  • The body is cleaned from glue residues.
  • The touch screen is being prepared: the film is removed, double-sided tape is glued around the perimeter or glue is spread.
  • The touchscreen is pressed against the matrix, the excess glue is removed with a napkin.
  • After the glue dries, the components of the phone are assembled and checked for operability.
  • These are the two main methods of replacing the touchscreen on a smartphone on your own. And to avoid damage in the future, a protective glass is glued to the touch panel. Let’s analyze this procedure in more detail.

    How to replace the glass on your smartphone yourself

    From the above it follows that the replacement is carried out by two different methods, depending on the type of connection of the matrix with the touchscreen.

    Replacing the protective glass on a smartphone with your own hands. Smartphone display elements

    Before studying the direct instructions, you should figure out what modern displays used in most smartphones consist of. Their components include:

      Matrix is ​​a panel of liquid crystal or LED type that contains an array of pixels that forms the final image. On the back there is a stainless steel case, and cover the front with thin glass. The design includes a ribbon cable that connects the screen to the board of the mobile device.

    A touchscreen is a panel that is placed on top of the matrix and registers the user’s touches. The software combines the received information with the arrangement of elements on the screen and performs the appropriate action. When falling, it often takes a hit on itself, as a result of which it cracks. Replacing this element is cheaper than matrices.

    These components can be attached to each other in two ways:

      Through the air gap. This is a simpler design used earlier, which means easy glass replacement without the use of special tools.

    Without an air gap. the so-called OGS-display, which is a single whole, combining the matrix and the touchscreen. Replacement can be done by yourself, but Takes more time and requires the use of special tools.

  • The most important thing when performing the procedure is not to damage the main glass of the phone.

    How to change the main glass of a smartphone?

    Touch screens have seriously expanded the functionality of mobile devices, but since the beginning of their use, technology had to be treated more carefully. Almost any fall from a height exceeding 1 m can damage the main glass of the phone or even the matrix. Tempered glass is used to protect the screen, and the phone itself is often worn in a case.

    In the current article, we will figure out whether it is possible to replace the glass on a smartphone and how to do it depending on the design of the display. We will also consider the process of removing and gluing the protective glass, which will save you from the occurrence of more serious problems.

    OGS replacement

    The separation of the two constituent components in this case is a very complex process, which is carried out only in service centers, and this is not all. If you decide to change it yourself, then it is better to purchase the complete OGS module (along with the matrix).

    The service centers use the following set of tools:

    • stand for screen warming up with preliminary fixation;
    • thread for separating display elements;
    • stencil. after placing in it, photopolymer glue is applied to the phone;
    • UV lamp for bonding.

    It is quite difficult to carry out the operation of separating the elements and gluing them without the specified equipment. Currently, this type of screen is used in most smartphones.

    In general, the replacement of the touchscreen on the OGS-display is carried out in the following sequence:

      Removing the SIM card and memory card, removing the back cover. If the cover is Non-removable, then it is necessary to pick up the case near the screen with a plastic object. You can try to find a detailed disassembly of a specific model on YouTube or other hosting.

    Removing the display module. The procedure involves warming up the device with a hair dryer and pulling the part.

  • The next step, how to change the glass on a smartphone with your own hands, is to prepare the module for disassembly. It is placed on a perforated sheet metal and bolted down. Important not to allow further displacement.
  • The detachment of the matrix from the touchscreen is carried out at a temperature of 80 degrees. The surface gradually warms up, at the end a nylon thread is wound up and separation is carried out.
  • The matrix is ​​cleaned of adhesive residues with a cleaner, then degreased.

    The matrix is ​​covered with a layer of glue and matched with a touchscreen. It is important to match as accurately as possible, otherwise the sensor may not work properly if skewed.

    Dry the glue with a UV lamp. Process Takes 10-30 minutes for the adhesive to cure.

  • Reinstall the module, connect the loop.
  • Assemble the body of the smartphone, check the functionality of the touch screen.
  • This completes the procedure. In the case of replacing an integral module, it is enough only to disconnect the element and the wires suitable for it, then install the new one in the old place and connect it.

    How to glue glass on a smartphone

    Before starting the operation, make sure that in addition to glass, all auxiliary tools are present:

    • lint-free napkin;
    • rubber gloves (optional if you handle it carefully)

    Usually complete with protective glass there is a damp cloth soaked in cleaner, and a second one for wiping dry.

    Bonding is done as follows:

      The smartphone screen is wiped with a cleaning cloth. It is important to go through all the corners so that there are NO specks, stains, fingerprints on the surface.

