Step 2. Remove the tray
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. Open the back cover
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.
ℹ️️ 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 5. Open the middle cover
Remove the cover with antennas and a loudspeaker. The cover protects the printed circuit board (PCB). Try to lift the cover by the edges and not push anything between them to not accidentally touch or short-circuit anything on the PCB.
⚠️ It is crucial while reassembling, checking the spring contacts on the board, and the contact pads on the cover match and touch. Otherwise, signal loss or signal may be quite weak.

Step 6. Disconnect the battery connector
Disconnect the battery connector as soon as possible.
ℹ️️ The Samsung Galaxy A22 SM-A225 model has a battery EB-BA315ABY with 5000 mAh capacity (aka rechargeable battery).
⚠️ It is highly recommended to disconnect the connector to avoid possible short circuits during disassembly.
Also, try not to use a metal tool to disconnect the rechargeable battery connector or do it carefully.

Step 8. Remove the inter-board cable
Carefully, preferably from the edge, disconnect the connectors 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.
ℹ️️ An arrow on the FFC cable (flexible flat cable) indicates its correct position.

Step 10. Disconnect the connector
Disconnect the coaxial cable connector.
⚠️ 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 daughterboard
Remove the sub-board. It is glued to the frame with metalized tape, so to facilitate the process, the sub-board can be heated a bit.
ℹ️️ The sub-board contains a charging port (Micro USB), microphone, headphone jack socket, spring contacts for the speaker, and an antenna unit.
⚠️ It is not necessary to insert the tool underneath when removing the sub-board. Internal components could be damaged.
