Samsung Galaxy Note 8 screen repair guide

The screen of your Galaxy Note 8 is broken or remains black?

With this detailed step-by-step guide, you can easily replace your Galaxy Note 8 display at home.

A replacement is necessary when the glass is shattered, the touchscreen does not respond to touch anymore, or the display remains black or flickers. During this repair, we replace the entire display unit including the frame, not just the broken screen. You may have to take some small parts from the old display unit, depending on how the new spare part is equipped.

The repair is a bit difficult as the Galaxy Note 8 has to be opened via the glass backcover. Unfortunately, this is a rather cumbersome procedure, so plan enough time for it.

Do a backup before the repair, use a clean work surface and reserve enough time. If you are stuck at any point, just contact our live chat or write a comment on the corresponding step.

32 steps

Switching off your device
Turn off your device by holding down the power button until the “Power off” option appears.
Use your finger to confirm that you want to shut down your Galaxy Note 8 and wait until the screen goes blank.
In the pictures you can see a Galaxy S9, because the screen of our Note 8 didn't show anything.
Removing the back cover
The back cover’s really glued to the chassis. Heat the device evenly with hot air to soften the glue. A temperature of 60 - 80°C should be sufficient. As a rule of thumb, you should still be able to touch your device without it being uncomfortably hot.
The easiest way to loosen the back cover is to use a flat and flexible tool such as the iPlastix or iFlex. You will also need several picks to unstick the back cover all around.
Heat the spot where you start and place a flat tool between the back cover and the frame.
The iPlastix is made of plastic, so it won't scratch the device. On the other hand, it's very soft and tricky to insert.
Be extra careful, the back cover can break very easily. If necessary, apply the heat several times and try again. Removing the back cover might take half an hour. Take a little more time and work carefully to make sure you don't break anything.
Once the tool is inserted, stick a pick into the gap to keep it open. Then run the tool around the entire edge to gradually loosen the glue.
Then heat the next part and insert the picks one by one.
The back cover glue is extra strong on the lower edge.
Once the back cover is loosened, lift it very slightly. The fingerprint sensor underneath the camera is still connected with a cable.
Use a suction cup to lift the glass if you can’t find anywhere to insert the tool
Disconnecting the fingerprint sensor
After detaching the back cover, carefully lift it and disconnect the fingerprint sensor using the spudger.
Then you can completely remove the back cover and set it aside.
Removing the NFC antenna
10 × 3,7 mm Phillips

Remove the screws that attach the upper cover to the display.
The cover is latched onto the case, the lower part of the antenna is lightly glued in place. Slide a flat tool under the latches to disconnect them.
Now remove the antenna.
Disconnecting the battery contact
Battery connector

Using the spudger, carefully disconnect the battery contact from the motherboard.
Removing the battery
The battery glue is very strong, so you should use hot air again.
Never heat the battery directly and don't bend it.
The battery is glued around the outer edges but not at the center.
Apply the hot air from the display side.
We recommend running a flat tool, such as the iFlex, all around the battery.
Now take out the battery.
Be careful not to damage the battery. Take your time and heat the glue several times.
Removing the speaker
6 × 3,6 mm Phillips

Remove the screws that attach the speaker to the display and then remove it.
Removing the front camera & sensor
Camera connector

Sensor connector

Disconnect the connectors of the front camera and the sensor.
Then you can pry out the front camera and the sensor out of the chassis and then remove them.
Removing the SIM and microSD card tray
Use the SIM tool to eject the SIM card tray from your device and then remove the tray with your fingers.
Removing the motherboard
Connectors

