How to Disassemble a Cell Phone

By Cameron Easey

When you have an old cell phone that you are no longer using you may want to disassemble the unit to see how it was put together. The process of taking a cell phone apart is basically the same but can vary slightly depending on the type and model of phone that you have. You can disassemble many kinds of cell phones, including units that are available from LG, Motorola and Samsung.

Things You'll Need

  • Phillips head screwdriver
  • Flat head screwdriver
  • Credit card

Step 1

Take the back cover off of the phone. On some phones the back cover may slide off to access the battery or you may need press a button to open a latch.

Step 2

Pull out the battery and remove the memory card, if applicable, for the phone.

Step 3

Remove the small screws located on the back cover with a Phillips head screwdriver. Some screws may be covered by stickers that need to be removed before you can access the screw.

Step 4

Separate the battery compartment to expose the circuit board. Use a small screwdriver that has a flat head or a credit card to separate the sections of the back cover.

Step 5

Unplug the ribbon connectors that are attached to the circuit board.

Step 6

Remove the small screws securing the circuit board and then take it out of the case.

Step 7

Unplug any ribbon connectors that you find. There should be one for a camera, depending on the type of phone, and one for the display.

Step 8

Pull the camera off of the case and then remove the screen.

Step 9

Separate the display screen from the circuit board with the edge of a credit card. Slide the display screen forward to disconnect the ribbon connector from the socket.

Tips & Warnings

  • Use a precision screwdriver that has a magnetic tip so you can easily pick up the small metal screws.
  • One type of cell phone may come apart differently from another.
  • Be careful not to damage the circuit board or any components when disassembling the phone.
