1. **Pre - installation Test** - During the test, avoid removing any protective films or labels. Be aware of the issue of static electricity. - Before attempting any repairs, ground yourself using an electrostatic discharge (ESD) wristband. This helps prevent static electricity from potentially damaging the electronic components inside the phone. - Wear goggles and handle it carefully to reduce the risk of getting your fingers cut by glass fragments. 2. **Simulation Test** - The screen replacement parts are fragile products. It is recommended to conduct a test before installation. Perform a simulation test, that is, disassemble the phone, connect the (mainboard + battery + LCD or screen) audio cable and the new replacement part, and then power on. After the test is completed, if the test is normal, proceed with the installation. If the screen fails to display, contact us immediately. Do not force it to be installed into the phone. We may not be responsible for any damage to the phone during the installation process. 3. **Do Not Over - Bend the Cable** - Ensure that the LCD cable is not over - bent. A bending angle exceeding 90 degrees may cause the screen to go black. 4. **Advantages** - There is sufficient inventory and relatively fast delivery, which can meet large - scale procurement plans. - It has original - like quality. - It is fully compatible and can work properly.
