How to Tear Down/Disassemble the Galaxy S7 for Screen Replacement

As Samsung’s 2016 flagships, the Galaxy S7 and Galaxy S7 Edge were announced on the MWC a few days ago and expected to meet the public in the middle of March. However, some users who pre-ordered these two devices have received and disassembled them already. And we've got one and disassembled it at once, let's take a closer look at what exactly the Galaxy S7 looks like by tearing it down.

 

Tools Needed:

Heat Gun/Hot Plate Machine

Metal Spudger/iSesamo Tool

Plastic Spudger/Prying Tool

Small Phillips Screwdriver

Guitar Picks/Playing Cards

Tweezers


1. Power off the device and remove the Galaxy S7 SIM card tray.

Once you remove the SIM card tray, you'll find it's wearing a waterproof adhesive.


2. Remove the Galaxy S7 back cover.

Heat up along the sides of Galaxy S7 for 1~2 minutes, the back cover is glued to the rear housing with 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, carefuly insert the plastic tip into the back cover and 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.

Now the Galaxy S7 back cover was pulled out from a large portion of strong adhesive as you can see from the below picture, also avoid to hurt the fingerprint sensor in the middle of rear housing while you're heating.


3. Release the Galaxy S7 rear housing set.
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.


4. Pry up the connectors shown in below to release the Galaxy S7 motherboard.

The connetors include: 3 antenna cable connectors, volume button flex connector, power button flex connector, home button flex connector, front facing camera connector, rear facing camera connector, LCD assembly connector, battery flex connector and ear speaker flex connector.



5. Release the Galaxy S7 front housing small parts.

Heat up to soften waterproof adhesive under the Galaxy S7 ear speaker before removing it.

Also, heat up and remove the Galaxy S7 proximity sensor module, where you can also see the water damage detector sticker.

Likewise, heat up to release the Galaxy S7 vibrating motor.


6. Pry up to release the two Galaxy S7 RF signal cables.


7. Release the Galaxy S7 battery.

Heat up to soften the Galaxy S7 battery adhesive, wedge the metal spudger under the battery and pry it back and forth, you may also need a plastic playing card and a plastic spudger to help to remove the battery. The battery is glued to the front housing with strong adhesive in square, that's why the battery is stucking so well.


8. Remove the Galaxy S7 side key flex cable ribbons and side keys.

Pry up to release the earphone jack.
