Before Installation Notes for iPhone 15 Incell LCD with Digitizer Tips for Safe Installation: Tip 1: Test Before Installation Before proceeding with the installation, check that the screen functions properly. Do not remove any protective film or tags while testing. To prevent damage from static electricity, ground yourself with an ESD (electrostatic discharge) strap. Always wear eye protection and handle the glass carefully to avoid cuts from splinters. Tip 2: Simulated Testing Due to the fragile nature of screen replacements, we highly recommend simulating a test before installation. Disconnect the current screen and connect the new LCD and digitizer assembly to the motherboard using the audio cable. Power on the device to verify that the display functions correctly. If everything works as expected, you can proceed with the installation. If there are issues (e.g., no display), contact us immediately, and do not attempt to install the screen. Tip 3: Avoid Over-Bending the Cable Be cautious with the LCD cable to avoid damaging it. Do not bend the cable more than 90 degrees, as excessive bending may lead to a black display.
