It is a practical solution for professional repair technicians working on electronic repairs who need to check the behavior of the device's sensors, particularly proximity functions during calls and automatic brightness response to changes in lighting.

- Turn off the device, disconnect the battery and use ESD protection before starting the repair.

- Carefully disassemble the necessary components to access the optical sensor board.

- Compare the arrangement of contacts, connectors and mounting points with the removed part.

- Remove the damaged board while avoiding damage to connectors, contacts and nearby electronic components.

- Clean the installation area and remove adhesive residue where applicable.

- Position the new board according to its original orientation and mounting position.

- Align the contacts and connectors correctly without forcing them or applying excessive pressure to the components.

- Check that the board is correctly seated and that its electrical connections are aligned.

- Temporarily reconnect the battery and test the proximity sensor during a call by moving an object closer to and away from the detection area.

- Verify automatic brightness response by changing the ambient lighting conditions.

- Complete the functional tests before final closure and replace the adhesive materials of disassembled parts where applicable.
