Samsung reserves the right to alter this document or the device described herein at any time, without obligation to provide notification of such changes.

Precautions for Repair
Samsung is not liable for any damage or defect determined to be caused by repair by a non-authorized carrier, self repair or non-professional repair of the device. Samsung is not liable for any resulting damage to the device, or any injury or other device safety issue caused by any attempt to repair the device which does not follow these repair and maintenance instructions.
Any damage to the device or defect caused by an attempt to repair the device by any person other than a Samsung certified carrier will not be covered by the warranty.

• 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 and could cause a fire or injury.

• 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.

• Make sure to wear the appropriate safety equipment before carrying out repairs.
  Samsung is not responsible for injuries that may occur because of not wearing the proper safety equipment. Refer to Tools for Disassembly and Assembly for a list of tools that you will need for assembling and disassembling the device.

• Repair the device in a safe place.

• Before repairing the device, make sure the device is turned off. To turn off the device, press the Volume Down button and the Side button at the same time, or open the notification panel and tap the Power icon.

• If the device is damaged, emits smoke, or if you smell something burning, stop using the device immediately and contact Samsung.

• It is recommended to use safety equipment such as glasses, gloves, and a mask when repairing the device.

• Be careful not to damage the device when removing the back cover.

• Before assembly, ensure that there are no screws or foreign objects around the battery.

• During assembly, check if there are any abnormalities before reattaching the back cover, and be careful not to damage the battery by hitting or denting it. If the battery is damaged, visit a Samsung Service Center.

• Do not place the device directly into a microwave and heat it.

• Before repairing your device, make sure its battery is fully discharged.

• Visit www.samsung.com to view the device information, related material, and safety information.

ESD (Electrostatic Discharge) Precautions
It is the sudden flow of electricity between two electrically charged objects caused by contact, an electrical short, or dielectric breakdown. ESD can cause negative effects on mobile phone, especially electrical parts.

• It is recommended to use ESD safety (Anti-static) equipment such as an anti-static wrist strap and gloves, and an ESD safe mat when repairing the device.
• 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.

Disassembly for Replacement

Before disassembling:

• Unplug and turn off device before disassembling.
• Remove the SIM card tray from the device.
• Wear an anti-static wrist strap and connect it to the grounded ESD safe mat.
• The product’s composition may vary depending on the country, region, or carrier.

For all cases of broken glass:

1. Wear safety goggles and cut-resistant gloves.

2. Remove the release film of the acrylic protective cover.

3. To prevent injuries and scattering caused by broken glass, attach an acrylic protective cover.
   If your device’s glass breaks, be careful not to injure your hands or other body parts on debris.

4. Press the acrylic protective cover with strong force so that it is strongly attached to the glass.
   Wait more than 5 minutes until the bond between the acrylic protective cover and the glass is strengthened.

5. Follow the disassembly steps in this guide.
   Screen glass cannot be separated alone from the AMOLED screen or metal frame.
   If the glass is broken, it needs to replace the whole screen module.

SIM Card Tray Remove

1. Prepare the device to repair by yourself.
2. Insert the ejection pin into the hole of the SIM card tray to loosen the tray and pull out the tray gently from the tray slot. After you finish disassembling, refer to SIM Card Tray Assembly for how to reassemble.

Volume Button Remove

• The buttons are already included in the screen module. Replace them only if they need to be repaired.
• The Side button has a built-in fingerprint recognition sensor. Thus, it cannot be removed directly from outside.

1. Press one end of the Volume button with your fingers lightly so that the other end protrudes.

2. Push the tip of the protruding button up carefully with the tweezers and lift it up until you can grab it with your fingers.
