5. Setup and Installation

Replacing a touch screen digitizer requires precision and care. It is strongly recommended that this procedure be performed by a qualified technician. If you choose to proceed yourself, please follow these general steps and consult online repair guides specific to the BMobile T70 for detailed visual instructions.

General Installation Steps:

1. Preparation: Power off your BMobile T70 tablet completely. Remove any SIM cards, SD cards, and the back cover if applicable. Disconnect the battery to prevent short circuits.
2. Remove Damaged Digitizer: Carefully heat the edges of the old digitizer using a heat gun or hairdryer to soften the adhesive. Use thin prying tools (plastic spudgers are recommended) to gently separate the old digitizer from the tablet frame. Be extremely cautious around the flex cables.
3. Clean the Frame: Thoroughly clean any remaining adhesive residue from the tablet frame. Ensure the surface is smooth and free of debris for proper adhesion of the new digitizer.
4. Test New Digitizer: Before fully installing, connect the new digitizer's flex cable to the tablet's motherboard connector. Reconnect the battery (do not fully reassemble yet) and power on the tablet. Test the touch functionality across the entire screen to ensure it is working correctly. Power off the device and disconnect the battery again after testing.
5. Apply Adhesive (if not pre-applied): If your new digitizer does not come with pre-applied adhesive tape, apply a thin, even layer of specialized adhesive (e.g., B-7000 glue) around the perimeter of the tablet frame where the digitizer will sit.
6. Install New Digitizer: Carefully align the new digitizer with the tablet frame. Ensure the flex cable is properly routed and not pinched. Gently press the digitizer into place, starting from one side and working your way around, ensuring even pressure for good adhesion.
7. Secure and Reassemble: Once the digitizer is in place, you may use clamps or rubber bands to hold it securely while the adhesive cures (typically a few hours). Reconnect the battery, replace the back cover, and any other components removed during disassembly.

6. Operating Instructions

Once the digitizer is successfully installed and the adhesive has cured, power on your BMobile T70 tablet. The touch screen should respond to your input. Navigate through the device's interface to confirm full functionality across all areas of the screen.

• Perform a multi-touch test if your device supports it.
• Check for responsiveness in all corners and edges of the screen.

7. Maintenance

To ensure the longevity and optimal performance of your new touch screen digitizer:

• Clean the screen regularly with a soft, lint-free cloth. For stubborn smudges, use a screen cleaner specifically designed for electronics.
• Avoid using harsh chemicals, abrasive materials, or excessive force when cleaning.
• Protect your tablet from drops and impacts, which can damage the digitizer. Consider using a protective case and screen protector.
• Keep the device away from extreme temperatures and direct sunlight.

8. Troubleshooting

Common Issues and Solutions:

• Touch screen unresponsive:
  • Ensure the flex cable is securely connected to the motherboard.
  • Restart the tablet.
  • Check for any debris or damage to the flex cable or connector.
• Ghost touches or erratic behavior:
  • This can sometimes be caused by static electricity; try a hard reset.
  • Ensure the digitizer is properly seated and not under uneven pressure.
  • Verify there is no foreign material between the digitizer and the LCD.
• Screen not adhering properly:
  • Ensure the tablet frame was thoroughly cleaned of old adhesive.
  • Apply even pressure during installation and allow sufficient curing time for the adhesive.

9. User Tips

• Watch Repair Videos: Before attempting installation, search for specific repair videos for the BMobile T70 tablet on platforms like YouTube. Visual guides can be invaluable.
• Use Proper Tools: Invest in a basic electronics repair toolkit, which typically includes small screwdrivers, plastic spudgers, tweezers, and suction cups.
• Organize Screws: Keep track of all screws and small parts during disassembly. A magnetic mat or labeled containers can help prevent loss and ensure correct reassembly.
