How to tell when the NFC antenna needs replacing

The NFC antenna in the Samsung Galaxy S23 Ultra handles contactless payments, file sharing between devices, and reading digital tags. A faulty antenna shows itself through the inability to use mobile payment even with correct network connection, or systematic refusal to read NFC tags. If other radio functions work normally (WiFi, Bluetooth, 4G), the problem comes from this component.

NFC Antenna Service Pack for Galaxy S23 Ultra

This original manufacturer NFC antenna comes in Samsung Service Pack, the manufacturer's official repair packaging. New part, never assembled or disassembled, it comes directly from Samsung and carries the manufacturer reference GH42-06952A. It restores NFC features to factory condition.

Compatible only with Galaxy S23 Ultra

This antenna fits the Galaxy S23 Ultra only. Nearby models, S23 Plus or S23, use different references. Before ordering, check your device for the exact model: the antenna sits under the battery, identifiable during disassembly or via the device's system settings.

Installation and precautions

Replacing the NFC antenna requires access to the battery and logic board of the phone. Work must be done cold, away from any electrostatic source: an antistatic wrist strap prevents damage to sensitive components. The ribbon connects via a small fragile connector that supports only a limited number of connections. Reattach the antenna to its original position with quality thermal adhesive to ensure thermal contact with the chassis.

Warranty on this part

This Service Pack antenna benefits from a 2-year warranty with the shop. It covers manufacturing defects and malfunctions under normal conditions of use. Damage from incorrect installation or thermal damage is not covered.
