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 is 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 very fragile product. We strongly suggest test before installation. Please simulates testing, which means mobile phone apart, (motherboard + LCD or screen)connected audio cable and new replacement, power on, test finished. If test OK, please install it.
