    1. Insert the spudger into the gap next to the headphones. There are 16 clips on the outside under the back cover. You have to disconnect them by moving the spudger around the entire smartphone one time. Alternatively, you can detach the back cover using your fingernails.
    2. Then you can take off the back cover.
  2. Removing the battery

    1. If your Samsung Galaxy’s still on, turn it off by holding down the standby button for about three seconds and following the prompt on the display.
    2. Now use the spudger or your fingertip to lift the battery (see figure 1) and then remove it (see figure 2).
  3. Removing the SIM card

    2. Now you can pull it out with your fingers.
    3. Repeat this process if you’ve installed a microSD card.

    2. Lift the cover and the chrome frame to remove them. The cover is attached to the display at 14 points. Insert the spudger between the chrome frame and the display. Start at the level of the Home button (see figure 2) and move the spudger once around the entire phone to detach all connections (see figures 3 and 4). Then you can remove the midframe.

    1. First disconnect the following cables. Place the flat end of the spudger very slightly below the contact and lift it up (see figures 1 to 3).
      Touch button cable
      Antenna cable
    2. Now remove the bracket over the USB port by inserting the pointed tip of the spudger between the USB port and the bracket and lifting the bracket with some force (see figure 4). Put the bracket in a compartment of your organizer tray.
    3. Insert the spudger below the USB connector cable and carefully detach it from the base (see figure 5). It’s lightly glued in place.
    4. Now carefully remove it by hand.
    5. In some cases, you may have to remove the adhesive film below it.

    2. If the cable set is fitted correctly, you can clamp the bracket over the USB port again (see figure 2).
    3. Connect the blue antenna cable and then put it back in the cable guide. Be very careful because the contacts could bend if they’re not connected right (see figure 3).
    4. Install the touch button cable again (see figure 3).
