• iPhone se changed the screen, the sensor does not work well. Why does the iPhone slow down and how can you speed it up?

    Apple monitors the quality of the parts from which its devices are assembled. Almost every element is improved in the new generation of devices, but no one is immune from defects or problems arising during operation. One of the most common problems with iPhone and iPad is sensor failure. The touchscreen may fail completely or partially, not responding to user touches across the entire surface of the screen or only in a certain area. If the sensor on your iPhone or iPad does not work, you should not immediately take the device to a service center; you can often solve the problem yourself.

    Signs of a faulty iPhone sensor

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


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

    enjoy touch device with a faulty touchscreen is impossible, and it is necessary to fix the problem immediately after it occurs. However, it is not always caused malfunction sensor, in some cases errors in touch processing occur at the software level.

    What to do if the sensor on your iPhone is not working properly

    If a problem with touch processing is caused by a software glitch, then the device user can fix it independently, without the help of specialists. To do this, you need to perform a “hard reboot” of the device by holding down the “Home” and “Power off/on the device” buttons simultaneously. After 15-20 seconds, the smartphone screen will go dark, after which it will light up apple icon- this means that the reboot was successful. After the iPhone boots up, you can test it for sensor performance.

    In addition, if the sensor on your iPhone is not working well, you should make sure that the problem is not related to the case (or bumper) of the device. Often spontaneous clicks on the sensor are associated with improperly applied film to the screen. If there are errors in the operation of the touchscreen, it is better to remove all protective accessories and see how the sensor responds to touch without them.

    iPhone sensor calibration

    Apple does not provide calibration capabilities iPhone sensor or iPad users. 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 only apply to models older than the iPhone 6S and iPhone 6S Plus. We are talking about adjusting the sensitivity of the 3D Touch function. To adjust the pressure to perform various actions when using 3D Touch, do the following:


    How to replace the touchscreen on iPhone

    Replacing the sensor on an iPhone or iPad is a complex procedure that requires special skills, tools and a spare part. In most cases attempts self-replacement touchscreen in a smartphone leads to damage to other components of the device, cracks/scratches on the case and other problems. That is why it is better to trust iPhone repairs to specialists from trusted service centers.

    Frequent users modern smartphones Apple people are wondering what to do if the sensor on the iPhone is faulty, for example, after replacing the glass. And all because all the work mobile devices with touch displays is directly related to the high sensitivity of the screen to pressure, with which you can use the functions of the gadget, view menus, and work with documents. If the sensor stops working, even after replacing the display, you lose the opportunity to fully realize your needs, which are often very necessary to fulfill.


    Why does the sensor on a smartphone stop working?

    The touchscreen on an iPhone can start to glitch completely spontaneously, for example, after replacing the display or if the smartphone has been dropped. As a rule, the reasons why a particular phone model does not respond touch screen touch or touchscreen responds intermittently and is associated with mechanical damage to the device. To protect the display from impacts, you can install a protective glass on it or replace the film on it. Without additional protection, for example, if it falls, the touchscreen on the iPhone sometimes begins to freeze or completely fails.

    Also, the reasons why the iPhone screen glitches and the touchscreen stops working are the following:

    • liquid entering the device body
    • crash after replacing software
    • failure to comply with manufacturer's requirements when replacing display glass

    If you are sure that the iPhone has not been dropped or water has been spilled on it, but it does not respond to touches, does not turn on, or does not respond correctly to presses, then most likely there is software failure, which you can eliminate yourself.

    How does a malfunction of the display module manifest itself?

    There are several signs that indicate that the sensor is faulty or the touchscreen on the iPhone is not working. These include the following:

    • lack of sensor response to touches in a certain part of the screen
    • ignoring any clicks on the display, which indicates that the sensor is lagging
    • random operation of the gadget after it has been dropped or after replacing the glass (applications and documents open on their own)
