To operate a mobile screen separator, you generally follow these steps:

1. **Safety Precautions:** Ensure the device is powered off and take necessary safety precautions to protect yourself and the phone.

2. **Disassembly:** Disassemble the phone, removing screws and components to access the damaged screen.

3. **Heating:** Use a heat source or a specialized heating pad to gently warm the edges of the screen. This softens the adhesive holding the screen in place.

4. **Separation Tools:** Utilize specialized tools, like plastic picks or suction cups, to carefully pry the screen away from the device. Take your time and work methodically to avoid damaging other components.

5. **Disconnect Cables:** Once the screen is partially separated, disconnect any cables connecting it to the device.

6. **Replacement:** If replacing the screen, attach the new one by reconnecting cables and securing it with adhesive. If repairing, address the issues and reattach the original screen.

7. **Reassembly:** Put the phone back together, securing screws and ensuring all components are properly connected.
