How to detect faults in the sensors of your Android mobile

  • Mobile sensors are essential for everyday functions such as orientation and proximity.
  • Applications such as Multi-Tool Sensors allow you to analyze the status of sensors.
  • Calibrating sensors can be an effective solution to correct common faults.
  • Updating the software or restarting the device may resolve temporary issues.

Detecting faults in Android mobile sensors

Does your phone seem to not work as it should in certain applications or during calls? It is possible that some of your sensors are failing and you haven't even noticed. sensors They are essential components in a smartphone, responsible for functions such as detecting the orientation of the device, measure the ambient light or movementWithout them, many of the features we use daily would stop working properly.

If you think your Android phone might have a sensor problem, you've come to the right place. In this article, you'll find out how to fix it. identify possible sensor failures, what tools are useful to diagnose them and how you can try fix them. Everything explained clearly and in detail so that you can do it yourself without having to resort to technical service, at least not at first.

What sensors does your Android phone have and why are they important?

The smartphones Current models are equipped with a wide variety of sensors that allow specific tasks to be performed. From the most common ones such as accelerometer and gyroscope even the lesser known ones like the barometer, they all play a crucial role. Here is a list of the most common sensors and their most notable functions:

  • Accelerometer: It detects linear acceleration and is used, for example, in racing games to control vehicle movements.
  • Proximity sensor: Turns off the screen when you bring the phone to your ear during a call, avoiding accidental touches.
  • Gyroscope: Measures the angular orientation of the device, essential in augmented reality applications.
  • Ambient light sensor: Adjusts the screen brightness according to the ambient lighting, improving the visual experience.
  • Barometer: Measures atmospheric pressure, useful in weather forecast applications or outdoor activities such as hiking.

In total, a mobile phone can include around 14 sensors, although not all of them are present in all models. Regardless, if one of them fails, you may notice problems such as difficulty rotating the screen, errors in games or problems unlocking the phone with the fingerprint.

Signs that indicate possible failures in your sensors

Recognize if a sensor is failing may not be so obvious at first. However, some common problems could be a warning sign:

  • Your mobile does not correctly detect the orientation horizontal or vertical.
  • Games don't respond as they should, especially those that rely on movement.
  • The automatic brightness of the screen does not adjust properly.
  • Proximity sensor does not turn off screen during calls.
  • Problems with the fingerprint reader, such as not recognizing fingerprints or doing so inconsistently.

If you detect any of these problems, it may be time to evaluate the status of the sensors of your device.

Quick fixes for faulty sensors

Once the problem has been detected, the next step is to try to solve it. Depending on the sensor in question, you can resort to the following options:

1. Sensor calibration

In some cases, sensors They simply need recalibration to resume normal operation. Here are some useful tools for different sensors:

  • Reset proximity sensor: This application focuses exclusively on calibrating the sensor of proximity.
