OEM LCD Screen for Asus ZenFone 4 Selfie Pro ZD552KL Z01MD Digitizer Full Assembly with Frame Before Installation Notes Tip 1: Test before installation. When testing, do not remove any protective film or tags. Pay attention to static electricity. Before attempting any repair, ground yourself using an ESD (electrostatic discharge) strap to prevent static damage to internal components. Wear eye protection and handle glass carefully to avoid injury. Tip 2: Simulate testing. Screen replacement is a fragile product. Test the unit before full installation. Partially disassemble the phone, connect the motherboard to the new LCD or screen assembly along with the cable, power on the device, and complete testing. If the screen functions properly, proceed with installation. If there is no display, contact support immediately. Do not force installation. No responsibility is assumed after the screen is installed. Tip 3: Avoid cable over-bending. Ensure the LCD cable is not bent beyond 90 degrees. Excessive bending may result in a black display.
