Recognizing an NFC antenna fault on the Galaxy S26 Plus

When the Galaxy S26 Plus refuses a contactless payment, no longer detects a card or an NFC tag, or no longer pairs in one tap with a speaker or headset, the NFC antenna is often the cause. This thin component, glued against the back of the chassis, transmits the short-range signal used by Samsung Pay, Samsung Wallet and quick pairing.

A fall, an impact on the back of the device or a previous repair that was not closed properly is enough to detach or break the antenna's flex cable, even when the screen and battery are working normally.

Service Pack NFC antenna: what this means

The Quality line on this listing states Service Pack: this is a genuine manufacturer part, supplied as a Service Pack, meaning in Samsung's own repair packaging. Nothing has been repaired or reglued on it: the part comes new from the same production line as those fitted during assembly.

This packaging carries a reference number that the repairer can compare directly with that of the old antenna before ordering: GH97-31594A.

Compatible with which Galaxy S26 Plus?

This NFC antenna is intended for the Galaxy S26 Plus. It is designed for this specific model, with no cross-compatibility stated with any other device.

Fitting the NFC antenna: precautions

Replacement requires opening the back of the phone and handling a thin flex cable, which is glued and sometimes located close to other components. Suitable opening tools and measured heating reduce the risk of tearing the flex cable or damaging neighbouring parts.

Before closing the device, an NFC detection test (card, tag, quick pairing) confirms proper contact of the flex cable and avoids having to reopen the device a second time.
