The backcover fell down and cracked.

With these instructions you will have replaced the back glass of your Samsung Galaxy S20 independently and inexpensively in no time.

The repair is relatively simple, since the old back cover only needs to be removed and the new one attached. Usually, when removing a backcover, the difficulty lies in not damaging the glass. Here you don't have to pay too much attention, because the backcover is already broken.

If you still have questions or encounter obstacles, you can always contact our support. We are always happy to help!

    Opening your smartphone can be a very delicate operation, especially if the glue is very persistent. The blade of the flexible but sturdy iFlex measures just 0.15 mm, so it fits in even the smallest gaps, such as between the screen and the frame. The practical iFlex is made of stainless steel and sits comfortably in the hand. This makes it the perfect assistant for every smartphone repair.

    The glass back cover of the Samsung Galaxy S20 is strongly glued.

    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.

    If your back cover is severely broken and the suction cup does'nt hold properly, you can stick some tape on the back glass.

    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.

    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 frane from time to time and work carefully. This step may take some time.
    1. In the area of the camera you should also take care not to insert your tool too far into the device.
    2. When the back cover is loosened, you should compare your old one with your new one. It could be that you have to take over the covers for the cameras or the microphone. Loosen these components with hot air and insert them into the new backcover.
    3. On an original backcover from the iDoc-Store the cover and microphone are already installed.

  4. Attaching the back cover

    1. If necessary, remove the old adhesive residue from the frame of the device so that your new backcover can lie flat and flush.
    2. Remove all protective films over the adhesive surfaces of your new back cover.
    3. Position the backcover over the device and put it down slowly.
    4. Heat the backcover again with hot air so that the adhesive bonds again.
    5. As long as the glue cools down, you can press the backcover down with your fingers or weight it down with a few books.
    Please note, that after opening the device for the first time a 100% protection against the ingress of dust and liquids can no longer be guaranteed.
