A set of prying tools (plastic spudgers are recommended to avoid scratches)

  • A hairdryer or heat gun (optional, for loosening adhesive)
  • A Phillips head screwdriver
  • A clean, well-lit workspace

  • Remember, opening your phone voids the warranty. Proceed with caution and only if you’re comfortable with delicate procedures. If you’re unsure, consider seeking professional help from a qualified technician.

    Power Down and Data Backup

    For safety reasons, always power down your Realme U1 completely before attempting to open it. Locate the power button and hold it down until the power menu appears. Select “Power off” and wait for the phone to shut down entirely.

    This is also an excellent time to back up your data. Transfer important files, photos, contacts, and messages to an external storage device or cloud storage service to prevent accidental data loss during the opening process.

    SIM Tray Removal

    The SIM tray usually houses the SIM card(s) and sometimes an SD card. Locate the SIM tray slot on the side of your Realme U1. It’s typically a small hole with an eject symbol. Use the dedicated SIM eject tool, often included with your phone’s purchase, or a straightened paperclip to gently press into the hole. The tray should pop out slightly.

    Carefully pull out the SIM tray and remove any SIM cards or SD cards present. This step disconnects the phone from cellular networks and external storage, making the disassembly process safer.

    Back Cover Removal

    The back cover of the Realme U1 is likely secured with adhesive. Here’s where your prying tools come in handy. Be very gentle as you pry around the edges of the back cover, separating it from the phone’s frame. It’s helpful to apply localized heat using a hairdryer or heat gun (on a low setting) if the adhesive feels particularly strong.

    Pro Tip: Focus on one edge at a time, carefully inserting the prying tool between the back cover and the frame. Slide the tool along the edge, gradually prying the back cover loose. Avoid using excessive force or levering the tool against the phone’s frame, as this can cause cracks or damage the internal components.

    Locate the Screws

    Once you’ve successfully detached the back cover, you’ll likely find a few Phillips head screws securing the internal components. Use your screwdriver to remove these screws carefully, placing them in a designated container to avoid losing track of them during reassembly.

    Fingerprint Sensor and Ribbon Cable

    The fingerprint sensor on the back of the Realme U1 might be connected to the motherboard with a small ribbon cable. Identify the connector where the cable attaches to the motherboard and locate the locking mechanism (usually a small clip or tab). Carefully unclip or lift the tab to disconnect the ribbon cable without damaging it.

    Battery Disconnection

    The battery is a vital component and requires careful handling. Locate the battery connector on the motherboard. It’s typically a flat, rectangular connector with a small latch or clip. Similar to the fingerprint sensor cable, gently unclip or lift the latch to disconnect the battery from the motherboard.

    Internal Components

    With the back cover, screws, fingerprint sensor cable, and battery disconnected, you should now have access to the Realme U1’s internal components. These may include the motherboard, cameras, speaker modules, and other components. Avoid touching or handling any of these components unnecessarily, as electrostatic discharge (ESD) can damage sensitive electronics.

    Note: This is the point where you can access the desired component for replacement or repair. Consult a professional repair guide or service manual specific to the Realme U1 for detailed instructions on disassembling and replacing specific components.


    Once you’ve completed your repairs or replacements, it’s time to reassemble the Realme U1. The process is essentially the reverse of disassembly. Ensure all components are correctly positioned and secured before reattaching the battery and fingerprint sensor cable. Remember to screw everything back in place and replace the back cover, pressing down firmly to ensure proper adhesion.
