The Sensor Does Not Work On The Iphone, Diagnosis, Repair

Apple monitors the quality of the parts from which its devices are assembled. Almost every element is being finalized in the new generation of devices, but no one is safe from marriage or the occurrence of problems during operation. One of the most common malfunctions for iPhone and iPad is a sensor failure. The touchscreen may fail fully or partially, without responding to user touch across the entire surface of the screen or only in a certain area. If the sensor does not work on the iPhone or iPad, you should not immediately take the devices to a service center, often you can solve the problem yourself.

Signs of a faulty sensor in iPhone

In the iPhone and iPad, the display module consists of three components: a protective glass, a display and a sensor (touchscreen). Sensor malfunctions are manifested by the following symptoms:

  • Touching elements on the screen does not lead to actions;
  • Actions on the screen occur with a delay, some time after touching;
  • Touch is not processed over the entire surface of the screen;
  • Actions on the screen occur without touching it: the smartphone launches the application itself, various menu items are pressed, and so on;
  • Touch is not processed correctly, that is, the action does not take place in the area of ​​the screen where the touch was made.

The symptoms described above may be present constantly or appear for a while, after which the iPhone will start working normally again.

It is impossible to use a touch device with a faulty touchscreen, and it is necessary to fix the problem immediately after it occurs. However, it is not always caused by improper operation of the sensor; in some cases, errors in touch processing occur at the software level.

What to do if the sensor on iPhone works poorly

If the problem with touch processing is caused by a software failure, then the user of the device can fix it independently, without the help of specialists. For this, it is necessary to perform a “hard reset” of the device, holding both the “Home” and “Turning the device off / on” buttons. After 15-20 seconds, the smartphone’s screen will turn off, after which the Apple icon will light up on it – this means that the reboot was successful. After the iPhone boots up, you can test it for the quality of the sensor.

IPhone Sensor Calibration

Apple does not allow users to calibrate the iPhone or iPad sensor. There are no tools in the device settings that would be responsible for calibration, and only service center specialists can perform it, as stated in the official documentation for Apple smartphones and tablets.

At the same time, some touchscreen settings are provided in the iPhone, but they concern only models older than the iPhone 6S and iPhone 6S Plus. It’s about adjusting the sensitivity of the 3D Touch function. To adjust the pressing force to perform various actions when using 3D Touch, you must do the following:

  1. Go to "Settings";
  2. Select the menu item "General";
  3. Go to the tab "Universal Access";
  4. Click on the “3D Touch” option, after which it will be possible to adjust the sensitivity of the screen.
