periodically asks you to calibrate your compass so that it can always precisely estimate your location.

Recalibrating your sensors helps ensure correct operation, much as when you reset your phone. Use the Proximity Sensor Reset/Fix app, available for free from the Play Store, to calibrate your proximity sensor.

4. Update Your Smartphone

Your phone can sometimes experience bugs or other problems. This can be the result of incompatible software upgrades or it might simply be a case of short-term problems that go away on their own. To address these vulnerabilities, phone makers offer updates, so it’s a good idea to make sure your phone is updated.

Go to Settings > System > Advanced > System Update to see whether your phone needs any upgrades. You can locate it under Settings > Software update > Download and install on Samsung mobile devices.

5. Reset Your phone 

If everything else fails, it’s likely that your phone is broken and has to be sent to a repair shop. Because of this, it might be wise to try resetting your phone first. By doing this, all data will be removed, leaving a blank slate in its place. This can eliminate any bugs that other approaches might not have been able to get rid of.

Before doing so, it is advisable to create a data backup and sync all of your files to your Google account. By doing it this way, you won’t lose any data, and after the reset is complete, Google will restore everything for you. Samsung mobile devices include built-in backup programs.

6. Visit a professional

Your proximity sensor probably has to be brought to a repair facility if none of the aforementioned fixes can make it work again. This is the most apparent reason if you just dropped your phone or got into any mishaps with it. Due to its fragility, the proximity sensor is readily harmed by excessive pressure.

We advise bringing your smartphone to an authorized repair facility and letting the experts handle it. The smartphone is fragile equipment that you should not attempt to repair without any expertise, even if it could be tempting to follow a YouTube video and try to fix it yourself.

Without a proximity sensor, your phone could still function

Smartphones are being improved to make our life simpler. Although theoretically possible, using a phone without a proximity sensor can even be rather simple if you get accustomed to it.

Nevertheless, the convenience it provides should not be taken for granted. Your total phone experience is significantly influenced by the value these minor parts bring.
