  3. Remove SIM Tray: Use a SIM card ejector tool or a small paperclip to eject the SIM tray from the side of the phone.
  4. Heat the Edges: Use a heat gun or hairdryer to gently heat the edges of the phone. This will soften the adhesive holding the back cover in place.

  7. Disconnect Cables: After removing the screws, you'll need to disconnect any cables or connectors attaching the battery, display, and other components to the motherboard. Use a plastic spudger or your fingernail to carefully lift the connectors away from their sockets.
  8. Lift Out Components: With the cables disconnected, you should be able to lift out the battery, motherboard, camera modules, and other components from the phone's frame.
  9. Reassemble Carefully: If you're replacing any components or performing repairs, make sure to reassemble the phone carefully, following the steps in reverse order. Take your time to ensure all cables are properly connected and screws are tightened securely.
  10. Test the Device: Once reassembled, power on the device and test all functions to ensure everything is working correctly.

1. Be sure to switch off your phone before assembling.

2.Use a paperclip or the key tool (also known as a needle). Pull the SIM and Memory card (Micro SD) tray out by inserting the tip all the way into the hole till the tray ejects.
Keep an eye out! On the edge of the phone's housing, there is a hole that the tool must fit into. Keep your pressure moderate. The tray eject mechanism could become damaged.

3. Carefully pry the back cover's clips off the edge using a spudger or plastic pick, then take it off.
Do not enter the instrument deeply or bend it. Otherwise, it might be tampered with or the housing might get hurt.

4. Remove the six screws with a Phillips 1.5 mm PH000 screwdriver.

5. Take off the printed circuit board (PCB) cover with the antennas. Try to lift the covers by the edges and not push anything between them to not unintentionally touch or short-circuit anything on the PCB.
On the upper cover, you can see the metalized coating on the plastic in the form of tracks and contact pads. These are antennas for Bluetooth, GPS, and Wi-Fi.
Checking that the contact pads on the cover and the spring contacts on the board match and touch is critical while reassembling. Otherwise, signal loss or signal may be relatively poor.

6. Remove the battery connector as quickly as you can.
Battery EB-BA217ABY, also known as a rechargeable battery, has a capacity of 5000 mAh in the Samsung Galaxy A02 SM-A022 model.
Disconnecting the connector is strongly advised to prevent any potential short circuits during disassembly.
Also, try not to use a metal tool to disconnect the rechargeable battery connector or do it gently.

7. Remove the seven screws with a 1.5 mm Phillips screwdriver (PH000).

8. Remove the antenna tracks-covered cover.

9. On the daughterboard, unplug the coaxial wire connector that connects to the mainboard.
The connectors are fairly flimsy and readily break, or the cable falls out of the end (lug), if you tug on the cable or pry it with a sharp object.

Conclusion

 Disassembling the Samsung Galaxy A02 SM-A022 may seem daunting at first, but with the right tools and careful attention to detail, it can be done successfully. By following this comprehensive guide, you'll have the knowledge and confidence to undertake the disassembly process and perform necessary repairs or maintenance on your device.
