Precautions before Installation 1. Tip 1: Test before Installation Do not remove any protective film or label when testing. Please pay attention to static electricity issues. Before attempting any repair, always ground yourself with an ESD (electrostatic discharge) strap. This will prevent static electricity from damaging the electronic components within the phone. Make sure to wear eye protection and be careful not to cut your fingers on glass shards. 2. Tip 2: Simulated Testing Screen replacement is a very fragile product. We strongly recommend testing before installation. Please simulate the test, that is, disassemble the phone, (motherboard + LCD or screen) connect the audio cable and the newly replaced one, turn on the phone, and the test is completed. If the test is normal, please install it. If it cannot be displayed, please contact us as soon as possible. Do not force it to be installed in the phone. Once the screen is installed, we will not assume any responsibility. 3. Tip 3: Do not over-bend the cable Please make sure that the LCD cable is not over-bent. Bending more than 90 degrees will cause a black screen.
