Before Installation Notes 1. Tips 1: Test before installation When testing, do not remove any protective film or tags. Please pay attention to the problem of static electricity. Before attempting any repair, be sure to ground yourself with an ESD (electrostatic discharge) strap. This will prevent static electricity from damaging the electronic components within the phone. Ensure you wear eye protection and use caution not to cut your finger with glass splinters. 2. Tips 2: Simulated testing Screen replacement is a very fragile product. We strongly suggest testing before installation. Please perform simulated testing, which means disassembling the mobile phone, connecting the motherboard, LCD or screen, audio cable, and new replacement, then powering on to test. After testing is complete, if the result is satisfactory, proceed with installation. If there is no display, please immediately. Do not force the installation into the mobile phone. We will not be responsible once the screen is installed. 3. Tips 3: Do not over-bend the cable Please make sure the LCD cable is not over-bent. Bending beyond 90 degrees may cause a black display.
