Precautions for Repair

Samsung is not liable for any damage to the device, any injuries, or any other device safety issues caused by any attempt to repair the device which does not follow these repair and maintenance instructions, including repairs done by non-authorized service providers, self-repair, or other non-professional repair attempts.

• Use only demagnetized tools that are specifically designed for small electronic repairs, as most electronic parts are sensitive to electromagnetic forces.

• Use only high quality screwdrivers when servicing devices. Low quality screwdrivers can easily damage the heads of screws.

• Always use genuine replacement parts. Third-party replacement parts may not function properly.

• Some parts, such as sensors (laser AF/proximity/fingerprint), the rear camera, the TSP (touch panel), speakers, and other components, may need calibration to guarantee their performance after repair.

• The performance of the device's water and dust resistance cannot be guaranteed when it is repaired by the user or another unskilled worker.

• If you need to access the failure data of your device or need to get a more detailed diagnosis, visit a Samsung Service Center.

• If you need to replace unsold parts, visit a Samsung Service Center and receive further instruction.

• Before conducting repairs, remember to make backup copies of all important data stored in the device.

ESD (Electrostatically Sensitive Devices) Precautions

Many semiconductors and ESDs in electronic devices are particularly sensitive to static discharge and can be easily damaged by it.

• Make sure to discharge static in the work environment before opening packages containing ESDs.
• Increase the airflow to the work area to decrease the chance of accidental static electricity discharges, as the potential for static electricity discharge may be increased in low-humidity environments, such as air-conditioned rooms.
