Galaxy Note 9 - Replacing the screen

1. Turn off your device by holding down the power button until the “Power off” option appears.
2. Use your finger to confirm that you want to shut down your Galaxy Note 9 and wait until the screen goes blank.

1. 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.
2. 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.

1. 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.

1. 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.
2. Then heat the next part and insert the picks one by one.

The back cover glue is extra strong on the lower edge.

1. 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

1. After detaching the back cover, carefully lift it and disconnect the fingerprint sensor using the spudger.
2. Then you can completely remove the back cover and set it aside.

• 11 × 4,0 mm Phillips

1. Remove the screws that attach the upper cover to the display.
2. 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.
3. Now remove the antenna.

• Battery connector

1. Using the spudger, carefully disconnect the battery contact from the motherboard.

Always lever from a side where there are no small components on the motherboard. This avoids unintentional damage to capacitors or ICs.

The battery glue is very strong, so you should use hot air again. The battery is glued around the outer edges but not at the center.

Never heat the battery directly and don't bend it.

Watch the video (playbutton in the upper right corner of the first picture) to see the release of the battery.

1. Apply the hot air from the display side.
2. We recommend running a flat tool, such as the iFlex, all around the battery.
3. If the iPlastix is not strong enough, you can also use a wide battery spudger.
4. Slide a flat tool under the battery to gradually loosen the adhesive. Do not push the tool too far in, otherwise you could damage the display from below.
5. Lift up the battery and remove it from the device.

Before removing the vibration motor, check your spare part. It is possible that an vibration motor is already installed there. Then you can skip this step.

1. The vibration motor is glued to the enclosure. Carefully detach the motor by inserting your tool between the enclosure and the motor.
2. 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.

1. 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.
