Before Installation Notes Tips 1: Test before installation Do not remove any protective film or tags when testing. Be cautious of static electricity issues. Before attempting any repair, ensure you ground yourself with an ESD (electrostatic discharge) strap to prevent any damage to the electronic components within the phone. Wear eye protection and be careful of glass splinters. Tips 2: Simulated testing Screen replacements are very delicate. We highly recommend testing prior to installation. This means separating the mobile phone, connecting the motherboard + LCD or screen with the audio cable and the new replacement, powering on, and finishing the test. If the test is successful, proceed with the installation. If it does not display, contact us immediately. Do not force installation into the mobile phone. We will not be responsible once the screen has been installed. Tips 3: Avoid over-bending the cable Ensure the LCD cable is not over-bent. A bend greater than 90 degrees can cause a black display.
