For Galaxy Tab S4 10.5 SM-T830 T835 Front Screen Outer Glass Lens (Black) Before Installation Notes 1. 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 (electro static discharge) strap. This will prevent static electricity from damaging the electronic components within the device. Ensure you wear eye protection and use caution not to cut your finger with glass splinters. 2. Tips 2: Simulate testing Screen replacement is a very fragile product. We strongly suggest testing before installation. Please simulate testing by disassembling the mobile phone, connecting the motherboard, LCD or screen, o cable, and the new replacement, then powering on to complete the test. If the test is successful, proceed with installation. If there is no display, contact the seller immediately. Do not force installation. Responsibility is not assumed once the screen is installed. 3. Tips 3: Do not over-bend cable Please ensure the LCD cable is not over-bent. Bending beyond 90 degrees may cause a black display. About the product 1.
