33 steps
  1. Switching off your device

  2. Remove back cover

    Galaxy S9 - Remove back cover 05

    To loosen the back cover, use a heat gun or an ordinary hair dryer. Warm glue is easier to loosen, allowing you to remove the back cover. The easiest way to loosen the back cover is to use a flat and flexible tool such as the iPlastix or iFlex.

    You will also need several picks to unstick the back cover all around.

    1. Heat the spot where you start and place a suction cup on the bottom of the back cover.
    2. Press a flat tool between the back cover and the frame and pull on the suction cup.

    The iPlastix is made of plastic, so it won't scratch the device. On the other hand, it's very soft and tricky to insert.

    Be extra careful, the back cover can break very easily. If necessary, apply the heat several times and try again. Removing the back cover might take half an hour. Take a little more time and work carefully to make sure you don't break anything.

    1. Once the tool is inserted, stick a pick into the gap to keep it open. Then run the tool around the entire edge to gradually loosen the glue.
    2. Then heat the next part and insert the picks one by one.

    The back cover glue is extra strong on the lower edge.

    1. Once the back cover is loosened, lift it very slightly. The fingerprint sensor underneath the camera is still connected with a cable.
  3. Disconnect fingerprint sensor

    Galaxy S9 - Disconnect fingerprint sensor 01

    Then remove all the equally long Phillips screws from the logic board cover and store them together.

    This phone has only two different screw lengths. If some screws don't come off immediately, you can also use a pair of tweezers.

    1. The logic board cover with the NFC tag is latched in at the top.
    2. Pry it up a little and then take it out.
  5. Disconnect battery

    There's a small plastic pin in the opening of the SIM tray. Make sure it doesn't fall out.
