Replace the earpiece speaker in your Samsung Galaxy Note9 using these steps:
Remove the SIM card tray.
The SIM card may fall out of the tray easily.
Power off your phone before starting disassembly.
Apply a suction handle to the back cover.
If the glass is badly cracked, cover it in packing tape to create a surface for the suction cup to adhere to.
Apply more heat if the adhesive won't budge; avoid excessive force as it could break the glass.
Apply even heating when dealing with stubborn adhesives — do not use excessive force.
Begin at the center of the device and use an opening pick to carefully cut the adhesive along the right side.
Be extremely cautious near the weak glass area.
Apply heat to the left side of the rear panel using a heat gun, hair dryer, or iOpener for 3 minutes.
Careful handling is required around corners, as glass is most fragile there.
Insert an iSclae into the upper-left corner of the rear panel.
Use an iOpener, hair dryer, or heat gun to apply extra heat as needed to aid in adhesive removal.
Separate the right side of the rear cover first.
Use the tip of a spudger to carefully lift the fingerprint sensor ribbon cable from its socket.
Remove the back cover.
Test phone functionality before reapplying adhesive and resealing the phone.
Remove the upper midframe by unscrewing the nine 4 mm screws using a Phillips screwdriver.
The upper midframe may snap into and out of place during removal.
Peel the wireless charging coil off the battery, starting from the left side.
The adhesive is weak; use an opening pick to cut it if necessary.
Disconnect the orange ribbon cable from the motherboard using the tip of a spudger.
Remove nine 4 mm Phillips screws from the plastic cover next to the battery.
Remove plastic cover adjacent to the battery.
Insert the spudger tip into the top of the lower midframe.
Remove the front camera using tweezers.
Be careful not to damage the front camera connector when removing.
Insert the flat end of a spudger into the front sensor connector's socket and gently pry it loose.
Disconnect the display cable using the flat end of a spudger.
Disconnect the touchscreen cable from the motherboard using the flat end of a spudger.
Disconnect the charging assembly from the motherboard using the flat end of a spudger.
Locate the motherboard on the device.
Locate the upper-left corner of the motherboard and use a spudger to gently lift it.
Do not pull on the motherboard if snagged; instead, carefully reposition the cable.
Insert the angled tweezers into the gap in the side of the phone's earpiece speaker slot, using only the tip.
Be careful not to damage the earpiece speaker.
