For Samsung Galaxy S21 FE 5G SM-G990B 6.43 inch EU Version OLED LCD Screen Digitizer Full Assembly with Frame (Black)Before Installation NotesTips 1: Test before installation When testing, do not remove any protective film or tags. Please pay attention to the problem of 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 not to cut your finger on glass splinters.Tips 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, audio cable, and new replacement, then powering on to complete the test. If the test is successful, proceed with installation. If there is no display, immediately. Do not force installation into the phone. We will not be responsible once the screen is installed.Tips 3: Do not over-bend the cable Please ensure the LCD cable is not over-bent. Bending beyond 90 degrees may cause a black display.About the Product 1.
