Your Galaxy S10 has suffered water damage?

In this manual we will show you how to remove the mainboard of your Samsung S10 to dry it on your own.

Since the fragile, firmly adhered glass back cover must be removed first to remove the mainboard, we have classified this repair as difficult.

    1. Keep the Power button pressed until the option "Switch off" is shown on the display.
    2. Confirm the "Switch off" with your finger and wait until the screen is black.
  2. Heating up the back cover

    Heat gun

    The back cover is firmly glued. To loosen it, you have to heat it up first.

    1. First turn your Galaxy S10 with the display side down.

    To avoid scratches on the display screen, you should place your device on a clean, soft surface.

    1. Use a hot air device, such as a heat gun or a regular hairdryer, and drive it evenly over the edge of the back cover from the outside.

    As a rule of thumb, heat the edge of the back cover only to the point where you can still touch it without burning your fingers.

    Used tools
  3. Creating a gap

    Once opened, your Galaxy S10 is no longer waterproof, and the warranty for protection against dust and splashing water expires.The backcover is made of glass and can break very easily. Therefore, be extra careful and take your time.

    1. Place a suction cup at the bottom of the backcover and pull it upwards to create a narrow gap between the backcover and the housing frame.
    2. Insert a flat, sturdy tool into the created gap. Try to enlarge the gap by pushing the backcover with the tool additionally upwards. We use the iFlex for this.

    Used tools

    Take care not to insert your tool too far, so that you do not damage anything under the backcover.

    1. Use a flat plastic tool to go around the edge of the housing piece by piece. We use the iPlastix for this.

    The iFlex is made of thin, sturdy metal, making it easier to get into the gap between the back cover and the case frame. However, the sharp edges of the iFlex make it easier to scratch the frame. We therefore recommend that you use the iFlex only initially and continue with iPlastix, which is made of flexible plastic, as soon as possible.

    1. To prevent the adhesive from rebonding in the areas that have already been loosened, you should always heat the edge of the display and leave individual, flat picks in the device frame.
    2. Remove the detached back cover and put it aside.

  5. Removing the plastic cover

    • 8 × 3,9 mm Phillips

    Under the back cover there is a plastic cover which is connected to the coil for contactless charging and the NFC antenna.The cover is hooked onto the upper edge of the display unit, the coil is slightly glued.

    1. First unscrew the Phillips screws that hold the plastic cover in place.
    2. Slide a flat tool under the glued coil to carefully loosen it. We use a steel spatula for this purpose.
    3. Then lever the plastic cover with a lever tool from the upper edge of the display unit. For this purpose we use a plastic spudger.
    4. Now you can remove the cover including the coil and the NFC antenna.
