Introduction
Use this guide to replace a damaged NFC antenna and charging coil assembly 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.
