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.

Digital Hall Sensor Calibration (Fold and Flip Models Only)
Whenever the screen is replaced, the digital hall sensor must be calibrated to guarantee
optimised digital hall sensor performance for devices that have it.
Digital hall sensor calibration is available through the
Self Repair Assistant
app.
•
This feature may not be available depending on the model. The availability of
this feature can be automatically checked in the Self Repair Assistant app, so
please follow the guidance of the Self Repair Assistant app.
•
For Fold models: If the main screen does not turn on after being replaced (the
main screen is off and the cover screen is on when the device is unfolded),
follow the steps below to perform digital hall sensor calibration. The boot
screen (the screen where the Samsung and carrier logos appear) will appear
normally and then turn off, so it is not a hardware failure.
1) Fold the device and launch the
Self Repair Assistant
app on the cover
screen.
2) Move to the digital hall sensor calibration screen, unfold the device, and
then press the Volume Up button or the Volume Down button.
3) You will hear a vibration, and the calibration will be performed
automatically.
When calibration is complete, the main screen will turn on normally.
•
For Flip models: If the main screen does not turn on after being replaced (the
main screen is off and the cover screen is on when the device is unfolded),
follow the steps below to force the main screen to turn on and perform digital
hall sensor calibration. The boot screen (the screen where the Samsung and
carrier logos appear) will appear normally and then turn off, so it is not a
hardware failure.
1) Connect the USB cable to the device, and connect the other end of the USB
cable to the USB power adapter or your computer.
2) While pressing and holding the Side button, press the Volume Up button
once and the Volume Down button twice.
3) When the main screen turns on, perform digital hall sensor calibration.
