2. Safety Information and Important Notices
- Professional Installation Recommended: Screen replacement requires technical expertise. If you are not experienced in repairing electronic equipment, it is strongly recommended to seek assistance from a professional repair store. Attempting self-replacement without proper knowledge may lead to damage to the screen or your device, which may not be covered under warranty.
- Disconnect Battery Before Installation: Before beginning the installation process, always ensure the device's battery is disconnected. This prevents potential short circuits and damage to the device or the new screen. Reconnect the battery only after the new screen is properly connected.
- Test Before Final Adhesion: Prior to permanently installing the new screen with adhesive, connect it to the device and perform thorough testing. Verify that the display functions correctly, touch response is accurate, and there are no dead pixels or display issues. Do not apply adhesive until you confirm the screen works perfectly. Once adhesive is applied, returns or refunds for functional issues may not be accepted.
- Handle with Care: The screen assembly is made of glass and is fragile. Exercise extreme caution when unpacking the product and during installation to prevent damage from drops or excessive force.
