Each item is fully tested before shipment and arrives in good working condition. Precautions before installation: Tip 1: Test the screen before installation. Be aware of static electricity. Ensure ESD (electrostatic discharge) protection is grounded before starting any repair to prevent damage to internal components. Always wear protective glasses to avoid injury from glass fragments.
