Removing Galaxy Note 9 Back Cover
This is where you will spend most of your time since the back cover is the phone’s primary protection. Since the Galaxy Note 9 is a notchless phone, you can expect that the back cover is properly secured with adhesive in which you have to deal with. Proceed with caution when opening your phone as you may damage other parts…
- Remove the SIM/SD card tray and pull the stylus out.
- Using the heat gun, heat up the edges of the back cover until it would be uncomfortable to touch it. Just apply enough heat to loosen the adhesive and remember that applying too much heat may damage the battery. And when applying heat, do not point the gun in one place, always move around the edges.
- Once the cover is hot enough, put the suction cup on the lower part of the phone or where the USB port is.
- Gently lift the suction cup until you can see a slight opening between the back cover and the frame. After applying reasonable amount of upwards pressure, the back cover should separate slightly from the frame but if it doesn’t, you may need to apply more heat.
- Place a prying tool into the crack to prevent the glue from sticking back to the frame.
- Once the prying tool is inserted, you may now remove the suction cup.
- Move the prying tool along the sides to loosen the adhesive but be very gentle in doing this so as not to mess up some components. Also, don’t push the prying tool too deep. You may use more prying tools if necessary. If the phone cools down before the back cover is removed, try applying heat again to loosen up the adhesives.
- Once the back cover is loose enough, lift it gently so as not to break the flex cable of the fingerprint scanner. Remove the flex cable to set the back cover free.
Removing Galaxy Note 9’s Motherboard
Once the back cover is removed, the next thing that should come off so that you will have access to the rear cameras is the motherboard. Here’s how you remove it…
- Remove the screws that secure the top protected frame as well as the wireless charger pad. There are about 11 screws so carefully unscrew them one by one.
- Disconnect the battery’s flex cable from the motherboard so you don’t have to worry about anything shorting out.
- Remove the screws that hold in place the bottom frame or the speaker module. There are about 7 screws you have to remove.
- Carefully remove all the flex cables or ribbons that are connected to the motherboard including the flex cable of the charging port.
- Remove the 3 screws that attach the motherboard on the frame.
- Once you’re sure every connection to it is removed, you may now gently pull the Motherboard out of your phone.
Removing and replacing the rear cameras
Your Galaxy Note 9 has two cameras at the back but both are integrated into one module. You couldn’t possibly replace just one of them because they’re not sold separately. Now, here’s what you’re going to do to remove and replace it…
- Turn the motherboard over to view the backside of it.
- Disconnect its connector from the mobo using a plastic prying tool.
- Once the connector is removed, you can just pull the camera module from the motherboard it’s secured with an adhesive. You shouldn’t have issues removing it now.
- Once the old and defective camera module is removed, replace it with the new one. You must use a double-sided tape for it to stick to the motherboard.
- Connect the new camera module to its connector on the board.
- Now, place the motherboard back and then secure it with screws.
- Reconnect all other flex cables you disconnected a while ago and make sure all screws are in place.
- Replace all the components you removed and make sure they’re properly mounted and then reconnect the battery.
- Even without the back cover, your Galaxy Note 9 should be able to turn on and work normally so you should try that to test if the new camera is working.
- If everything works properly, then reconnect the flex cable of the fingerprint sensor and then replace the back cover.
