Test Before Installing: Before installing, test the LCD touch screen digitizer assembly. Do not remove any protective film or tags during testing. Be mindful of static electricity. Ground yourself with an ESD (electrostatic discharge) strap to prevent damage to the phone's components. Wear eye protection and handle the glass carefully to avoid cuts. Simulate Testing: Screen replacements are fragile. We strongly recommend simulating testing before installation. This involves connecting the new screen to the motherboard with the audio cable and powering on the device to test functionality. If the test is successful, proceed with installation. If any issues arise, contact us immediately. Do not force the screen into the phone. We are not responsible for damage caused during installation. Avoid Over-Bending the Cable: Do not over-bend the LCD cable. Bending it beyond 90 degrees can cause a black display.
