Package Include: LCD Display Touch Screen Digitizer  Tool Set Before Installation Notes Tips 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 with the glass splinters. Tips 2: Simulates testing Screen replacement is a very fragile product. We strongly suggest testing before installation. Please simulate testing, which means mobile phone apart, (motherboard + LCD or screen) connected audio cable and new replacement, power on, test finished. If the test is OK, please install it. If it can not show, please contact us at the very first time. And please do not force it to be installed on your mobile phone. We will not be responsible once the screen is installed. Tips 3: Do not over-bend cable Please make sure the LCD cable does not over-bend. Over 90 degrees bent will cause a black display.
