    Used tools

    The Samsung Galaxy S20 is opened via the heavily bonded glass back cover.

    1. Heat the frame of the device with hot air to about 60-80 degrees. Heating it makes the backcover's adhesive easier to remove.
    2. Take a suction cup and place it on the bottom of the device.
    3. Pull the suction cup and guide your flat opening tool into the resulting gap.

    The iFlex opening tool, which is made of thin, strong metal, is very suitable for removing such glued back covers. Once inserted, we recommend using a plastic tool, as this will not scratch the frame and back cover.You can also use an iSclack instead of a suction cup. This tool works like a pair of pliers with suction cups on both sides.

    1. Insert a narrow plectrum into the already loosened part so that the glue does not reattach.
    2. Guide your tool along the entire edge of the back cover.
    Warm up the tool from time to time and work carefully to avoid breaking the glass. This step takes some time.
    1. In the area of the camera you should also take care not to insert your tool too far into the device.
    Please note: Once the device has been opened for the first time, a hundred percent protection against the ingress of dust and liquids can no longer be guaranteed.

  3. Removing the charging coil

    An iDoc magnetic pad can help you sort screws and smaller components.

    1. Before you put the backcover back on you should check the glue. It should be evenly distributed on the edge of the backcover. Remove excess glue if necessary.
    2. If you like, you can also remove the old glue and use a new one.
    Please note, that even with a new adhesive frame a 100% protection against the ingress of dust and liquids can no longer be guaranteed.
    1. Before attaching a new adhesive frame, you must first remove all old adhesive residues on the backcover and frame. You can use a plastic supdger to scrape off some of the glue. Cleaning alcohol and a lint-free cloth can help to remove the residue.
    2. Check the alignment of the frame, then peel off the first protective film and apply the adhesive to the frame. Don't press it down yet, but check that it is properly seated on all sides. The adhesive should not protrude at anywhere.
    3. Press the adhesive down all around so that it bonds properly to the frame.
    4. Loosen the second foil. Make sure that the adhesive does not come off the frame.
    5. Position the backcover over the device and put it down slowly.
    6. Heat the backcover again with hot air so that the adhesive bonds again.
    7. As long as the glue cools down, you can press the backcover down with your fingers or weight it down with a few books.
