Heat up along the sides of Galaxy S7 for 1~2 minutes, the back cover is glued to the rear housing with a waterproof adhesive, which is pretty sticky. Pay your patience on this step and make sure the Galaxy S7 back cover adhesive is nicely warm and loosen.

 

 

Pop up the back cover a little bit with the help of a screen separator tool, carefully insert the plastic tip into the back cover and run it along the edges of Galaxy S7 back cover. The adhesive is easily cooled down, you'll need to heat it up back and forth before releasing the back cover. Likewise, be patient.

Undo the 12 long screws in the rear housing. These screws are in the same size, no worries to mix them up. Use a pair of tweezers to pick up the screws if they're still stuck in the holes.

 

 

Remove the Galaxy S7 wireless charging chip and antenna module, be careful not to damage this vulnerable part.

 

 

Peel off the yellow tape and then remove the Galaxy S7 loudspeaker assembly.
