Setup and Pre-Installation Testing

Before proceeding with the full installation, it is crucial to perform a test of the new screen assembly. This ensures the screen is fully functional before permanent installation and removal of protective films.

Important Notes Before Testing/Installation:

• Professional Installation Recommended: Repairing mobile phone screens requires technical skill. It is highly recommended to seek professional installation or ensure you have sufficient knowledge and experience.

• Do Not Remove Protective Films/Tags: During testing, do not remove any protective films or tags from the screen. Removing them may void the warranty.
• Handle with Care: The screen assembly is fragile. Avoid pulling the flex cables too hard or pressing the LCD panel forcefully, as this can cause damage.
• Power Off and Disconnect Battery: Always ensure your phone is completely powered off and the battery cable is disconnected before attempting any repairs or connections.
