Method 1: Toggle Bluetooth and restart the Galaxy S25

A quick reset often restores Bluetooth services after an update.

1. Turn Bluetooth off for 15 seconds.
2. Restart the phone.
3. Turn Bluetooth back on and try pairing again.

Method 2: Forget the accessory and pair it again

Saved Bluetooth records can become invalid after a firmware change.

1. Open Settings > Connections > Bluetooth.
2. Tap the gear icon beside the device and choose Unpair.
3. Put the accessory back in pairing mode and reconnect.

Method 3: Make sure the accessory is not already connected elsewhere

Many earbuds, speakers, and car systems refuse a second connection.

1. Turn Bluetooth off on nearby phones, tablets, and laptops.
2. Reset the accessory if needed.
3. Try pairing only with the Galaxy S25.

Method 4: Reset network settings

This can clear a broken Bluetooth stack without erasing personal files.

1. Go to Settings > General management > Reset.
2. Tap Reset network settings.
3. Pair the accessory again after the restart.

Method 5: Update the accessory firmware and Galaxy software

Bluetooth fixes sometimes arrive from both Samsung and the accessory maker.

1. Check the companion app for firmware updates.
2. Open Settings > Software update on the phone.
3. Install any available updates and retest.

Method 6: Test another Bluetooth device

This shows whether the issue is with the phone or one accessory.

1. Try pairing a different headset, speaker, or watch.
2. If only one device fails, reset or update that accessory.
3. If all devices fail, the phone needs deeper troubleshooting.

Method 7: Use Safe Mode to check for app conflicts

Third-party audio, automation, or companion apps can break Bluetooth behavior after an update.

1. Boot the Galaxy S25 into Safe Mode.
2. Test Bluetooth before opening other apps.
3. If it works there, remove or update recently installed apps.
