Before we delve into the disassembly process, it’s crucial to gather the necessary tools and establish a clean and well-lit workspace. Here’s what you’ll need:

A prying tool (plastic spudger or opening picks are recommended)

  • A precision screwdriver set (including a Torx screwdriver)
  • A suction cup (optional, but helpful)
  • A clean, microfiber cloth
  • A shallow container for screws and small components

  • Power Down and Remove the SIM Card Tray

    For safety reasons, always ensure your Realme C21Y is completely powered down before attempting any disassembly. Locate the power button and hold it down until the power menu appears on the screen. Select “Power off” and wait for the phone to shut down entirely.

    Next, identify the SIM card tray on the side of the phone. Use the dedicated SIM ejector tool that came with your phone, or a straightened paperclip, to gently push in the small hole beside the tray. The tray should pop out slightly, allowing you to remove it completely. Take note of the orientation of the SIM card(s) inside the tray for proper reassembly later.

    Heating the Back Panel (Optional)

    The Realme C21Y’s back panel is likely secured with adhesive. Applying some heat can help soften the adhesive and make the removal process easier. A hairdryer set to low heat is a suitable tool for this purpose. However, be cautious not to overheat the device, as this could damage internal components. Briefly and evenly heat the back panel for about a minute, focusing on the edges where the panel meets the frame.

    Prying Up the Back Panel

    Now comes the delicate task of separating the back panel from the phone’s frame. Here’s where your prying tool comes in handy. Insert the thin edge of the prying tool between the back panel and the frame, ideally along the bottom edge. Be very gentle and avoid using excessive force, as this could crack the glass back panel. Pry up slowly and carefully, working your way around the entire perimeter of the phone. You might hear slight clicking sounds as the adhesive breaks loose.

    Using a Suction Cup (Optional)

    If you find it challenging to pry open the back panel with just a tool, a suction cup can provide additional leverage. Attach the suction cup to a smooth, flat area on the back panel (avoiding the camera lens). Gently pull upwards on the suction cup while simultaneously inserting your prying tool in another area to create a gap.

    Disconnect the Fingerprint Sensor Cable (Optional)

    Some variants of the Realme C21Y might have a fingerprint sensor embedded in the back panel. If yours does, you’ll need to disconnect the fingerprint sensor cable before completely removing the back panel. Locate the fingerprint sensor connector on the motherboard (usually near the bottom) and identify the cable attached to it. Carefully use your fingernails or a plastic spudger to pry the connector up from its socket on the motherboard.

    Unscrew the Internal Components

    Once you’ve successfully removed the back panel, you’ll be presented with the phone’s internals. Locate the screws holding the various components in place, such as the speaker module, daughterboard, and battery connector. Use your precision screwdriver set to remove these screws carefully, placing them in your designated container to avoid losing them during reassembly.

    Remember, these are just the initial steps. Keep reading for the following sections on disconnecting cables, removing the battery, and reassembling your Realme C21Y!
