All functionality, features, specifications, and other device information provided in
this document, including but not limited to, benefits, design, pricing, components,
performance, availability, and capabilities of the device are subject to change without
notice. 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-authorised 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 demagnetised 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 Centre.
•
If you need to replace unsold parts, visit a Samsung Service Centre 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 Centre.
•
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 devices, 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 and Reassembly for replacement
•
The product’s composition may vary depending on the country, region, or
carrier.
•
Repairable parts may vary depending on the country or region.
Before disassembling:
•
Unplug and turn off device before disassembling.
•
Wear an anti-static wrist strap and connect it to the grounded ESD safe mat.
Before reassembling:
•
Remove the adhesive tape residues perfectly.
•
Prepare all existing screws of this device and adhesive tapes.
•
Wear an anti-static wrist strap and connect it to the grounded ESD safe mat.
•
Leaving screws inside the device may damage internal components, such as the
battery. When assembling, be extra careful not to leave any unassembled screws
inside the device.
For all cases of broken glass:
1 Wear safety goggles and cut-resistant gloves.
2 To prevent injuries and scattering caused by broken glass, attach the tape on the
broken glass.
If your device’s glass breaks, be careful not to injure your hands or other body parts
on debris.
3 Press the tape with strong force so that it is strongly attached to the broken glass.
Wait until the adhesive between the tape and the glass is strengthened.
4 Follow the disassembly steps in this guide.

Screen
Disassembly
When removing the screen, ensure that the device is fixed on a flat surface.
1 Heat the microwaveable heating bag and apply it on the top edge of the screen for
3 minutes.
•
It is possible for the device or battery to be damaged by heat.
•
Do not heat the device in a microwave. Doing so could cause an explosion.
•
If your device’s glass breaks, the debris can cause injury to your hands or
other body parts. For your safety, attach the tape on the broken glass before
disassembling the device.
•
Follow the heating bag’s instructions for heating. The recommended time for
heating the bag is 50 seconds in a 1000 W microwave and 70 seconds in a 700 W
microwave. (Correct temperature for use: 55-65 ℃.)
•
Be careful not to damage the device through excessive heat. (It is
recommended to disassemble the device in an area with a temperature gauge.)

2 Place the suction cup on the top left edge of the screen, and lift it upwards carefully.
•
As the screen can be damaged by excessive force, be careful not to damage the
screen.
•
Be careful that the suction cup does not adhere to the area where the tape or
sticker is attached.
If you have trouble creating a gap, heat the microwaveable heating bag
additionally, and apply it on the screen to further soften the adhesive. When
reheating, it should be heated no longer than 30 seconds.
Disassembly and Assembly
61
3 While pulling up the suction cup with strong, steady force to create the gap between
the screen and the back cover module, place the opening pick in the gap between the
edge of the screen and the back cover module and slide the opening pick back and
forth along the edge to slice through the adhesive. Repeat this on the all sides and
slice through the adhesive. Lift up the screen slowly and carefully.
Be careful when inserting the opening pick too deeply as this could damage the
internal circuitry, leading to problems such as abnormal operation of the screen.
•
As the screen can be damaged by excessive force, be careful not to damage the
screen.
•
As the internal circuitry can be damaged, do not insert the opening pick more
than 1–2 mm.
•
In case of the bottom edge side of the screen, very weak circuits are located
very close to the edge. Just insert only about 1 mm.
•
Make sure to leave the opening pick inserted in the edges to prevent the
adhesive from resealing. It is recommended that a large area of the opening
pick be inserted.
•
To prevent the adhesive from resealing, change the location of the inserted
opening picks properly according to the adhesive state of the screen.
•
If you have trouble creating a gap, heat the microwaveable heating bag
additionally, and apply it on the screen to further soften the adhesive. When
reheating, it should be heated no longer than 30 seconds.
