Activate the proximity sensor on Android

Since, as I have already explained in the introduction, the proximity sensor works automatically when you bring the device to your ear when receiving or making a phone call, it is activated by default and there is no need to put your hand in the settings to enable it manually.

However, if you have 'tampered' with your device settings and are concerned that you have mistakenly disabled the sensor in question, know that you can reactivate it by going back to Android settings. Due to the "fragmentation" that characterizes the operating system de Google (that is, the existence of numerous versions of it), there is no "standard" procedure for activate proximity sensor on Android. In general though, you should be able to do this from your phone's settings.

Try the following: Start the application Telephone to access the marker (the screen from which you dial phone numbers), press the tres puntos in the upper right, on the button (≡) or icon rueda (depends on the device you have), tap the item Call Settings / Call Settings and check the box Enable proximity sensor / Turn off screen during calls (if not yet present).

In some devices, the proximity sensor can perform other functions: for example, it can allow you to navigate screens with gestures or it can prevent the device from turning on when it is in your pocket or bag. If these 'additional' features are also available on your device, you should be able to locate them by opening the app configurations (the one with the icon representing the Gear located on the home screen) and going to the section Visual display.

Unfortunately, I cannot go into details because, as I explained above, the available procedures and functions vary from device to device. If you want to try to understand how to activate a "secondary" function of the proximity sensor like the ones I mentioned above, try doing a Google search for terms like " proximity sensor by gestures [nome / modello del tuo device] "or" Proximity sensor screen off in your pocket [device name / modello] «. Through this simple search, you may be able to trace the exact procedure to follow, perhaps thanks to the official support forum of your mobile phone / tablet manufacturer.

Check the status of the proximity sensor

Have you activated the proximity sensor on Android using the procedure I outlined in the previous chapter, but it doesn't seem to work properly? In that case you can check the status of the proximity sensor going to the panel that becomes visible by pressing secret codes or resorting to some applications ad hoc, to find any malfunctions.

Secret codes

To access the hidden menu through which to check the status of the proximity sensor, you can use secret codes, which is a sequence of numbers and symbols that allow access to a whole series of settings that are generally inaccessible. To continue, open the app Telephone, access keyboard pressing the button To compose (the wording may be slightly different depending on the version of Android you are using) and write the code *#*#4636#*#*. If that doesn't work, try the codes * # * # 0 o # 7378423 # * # *.

After successfully accessing the secret menu, select the item Sensor Test / Service Test / Phone Information (depends on the device in your possession) and, on the screen that opens, press the item corresponding to the proximity sensor test (ex. Proximity switch ).

If an error message appears, there is obviously something wrong with the sensor - if it is a software issue, you may be able to resolve it simply by restarting the device or doing the reset (I'll explain how to proceed later). However, if problems persist, the problem could be hardware related, and therefore you should bring the device for assistance at an authorized repair center.

Sensor test

As I told you, there are also some applications that allow you to test the "status" of the sensors on your Android device: one of them is Sensor test. After installing and launching this free application on your terminal, press the button (≡) in the upper left and select the item Closeness from the menu that appears on the left side.

As you can see, the wording appears at the top of the screen. FAR : to check that the sensor is working properly, place a finger on it (near the ear capsule) and, if the text SEARCH, it means that the proximity sensor has detected your hand and is working properly.

If the phrase "NEAR" does not appear when your hand approaches the proximity sensor or if, when opening the side menu, the presence of the latter is not even indicated, there is obviously a problem. If this is software related, you can solve it by simply restarting the device or doing the reset (I'll explain how to do this later). If, on the other hand, it is a hardware problem, you must bring the device for assistance.

Proximity sensor test

Another useful application to check the status of the proximity sensor is Proximity sensor test. This is a free application that allows you to easily check if your device's proximity sensor is working well or not. It works on practically all devices (although the developer has reported problems with the Motorola G5, where it is not fully functional).

After installing and starting the proximity sensor test, press the button Test located at the top and after seeing the red screen, run your palm over the top of the screen (where the proximity sensor should be present) - if the screen turns green, then the sensor is working correctly. If the palm of the hand is not detected and the screen remains red, the sensor is obviously malfunctioning.

If this malfunction comes from software-related issues, you can try to fix it by restarting the device or doing a reboot (which I'll talk about shortly). If, on the other hand, it is a matter of hardware problems, the device must be repaired in a specialized center.

What to do in case of problems

After checking the status of the proximity sensor, you have come to the conclusion that it is not working properly and now you would like to know what to do to solve the problem ? As I've already mentioned in the previous paragraphs, a lot depends on the cause linked to the proximity sensor malfunction - if it's a software issue, you might be able to fix it simply by performing a rebooting the device or making a full reset.

To perform the Reiniciar on your Android device, press the Power button (the one that is on / off), select the item Delete, wait a few seconds and then press again Power button to restart the device. If the device is locked and you cannot reboot using the procedure I just outlined, press and hold the button for about ten seconds Power button : Your device should turn off completely and you should be able to turn it back on.

Otherwise, if pressing only the on / off button cannot force restart the device, try holding the buttons for about ten seconds Power + Volume (-) / (+) o Power button + Home and, if your device has a battery removable, remove it from its compartment and reinsert it after about ten seconds. For more information on how to restart androidPlease refer to the guide I just linked to you.

Did you not solve the problems related to the operation of the proximity sensor by restarting the device? Well then try the device reset going to Settings> Backup & Reset> Factory data reset> Reset phone> Erase everything (if the device is working properly and is not locked) or run the full reset (if you can't reset it using the procedure I outlined above, if it's locked). Both operations allow you to delete all the data present on it in one go and thus instantly solve all the problems related to any software "conflict". However, before proceeding, I invite you to make a backup of your data (as it will be lost).

To perform the full reset on your device, do the following: Press the keys simultaneously Volume (+) + Power + Home o Volume (-) es Power until the device reboots. In the menu that opens (the recovery one), select the item Recovery and choose the option Delete data / factory reset (to go to the recovery menu press the button Volume (-) and to select the different options, press the key Volume (+) ).

Finally, select the item Restart and if everything went well, the initial operating system setup procedure will start. If you need more information on how to reset Android, do not hesitate to consult the guide that I just linked to you.

If after restarting and resetting your device, the proximity sensor continues to throw a tantrum, it is likely that behind its malfunction there is a hardware-related problem: in this case, bring your smartphone / tablet in service to repair it.
