Fix #1: Restart the phone and the Bluetooth accessory

A restart clears temporary connection bugs that often appear after a firmware update. Power off your Galaxy S25 completely, wait a few seconds, and then turn it back on. Restart your earbuds, speaker, watch, or car infotainment system too.

Fix #2: Turn Bluetooth off and back on

Open Settings > Connections > Bluetooth, turn Bluetooth off, wait around 10 seconds, and turn it back on. This refreshes the local radio session and can stop repeated disconnects.

Fix #3: Forget the device and pair it again

Tap the gear icon beside the problem accessory, choose Unpair or Forget, and then pair it again from scratch. This is one of the best fixes if the update changed saved Bluetooth profiles or permissions.

Fix #4: Check for accessory firmware updates

Many Bluetooth issues are caused by the accessory, not the phone. If you use Galaxy Buds, a smartwatch, or another smart accessory, open its companion app and install any available firmware update before testing again.

Fix #5: Reset network settings

Go to Settings > General management > Reset > Reset network settings. This removes saved Wi-Fi, Bluetooth, and mobile network settings, so you will need to reconnect afterward. It is especially helpful when the update corrupted wireless settings.

Fix #6: Disable battery restrictions for the Bluetooth app or companion app

Samsung battery optimization can interrupt background Bluetooth services. Go to Settings > Apps, open the companion app you use, tap Battery, and set it to Unrestricted if available. Do the same for apps that manage your earbuds, watch, or car connection.

Fix #7: Boot into Safe Mode

If the issue started after installing a third-party app, Safe Mode can confirm it. In Safe Mode, only system apps run. If Bluetooth becomes stable there, remove recently installed apps, cleaners, battery savers, or connection managers.

Fix #8: Install the latest software update

Samsung often pushes a follow-up patch for bugs discovered after a major update. Go to Settings > Software update > Download and install and install anything available.

Fix #9: Wipe the cache partition

If the disconnects started immediately after an update, clearing the system cache can help. Boot into Recovery Mode and choose Wipe cache partition. This does not delete your personal files.

Fix #10: Reset all settings or factory reset as a last resort

If Bluetooth still keeps disconnecting, try Reset all settings first. If nothing works, back up your data and perform a factory reset. Persistent issues after a clean setup may point to a bug that needs a Samsung patch or a hardware problem with the accessory.

Final thoughts

A Galaxy S25 Bluetooth keeps disconnecting after update issue is usually caused by corrupted wireless settings, accessory firmware conflicts, or a post-update software bug. In most cases, re-pairing the accessory and resetting network settings will fix it. If you need more help, browse the Galaxy S25 troubleshooting hub for more exact-match fixes.
