Precautions before installation Tip 1: Test before installation Do not remove any protective film or label when testing. Please pay attention to the problem of static electricity. Before attempting any repair, always ground an ESD (electrostatic discharge) wrist strap. This will prevent static electricity from damaging the electronic components inside the phone. Make sure to wear goggles and be careful not to cut your fingers with glass fragments. Tip 2: Simulation test Screen replacement is a very fragile product. We strongly recommend testing before installation. Please simulate testing, which means take the phone apart, (motherboard + LCD or screen) connect the audio cable and the new replacement power supply, test it. If the test is OK, please install it. If it can't display, please contact us for the first time. And please don't force it to install it on the phone. We will not be responsible once the screen is installed. Tip 3: Don't over-bend the cable Make sure the LCD cable does not over-bend. Bending more than 90 degrees will cause the display to turn black.
