Disassembly/Repair of the mobile device Realme C3 (Realme C3 RMX2027) with each step description and the required set of tools.

⚠️ Before disassembling, do not forget to turn your phone off.

Use an 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.

Using a spudger or a plastic pick, carefully, around the edge, detach the back cover clips, and remove it.

Do not insert the tool deeply or bend it. Otherwise, the housing may be tampered with or damaged.

Using a screwdriver (Phillips 1.5 mm PH000), unscrew 11 screws.

Remove the cover with antennas that protect the printed circuit board (PCB). Try to lift the covers by the edges and not push anything between them to not accidentally touch or short-circuit anything on the PCB.

Pry up the connector and remove the fingerprint sensor.

Disconnect the battery connector as soon as possible.

ℹ️️ The Realme C3 RMX2027 model has a battery BLP729 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.

Using a screwdriver (Phillips 1.5 mm PH000), unscrew 9 screws.

Remove the loudspeaker assembly with antennas.

Disconnect the coaxial cable connector, cable to the mainboard, 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).

Remove the sub-board. It is glued to the frame with metalized tape, so to facilitate the process, the board can be heated a bit.

ℹ️️ The 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 under the board when removing the sub-board. Internal components could be damaged.

Carefully remove the battery.

Pry up connectors, remove three rear cameras and one front (selfie) camera.

Pry up the connectors of the display module cable, inter-board cable, and coaxial cable.

⚠️ 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.

Carefully remove the printed circuit board. There is no need to use a lever or try to reach the board by force. Make sure that nothing is getting in the way or holding the 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.