1 × 2,9 mm Phillips

Using the spudger, carefully disconnect the marked contacts from the mainboard.
Remove the marked screw.
Now you can carefully remove the motherboard. Make sure it doesn’t get caught on the connectors you already disconnected.
The USB port is still connected to the back of the board. Once you’ve lifted the board, you can use the spudger to disconnect this contact.
Then set the board aside in a safe place.
There's a small plastic pin in the opening of the SIM tray. Make sure it doesn't fall out.
Removing the sensors
The sensor cable is also glued to the display. Carefully detach it with a flat tool. Make sure you don’t damage it.
Then you can use a pair of tweezers to remove the cable.
Removing the earpiece
The earpiece is glued to the enclosure. Carefully detach it with a flat tool like the steel spatula.
Removing the headphone output
1 × 3,5 mm Phillips

Audio connector

Unscrew the screw holding the jack in place.
Disconnect the headphone jack’s contact from the PCB. Using the spudger, carefully pry the contact out of the socket.
Remove the headphone jack from the enclosure.
Removing the USB board
3 × 3,5 mm Phillips

Remove the marked screws.
Remove the two antenna cables from their guide.
Then you can use the spudger to carefully pry out the board and remove it entirely.
Removing the vibration motor
The vibration motor is glued to the enclosure. Carefully detach the motor by inserting your tool between the enclosure and the motor.
Remove the motor.
Sometimes the adhesive layer does not stick to the vibration motor and must be removed separately. You will need it for the new display.
Preparing the new display
Protective film

In the new display’s enclosure, all the adhesive surfaces and thermal pads are covered with transparent protective film. Remove the protective film before you start with assembly.
Then take the S-Pen from the old display.

Installing the vibration motor
Put the vibration motor in the little round opening on the left side of the enclosure.
Use your fingers to press the motor firmly into place.
Installing the USB board
3 × 3,5 mm Phillips

Reinstall the USB board.
Make sure the board is flush with the enclosure.
Carefully press the antenna cables back into the appropriate guide using a blunt object such as a pair of tweezers with rounded tips.
Then fasten the screws again.

Installing the sensors
Insert the sensor cable in the corresponding recess in the upper edge of the enclosure.
Press the sensor firmly with your finger so the glue will stick again.
Installing the motherboard
1 × 2,9 mm Phillips

Connectors

Now you can put the motherboard back in.
First connect the USB board on the back of the board.
Then you can put the board back in the enclosure. Make sure no cables or connectors get stuck under the board.
Fasten the motherboard with the marked screw.
Now connect the marked contacts to the board again.
Inserting the SIM and microSD card tray
Insert the SIM card tray back into your device. Make sure the tray is positioned properly.
Installing the front camera & sensor
Put the front camera and the sensor in the opening at the upper edge of the enclosure and reconnect the connectors.
Inserting the battery
Put the battery in the enclosure. It fits perfectly into the compartment in the middle of the enclosure.
Press the battery firmly into the enclosure so the glue will stick better.
Remove excess adhesive so that the battery sits flat in the phone.
Installing the speaker
6 × 3,6 mm Phillips

Now put the speaker at the lower end of the enclosure.
Press it gently with your fingers until it clicks into place in the enclosure.
Then reinsert the marked screws.
Connecting the battery
Battery connector

Connect the battery to the motherboard. Press the contact onto the connection on the motherboard until you hear it click into place.
Installing the NFC antenna

Put the cover with the antenna back in the enclosure after hooking it onto the top of the enclosure.
Then press the cover with your fingers until it clicks gently into place all over.
Fasten the phillips screws.
Preparing the backcover
Before you put the back cover back on the case, inspect the adhesive. It should sit evenly on the edge so that the back cover can be placed flush. Remove excess glue if necessary.
Connect fingerprint sensor
Before attaching the back cover, plug in the fingerprint sensor connector.
Use a plastic tool to reach the connector.
Testing the display
Turn on your Galaxy Note 8 and test it with the integrated test mode.
Access the test mode by dialing *#0*#

In the pictures you can see the Galaxy S9. The test menu is the same for all Samsung Galaxy models.
Attaching the back cover
Put the back cover back in its original position.
Press the back cover on all over so the glue will stick.
You can also heat your device with hot air and then clamp it or weight it down with a couple books so the glue will stick better.
