How to Fix Light Sensor Issues on Android

The mobile screen is the main element, without it we can not do any other function and that is why when the automatic brightness does not work correctly due to errors with the light sensor we are faced with a complicated solution. This problem can be very complex to solve or too easy, since we do not have at our disposal any option in Android that allows us to directly reset it quickly.

Fix Light Sensor Issues on Android

Most of the users have happened to us on some occasion, the brightness of our mobile does what it wanted , going down or up when it did not correspond. This small sensor that is usually located on the top of mobile screens is not perfect and makes mistakes that in some cases are related to our use and in others to a fault that we can do little about.

Check for updates

In countless Samsung, Xiaomi, Huawei or any other brand mobiles we have encountered problems related to the light sensor due to a software failure . This has a simple solution through an update, so the first thing we have to do is go to our phone to Settings> System> Update. These steps may vary depending on our mobile, being the solution to our problem.

Just by restarting your mobile you can solve it

When we update the mobile it will restart automatically, but in case of not doing it it is a recommendation that we must take into account. Due to a specific failure, the light sensor may have generated an error that causes the automatic brightness of our mobile to not work well. We can restart it with the traditional method or force the restart by keeping the power button pressed for at least 10 seconds.

Adapt brightness level and other settings

When we say that we must adapt the brightness, we do not mean from the notification curtain, but from the adjustments. It is important to know that the brightness level that we select in the settings allows us to control it manually in general, which will then be adapted through the light sensor, unlike the shortcuts bar where we make a point correction. That is why we recommend from the settings to leave the screen brightness at 50% , later the sensor will do its job.

Other aspects to take into account is the screen calibration, where you must choose a standard color tone that works for us in all kinds of situations and not do it in full sunlight or in total darkness. Also remember that the night mode can produce the feeling that your screen has less brightness, something that we solve by turning it off, changing the color temperature or changing the programming at other times.

Check the light sensor of your mobile

It is likely that the problem is really the light sensor and to find out we must check it manually . In the application store we download the Multi-Tool Sensors application, with which we can check all the sensors on our smartphone.

Once we enter the application we have at the top left the menu to access all the tests for sensors, where in our case we will touch on light. As soon as the new tab is opened, a sensor analysis will begin, showing us at all times the lighting in lux , the unit of measurement that is responsible for measuring the amount of light. We can see through the graph the variation when covering or uncovering the sensor of our mobile and thus find out if it works correctly or fails.

Try another case or screen protector

Given the position of the light sensor in mobiles, it is likely that the case or even the screen protector is affecting its performance. By removing the case we will be able to check if we continue to suffer failures, as with the screen protector, to which we will have to find a substitute to check if the failure continues to recur.

Make a Hard Reset and use the warranty

At this point, we can not do much more to solve the problems with the light sensor and restore normality to the automatic brightness of the screen, we can only rely on the Hard Reset. The process may vary on some mobiles but the first thing we must do at all times is save the photos and files on our mobile phone that we do not want to lose elsewhere .

Hard Reset

  • We turn off the mobile first.
  • Then we hold down the volume up and power buttons at once until the brand or Android logo appears.
  • Next we will move through the menus with the volume up and down keys , accepting with the power button.
  • We will have to follow these steps: ” Wipe data / Factory reset ” “Yes” “Reboot system now”.
  • They could vary according to the mobile and model.

Once we have done this we can reconfigure the mobile and check if the fault has been solved. In case it is not solved, we will be able to check if we have a guarantee on our mobile and use it to solve the problem.
