Title
Samsung Galaxy S21 Ultra NFC Antenna & Charging Coil Replacement
Introduction
Use this guide to replace a damaged NFC antenna, charging coil assembly, and loudspeaker on your Samsung Galaxy S21 Ultra.
This guide was performed on the ***SM-G998B/DS*** (international) model. Other models have an additional antenna cable sitting in the edge of the midframe.
If you do not replace the adhesive seals when reassembling, your device will function normally, but will most likely lose its water protection.
You’ll need replacement adhesive to reattach components when reassembling the device.
Conclusion
If possible, turn on your device and test your repair before installing new adhesive and resealing.
Compare your new replacement part to the original part—you may need to transfer remaining components or remove adhesive backings from the new part before installing.
***To reassemble your device, follow these instructions in reverse order.***
Take your e-waste to an [[E-Waste|R2 or e-Stewards certified recycler|new_window=true]].
