4.1. Pre-Installation Checks

1. Inspect the New Digitizer: Carefully inspect the new SRJTEK digitizer for any visible damage, cracks, or defects before installation.
2. Test Before Adhering: Before permanently adhering the new digitizer, connect its flex cable to the tablet's motherboard and perform a preliminary test of touch functionality. Do not remove protective films or adhesive backing until the test is successful.

4.2. Disassembly

1. Power Off: Ensure the tablet is completely powered off.
2. Remove SIM/SD Card: Eject any SIM or SD cards.
3. Heat the Edges: Gently heat the edges of the tablet's screen using a heat gun or hairdryer to soften the adhesive.
4. Pry Open: Carefully use pry tools to separate the old digitizer from the tablet frame. Work slowly around all edges.
5. Disconnect Flex Cables: Once the old digitizer is partially lifted, locate and carefully disconnect its flex cable(s) from the motherboard.
6. Remove Old Digitizer: Completely remove the old, damaged digitizer.
7. Clean Frame: Thoroughly clean any remaining adhesive residue from the tablet frame. This is crucial for a secure bond with the new digitizer.

4.3. Connecting the New Digitizer

1. Connect Flex Cable: Carefully align and connect the new digitizer's flex cable to the corresponding connector on the tablet's motherboard. Ensure it is seated correctly and securely.
2. Preliminary Test: Before applying adhesive, temporarily power on the tablet to test the new digitizer's touch functionality. Test all areas of the screen and ensure responsiveness.

4.4. Reassembly

1. Apply Adhesive: If the preliminary test is successful, remove the protective film from the adhesive strips on the new digitizer (or apply new adhesive if not pre-applied).
2. Secure Digitizer: Carefully align the new digitizer with the tablet frame and gently press it into place, ensuring a firm and even bond.
3. Reassemble: Reassemble any other components that were removed during disassembly.
4. Final Test: Power on the tablet and perform a comprehensive test of all touch functions.

5. Initial Testing and Operation

After installation, perform the following checks to ensure proper operation:

• Full Screen Touch Test: Open an application that allows drawing or a diagnostic tool to test touch responsiveness across the entire screen. Ensure there are no dead spots or unresponsive areas.
• Multi-Touch Gestures: Test multi-touch gestures such as pinch-to-zoom to confirm proper functionality.
• Screen Calibration: If touch input seems inaccurate or inverted, check the tablet's settings for a screen calibration option. Some tablets may require calibration after a digitizer replacement.

6. Care and Maintenance

To maintain the performance and appearance of your new touch screen digitizer:

• Cleaning: Use a soft, lint-free cloth slightly dampened with water or a screen cleaner specifically designed for electronics. Avoid harsh chemicals or abrasive materials.
• Protection: Consider using a screen protector and a protective case to prevent future scratches or impacts.
• Avoid Pressure: Do not apply excessive pressure to the screen, as this can damage the digitizer.
• Temperature: Avoid exposing the tablet to extreme temperatures, which can affect adhesive and component integrity.

7. Troubleshooting

If you encounter issues after installing the SRJTEK touch screen digitizer, refer to the following troubleshooting steps:

• No Touch Response:
  • Ensure the flex cable is securely and correctly connected to the motherboard. A loose or improperly seated connection is a common cause.
  • Check for any visible damage to the flex cable or connector on the digitizer or motherboard.
  • Restart the tablet.
• Inaccurate or Inverted Touch:
  • This can sometimes occur if the digitizer is not fully compatible or if the tablet's software requires recalibration.
  • Check the tablet's display or accessibility settings for a touch screen calibration option.
  • Ensure the correct digitizer model was installed for your specific Facetel Q3 Pro tablet.
  • A factory reset of the tablet (after backing up data) might resolve software-related calibration issues, but this is a last resort.
• Screen Flickering or Display Issues:
  • While this product is a digitizer (touch layer) and not the LCD (display layer), display issues can sometimes be related to improper reassembly or damage to the LCD during the repair process.
  • Ensure the LCD's flex cable is also securely connected.
  • If the issue persists, the LCD itself might be damaged or the connection is faulty.
• Adhesive Not Holding:
  • Ensure the tablet frame was thoroughly cleaned of old adhesive residue before applying the new digitizer.
  • Apply even pressure around the edges after installation and allow sufficient time for the adhesive to cure.

If these steps do not resolve the issue, please contact SRJTEK customer service for further assistance.
