Assuming you want to do it yourself, then continue reading as I will guide you through in opening your phone and finally removing and replacing the wireless charger pad or coil.

How to remove the back cover
This is the most challenging part if you’re opening up a phone with IP68 certification. It’s difficult but not impossible. You just need to be careful so as not to damage other parts inside.
- 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.
- Now place the suction cup at the bottom part of the back cover.
- 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.
After successfully removing the back cover, the NFC/wireless charging coils will now be exposed.
How to remove and replace the wireless coil NFC module
At this point, everything will be easier…
- Remove the 15 screws that secure the NFC, wireless charging coil and the loudspeaker module.
- Remove the NFC and wireless charging module and the loudspeaker module.
- Now, put in the new wireless charging module and secure it with the 15 screws you removed a while ago.
- Reconnect the flex cable of the fingerprint sensor to the motherboard.
- If you have the OEM Back Cover Sticker for galaxy s9 wireless charging, then remove the old adhesive from the back cover and use the new one instead. If you don’t, then just use the old one. It will hold the back cover in place but you have to apply enough heat to loosen it before putting it back in place.
