11 steps

Switching off your device
Turn off your device by holding down the power button until the “Power off” option appears.

Use your finger to confirm that you want to shut down your Galaxy S7 and wait until the screen goes blank.
Removing the back cover
The glass back cover is glued to the chassis. Remove the back cover by putting on a suction cup and pulling on it. Also use a pick to push against the frame. Heat your device with hot air beforehand so the glue will be easier to detach.

As soon as a gap appears between the back cover and the chassis, you can insert the pick between the two parts.

The back cover is painted on the inside. Remove any adhesive residue carefully to avoid scratches or cracks.

Use more picks to disconnect all the corners one after the other.

Remove the back cover as soon as all the glue is detached.
Removing the screws
Remove the twelve screws that hold the antennas and the speaker in place.
12 x 3.3 mm PH00 Phillips screws

Remove the yellow adhesive strip.
Removing the upper antenna
Disconnect the upper antenna from the enclosure. The antenna is hooked onto the enclosure. Start at the upper right corner.

As soon as the antenna has come off on the right side, carefully pull it up in the middle so the left side will come off, too.

Remove the antenna from the enclosure.
Removing the middle antenna
Pull the middle antenna out of the enclosure. Note that it’s hooked onto the lower antenna.

Removing the speaker
Disconnect the speaker by using the tweezers to unhook it on the left side.

Remove the speaker from the enclosure.
Installing the speaker
Put the speaker at the lower end of the enclosure.

Press on the speaker with your fingers until it clicks into place in the enclosure.
Installing the middle antenna
Put the antenna back in the enclosure after hooking it onto the lower antenna.

Press on the antenna with your fingers until it clicks into place in the enclosure.
Installing the upper antenna
Put the antenna back in the enclosure. First put it on the left side and then press it on firmly with your fingers.

You should be able to hear the antenna click into place.
Fastening the screws
Put the yellow adhesive strip back on.

Attach everything using the screws.
12 x 3.3 mm PH00 Phillips screws
Attaching the back cover
Put the back cover back in its original position.

Press the back cover on all over so the glue will stick.

You can also heat your device with hot air and then clamp it or weight it down with a couple books so the glue will stick better.
