Step 1.
⚠️ Before disassembling, do not forget to turn your phone off.
Step 2.
Use the ejection tool (aka Needle) or Paperclip. Push the tip all the way into the hole until the tray ejects, and then pull the tray of SIM and Memory card (Micro SD) out.
⚠️ Pay attention! The tool must be inserted into a hole on the edge of the phone's housing. Do not press too hard. It may break the tray eject mechanism.
Step 3.
We recommend using a special heating device such as a separator machine, heat gun, or heating mat. It will simplify the process. You can use a home hairdryer, but you will have to make a nozzle by hand or have a suitable one in the kit to gently heat and concentrate the heat flow in the right place.
ℹ️ The surface of the back cover must be heated to soften the adhesive underneath. The approximate heating temperature is 50° C / 125° F.
Use a thin plastic film or pick for separation. To facilitate the process, you can use isopropyl alcohol. It is often most difficult to pass the tool between the parts to be divided. Choose the far edge from the FFC cables or buttons.
Do not use a lever or any force for separation that could damage the elements inside.
Step 4.
Using a screwdriver (Phillips 1.5 mm PH000), unscrew 16 screws.
Step 5.
Pry up the edges. Move an opening tool along the edge detaching the clips and lift the middle cover with a fingerprint sensor and antenna pads and tracks. The middle cover protects the printed circuit board (PCB).
Try to lift the cover by the edges and don't push anything too far inside, so as not to accidentally break or short-circuit anything on the circuit board.
Step 6.
Pry up the fingerprint sensor connector and remove the middle cover. It is better to use a non-metal or plastic tool to avoid any damage.
Step 7.
Disconnect the battery connector as soon as possible. It is better to use a non-metal or plastic tool to avoid any damage.
ℹ️ The Samsung Galaxy A22s SM-A226 model has a battery EB-BA226ABY with 5000 mAh capacity (aka rechargeable battery).
⚠️ It is highly recommended to disconnect the connector to avoid possible short circuits during disassembly.
Step 8.
Using a screwdriver (Phillips 1.5 mm PH000), unscrew three screws.
Step 9.
Remove the loudspeaker assembly with antennas.
Step 10.
Disconnect connectors for two coaxial cables, inter-board sub-screen cable on the daughterboard.
⚠️ Do not pull on the cable or pry it with a sharp tool. The connectors are pretty weak and break easily, or the cable falls out of the end (lug).
Step 11.
Remove the sub-board. It may be glued to the frame with metalized tape, so to facilitate the process, the sub-board can be heated a bit.
ℹ️ The sub-board contains a charging port (Micro-USB), microphone, headphone jack socket, spring contacts for the speaker, vibration motor and an antenna unit.
⚠️ It is not necessary to insert the tool underneath when removing the sub-board. Internal components could be damaged.
Step 12.
Carefully, preferably from the edge, disconnect the connector and remove the inter-board cable connecting the mainboard to the daughterboard (also known as the sub-board).
⚠️ Be careful when removing the cables from the connectors. The cables are pretty thin, and it is easy enough to break them or damage the contact tracks inside.
ℹ️ An arrow on the FFC cable (flexible flat cable) indicates its correct position.
Step 13.
Using a screwdriver (Philips 1.5 mm PH000), unscrew one screw.
Step 14.
Disconnect the connectors and remove one rear camera and one front (selfie) camera.
Step 15.
Pry up the connectors of the display module cable, two coaxial cables.
⚠️ Be careful when removing the cables from the connectors, the cables are pretty thin, and it is easy enough to break them or damage the contact tracks inside.
Step 16.
Carefully remove the printed circuit board. There is no need to use a lever or try to reach the circuit board by force. Make sure that nothing is getting in the way or holding the circuit board.
⚠️ Do not bend the circuit board when removing it or push tools under it. Unbeknownst to yourself, you can damage components or cables from the inside.
Step 17.
Pry up the connectors and remove the two rear cameras.