    The first protective film is removed from the glass. on the side that is glued to the phone.

    The glass is pushed up to the screen and aligned with all the holes, and then lowered for gluing.

  • Protective glass, unlike film, does not leave bubbles, but even if they have formed, it will be enough to run a dry cloth over the surface towards the edge.
  • The procedure is completed, now the touchscreen is protected from external influences. In the event of a fall, the glass will take impact, which is easy to replace.

    Following the recommendations presented, you will be able to independently change the main glass of the phone. The replacement procedure depends on the screen design. If there is an air gap, fewer tools will be needed, if not, more. To prevent damage to the touch panel, a protective glass is used in the future, self-adhesive of which will NOT take much time.

  • As soon as you return home, the smartphone will need to be disassembled and the places where the liquid got into with ethyl alcohol.
  • Wipe the contacts of the smartphone with ethyl alcohol

    This is necessary so that in the future the metal parts of the microcircuits on the board do not oxidize. Since oxidation will destroy important parts of microcircuits. The phone may NOT turn on at all. Thus, we figured out what to do if your phone has a black screen, but the phone itself continues to work.

    To restore normal functionality of your phone’s sensor, do the following:

    • Reboot your gadget. This often helps to effectively fix a phone sensor problem;
    • Wipe the screen of the gadget with a soft, clean cloth (microfiber) moistened with an appropriate liquid for cleaning displays;

    Wipe the phone screen with a soft cloth

  • Remove the protective case from the phone (if available) to make sure that it does not interfere with the correct operation of the sensor;
  • If the sensor is partially interrogated, test the device screen using the phone’s built-in diagnostic tool. Dial the combination on the phone:
  • #. for most Android phones, especially Samsung;

    ###. for most HTC phones;

    ###. for most Sony Xperia phones;

    #. for most Motorola phones.

    In the menu that appears, select, for example, “TSP Dot Mode”, and by pressing in different areas of the screen, VIEW which parts of the sensor are not polled, this can help fix the problem in which the touchscreen does not work.

    • If the device is overheated, move it to a cool place. and let it cool;
    • Tapping gently several times on each corner of the screen has proven to be effective for many users;
    • If your protective film is not glued correctly (air bubbles, dirt, etc. are visible under it), replace the protective film (Contact a specialist for its correct installation on the phone);

    Replace your phone’s screen protector if necessary

  • Temporarily remove the SD and SIM cards (memory card and phone card) from the gadget, in order to make sure that they are NOT a prerequisite for problems with the phone;
  • If the display shows small (or more) cracks, most likely, you will need a complete replacement of your sensor at a service center;
  • In case of significant damage to the device’s screen, only its complete replacement will help.

  • If your touchscreen is dislodged or peeled off, Contact a service center to fix this defect. Otherwise, you can use a regular hair dryer to style your hair, with which you need to soften the glue on which the screen is attached to the phone case, and then reinstall the screen (Perform this operation only if you have sufficient qualifications). This must be done if the sensor on your device does not work;
  • Boot your phone in safe mode. to ensure that one of the commonly run applications is NOT a prerequisite for the problems in question. If the phone started to function normally, you should uninstall recently installed updates one by one in order to identify the culprit of the problem.
  • We restore the operation of the sensor through safe mode

    To boot into safe mode completely Turn off the phone (including by removing the battery). Then perform a long press on the Power button to turn on the gadget. When the logo of Samsung, Nexus, LG, etc. appears on the screen, press the power button, and then hold down the “Volume down” (Volume Down). Press this button when your device boots up, and you will see the inscription “Safe mode” at the bottom left of the screen.

      Calibrate your device. if the sensor has not recovered. To do this, you can use the appropriate applications, for example, “Touchscreen Calibration”;

  • If you install Incorrect firmware, install the “native” firmware of this phone;
  • The radical way is to reset your phone to factory settings in Recovery Mode. Please note that all your information on the phone (including the phone book) will be lost due to such an operation. Enter “Recovery Mode”, select “WIPe data / factory reset””, and then select “Reboot system now” to reboot the device in normal mode.
  • Select “WIPe data / factory reset” to reset your phone to factory defaults

    • The protective film on the screen of the device does not fit snugly enough to the screen (air bubbles between the screen and the film, dirt, etc. are visible);
    • The device has overheated due to various reasons, or has undergone a sharp temperature drop;
    • Moisture got inside the phone, which led to oxidation of the contacts;
    • The sensor is physically damaged due to impact;
    • The sensor is dislodged or peeled off;
    • SD card or SIM card is unstable;
