Disassembling Samsung

Disassembling Samsung
Want to change your broken screen (my condolences) or you`re just eager to know how your phone looks on the inside? You came to the right place.


Tools required for disassembly: screwdriver, plastic tool such as a guitar plectrum or credit card
SAMSUNG GALAXY S
  • Remove your back cover, battery, sim and memory card. Seven screws need to be removed. The screw circled in white is a different size to the others so make sure it goes back in the right place.

  • Run something like a credit card around the join of the battery compartment to release it from the rest of the phone.

  • With the battery compartment removed your phone should look like below. A number of ribbon connectors (circled) need to be disconnected. Each attaches like a plug and socket. Just lever each one up to unplug. The power button, indicated by the arrow, is stuck to the side of the phone's housing and should be carefully lifted away, being careful not to damage it. Do not try to disconnect it from the circuit board you just need to make sure it's not stuck to the side of the phone. You'll now be able to remove the circuit board simply by lifting it away from the rest of the phone.

  • With the circuit board removed your phone should look like below. The hands free socket and earpiece, circled below, can now be lifted away from the phone. The part is held in place with a little double sided tape and will peel away with little force.

  • With the hands free socket and earpiece removed your phone should look like below. The ringer, circled below left, needs to be levered away from the phone. It's held in place with double sided tape. Just use your screwdriver to carefully lever it up. It will still be connected by two wires. Be careful not the damage these two wires. Two more ribbon connectors (circled centre and right) also need to be disconnected. Each attaches like a plug and socket. Just lever each one up to unplug.

  • Now slide something like a credit card between the front and back of the phone and carefully lever the phone apart.

  • Your phone should now look like below. The next stage is to remove the screen. To do so first heat the front of the screen around its edge with a hot air gun or hairdryer. Then push the back of the screen from the point indicated by the arrow. The screen should then raise slightly on the other side, enough for your to slide your plastic tool under its edge and separate it from the silver frame.

  • Next, slide something thin and flat all the way round the join of the front cover in an anti clockwise direction, as shown below. This will release the battery compartment.

  • With the battery compartment removed, your phone should look like below. Six ribbon connectors, circled below, need to be disconnected. Each attaches like a plug and socket. Just lever each one up to unplug. On the left and right side of the phone are the power and volume micro switches, indicated by the arrows below. These are permanently connected to the circuit board but are stuck to the side of the housing with double sided tape. Carefully peel them away from the side of the housing, leaving them connected to the circuit board.

  • Below you can see the blue circuit board has been removed. Use your screwdriver to lever the ringer and earpiece from the points indicated by the arrows below.

  • With the ringer and earpiece removed your phone should look like below. Another ribbon, indicated by the arrow, needs to be peeled back. It's held in place with double sided tape. The front facing camera, circled below, should be lifted up slightly. To remove the screen you first need to apply some heat to the front of the screen using a hot air gun or hair dryer. Do this for about 60 seconds. Then push your screwdriver into the recess where the front facing camera sits. This will raise the screen slightly from the other side, allowing you to slide your plastic tool under it.

  • Run your plastic tool under one side of the screen, indicated by the dashed line. Keep away from the area below the screen or you will damage the home button ribbon cable. Keep applying more heat to the screen and it will start to free.

  • Now push your plastic tool right under the screen, as shown below. Keep applying more heat and the screen will gradually free.

s212.PNG
  • The ribbon cable has now been removed and the home button itself will simply fall out of the back of the screen, as shown below. Disassembly is now complete. Reverse the whole procedure for reassembly.
