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.

Screen
Disassembly
When removing the screen, ensure that the device is fixed on a flat surface.
When removing the screen of Galaxy Tab S10 Ultra, you need the 2 heating bags
and a large size suction cup.
1 Heat the 2 microwaveable heating bags for 90 seconds in a 700 W microwave and
apply each one to the front and back of the top left edge of the device for 4 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 2 microwaveable heating bags is 70 seconds for a 1000 W
microwave and 90 seconds for 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.)
If the heating bag is cooled down, 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. When reheating the 2
heating bags simultaneously, they should be heated no longer than 50 seconds.
Disassembly and Assembly
65
2 While maintaining the heating bag under the back of the device, place the suction
cup (L) on the top left edge of the screen, and lift it upward 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. When reheating the 2
heating bags simultaneously, they should be heated no longer than 50 seconds.
Disassembly and Assembly
66
3 While pulling up the suction cup with steady force to create the gap between the
screen and the back cover module, place the opening pick in the gap between the
screen and the back cover module and slide the opening pick back and forth along
the edge to slice through the adhesive. Repeat the same process of applying the
heating bags, placing the suction cup, and the opening pick to separate the screen
adhesive from the top left edge, top right edge, left edge, right edge, bottom right
edge, and bottom left edge. Then, be cautious with the adhesive on the interior side
of the back cover module while gently lifting the screen upwards.
•
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 2 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.
•
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. When reheating the 2
heating bags simultaneously, they should be heated no longer than 50 seconds.
