Before Installation Notes 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 (electro static 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 with the glass splinters. ②. Simulates testing Screen replacement is a fragile product. It is suggested to test before installation. Please perform simulated testing, which means separating the mobile phone, connecting the audio cable and new replacement to the motherboard + LCD or screen, powering on, and finishing the test. If the test is OK, please install it. If it cannot show, please contact us at the first time. Do not force it to be installed in the mobile phone. Responsibility will not be taken once the screen is installed. ③. Do not over-bend cable Please make sure the LCD cable is not over-bent. Bending over 90 degrees will cause black display.
