Replacement touch screen for Y635. Replace your broken or non-functional screen with a new one to restore your device's appearance and performance. Fully compatible and designed to fit properly. Each unit is tested and inspected before shipment to ensure quality. Professional installation is strongly recommended. We are not responsible for any issues arising after installation. Before installation: 1. Test the screen before fully installing. Do not remove any protective films or labels during testing. Be aware of static electricity. Always ground yourself using an ESD (electrostatic discharge) strap before handling internal components to prevent damage. Wear eye protection and handle glass components carefully to avoid injury. 2. Perform a simulation test before final assembly. The screen is a delicate component. Disconnect the phone, connect the new screen to the motherboard and power on to verify functionality. If the screen works properly, proceed with full installation. If there is no display, contact the seller immediately. Do not force installation if the screen does not function. We are not responsible for units installed without prior testing. 3. Avoid excessive bending of the LCD cable. Do not bend the cable beyond 90 degrees, as this may result in display issues such as a black screen.
