NFC, or Near Field Communication, allows your Galaxy S25 Ultra to make contactless payments, pair devices instantly, and share files with just a tap. When it stops working, it can be frustrating, especially if you use it for Samsung Pay or quick Bluetooth connections.
If your Galaxy S25 Ultra’s NFC isn’t responding, there are several reasons this might happen, from simple settings errors to temporary software glitches. Here’s how to fix it.
Why Your Galaxy S25 Ultra NFC Might Not Be Working
- NFC is turned off in settings.
- The device case or accessory blocks the NFC antenna.
- Outdated software or minor system glitches.
- Conflicts with payment or third-party apps.
- Damaged NFC area or hardware issue.
Make Sure NFC Is Enabled.
Your phone’s NFC feature may have been accidentally turned off. Enabling it ensures your device can detect nearby NFC tags, payment terminals, or other phones.
- Open Settings, and then tap Connections.
- Tap NFC and contactless payments, and then toggle on NFC.
Try tapping your phone against another NFC-enabled device or payment reader to confirm it works.
Check the NFC Detection Area.
NFC only works when the antennas of two devices are close. On the Galaxy S25 Ultra, the NFC antenna is located near the top center of the back panel.
Remove any thick case, magnetic holder, or metal accessory that could block the antenna. Then, try again by aligning the NFC area properly when tapping your phone.
Restart Your Phone.
A simple restart often clears out temporary software errors that can affect NFC functions.
- Swipe down from the top-right corner to open the Quick Settings panel.
- Tap the Power icon, and then tap Restart.
After rebooting, test NFC again by opening Samsung Pay or tapping another NFC device.
Clear Cache of Payment Apps.
If you primarily use NFC for contactless payments, cached data from Samsung Pay or Google Wallet might be causing the problem. Clearing it can help refresh the app.
- Open Settings, and then tap Apps.
- Tap Samsung Pay or Google Wallet, and then tap Storage. Tap Clear cache, and then reopen the app.
Try making a contactless payment again to see if NFC works.
Update Software.
Outdated software can create compatibility problems between your phone and NFC devices. Keeping your Galaxy S25 Ultra updated ensures smooth operation.
- Open Settings, and then tap Software update.
- Tap Download and install, and then follow the prompts if an update is available.
Once the update is complete, restart your phone and test NFC.
Reset All Settings.
If nothing else works, resetting all settings can fix configuration issues without erasing your personal files.
- Open Settings, and then tap General management.
- Tap Reset, and then tap Reset all settings.
Your phone will restart automatically. Afterward, re-enable NFC and test if it functions properly.
Fixing NFC on your Galaxy S25 Ultra is usually quick once you check the basics. Most of the time, it’s a settings issue, an outdated system, or a blocked antenna.
