Galaxy S8 - Replacing the wireless charging antenna

1. Shut down your Galaxy S8 by pressing the power button until you see the option "Switch off".
2. Now you can confirm the shut down of the mobile phone. Start the next step as soon as the screen stays black.

Now you have to release the back cover of the Galaxy S8. As this is glued, you will need a heat gun or a regular hairdryer. The heat will loosen the glue, so that you can remove the back cover more easily. In addition, you'll need a flat, flexible tool like the iPlastix or iFlex as well as several picks to remove the back cover all around.

1. Heat the back cover all around with a hair dryer to loosen the glue. Do not put the hair dryer too far away, you will need it again and again in between. Place a suction cup on the bottom of the back cover.
2. Pull the suction cup on the key ring upwards and try to press a flat tool like the iPlastix or iFlex between the back glass and the frame at the same time. You can always use the hair dryer to help you do this, so that the heat will loosen the glue at this point.

The iPlastix is made of plastic, which protects the frame from scratches. However, the tool is very soft and therefore difficult to insert.

The backcover is made of glass and will break easily. For this reason, be very careful when removing the back cover. If necessary, use the hair dryer and the flat tool again and again. This step may take you more time than you think - even experts need up to half an hour to remove the back cover. So take some time to complete this step to make sure you don't break anything.

1. Once you have managed to insert the flat tool between the back glass and the frame, you now insert a plectrum into the gap. This way the gap remains open and you can take out your tool again.
2. Repeat this along the entire edge. Pull the tool through the gap to loosen the glue bit by bit.
3. In between you can always reach for a hair dryer. Re-heat the area you are working on. In this way, you will gradually insert the other picks.

On the lower side the backcover is more strongly glued than on the other places.

1. The fingerprint sensor is connected with a cable under the camera. Therefore, lift the back cover very slightly once you have loosened it everywhere.

1. After loosening the back cover and carefully lifting it up, disconnect the fingerprint sensor from the spudger.
2. Now the back cover is completely detached - you can lift it off and put it aside.

• 8 × 3,6 mm Phillips Schraube

1. Remove the screws that attach the upper cover to the display.
2. The cover with the NFC antenna is glued onto the battery. Heat the part with the NFC antenna slightly with a heat gun or hairdryer.
3. Then carefully insert a flat tool under the antenna and remove it. The cover is hooked onto the enclosure.

1. Carefully slide in a steel spatula where the wireless charging coil is glued to the NFC antenna and pry off the contact.
2. Now slowly remove the entire flex cable from the cover.

If the cable is hard to remove, you can use a heat gun to soften the glue.

1. Reattach the NFC antenna. Use the small plastic pins on the cover to position it correctly.
2. Press the flex cable to the back of the cover to glue it on.

• 8 × 3,6 mm Phillips Schraube

1. Put the cover with the antenna back in the enclosure after hooking it onto the top of the enclosure.
2. Then press the cover with your fingers until it clicks gently into place all over.
3. Fasten the 8 phillips screws.

1. Place the back in the original place.
2. Connect the fingerprint sensor again.
3. Now press the back cover on the whole surface so that the adhesive surface can re-attach.

So that the original glue lasts better, you can warm up your phone again with a hair dryer. If you then clamp the Galaxy S8 or weigh it down with some books, you can further optimise the result.
