Step-by-step instructions in replacing Galaxy Note 9 Loudspeaker module
You may spend several minutes in popping open the back cover of your Galaxy Note 9 and that’s the most challenging part but once you can remove it, replacing the loudspeaker module will be a lot easier.
Things you need
- Suction cup
- Small Phillips screw driver
- Prying tools
- Heat gun or hair dryer
- Note 9 loudspeaker module GH96-11796A
- 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.
- With the back cover already removed, get your screwdriver and unscrew 7 screws that hold the loudspeaker module in place. The loudspeaker module is, of course, located at the bottom part of the phone where the USB port is. Once the screws and remove, you can use a prying tool to remove it.
- Once the original loudspeaker module is removed, replace it with the new one and then secure with the screws you just removed.
- Turn on your phone and play some music tracks to check if the new loudspeaker module is working.
- Reconnect the fingerprint scanner flex cable and put the back cover on. Apply moderate heat to loosen the adhesives and set the phone to cool down.
And that’s pretty much it! Depending on your know-how in disassembling smartphones, this procedure can be very easy to do or overly complicated.
