For Galaxy A13 4G SM-A135F OEM LCD Screen With Digitizer Full Assembly Before Installation Notes Tip 1: Test before installation. When testing, do not remove any protective film or tags. Please pay attention to 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 to avoid cuts from glass splinters. Tip 2: Simulate testing. Screen replacement is a very fragile product. We strongly suggest testing before installation. Please simulate testing by disassembling the phone, connecting the motherboard, LCD or screen, cable, and the new replacement, then power on to complete the test. If the test is successful, proceed with installation. If the screen does not display, stop immediately. Do not force installation. We will not be responsible once the screen is installed. Tip 3: Do not over-bend the cable. Ensure the LCD cable is not bent beyond 90 degrees, as this may cause a black display. Product Information 1.
