If your brand new Samsung Galaxy S26 Ultra won't connect to your earbuds, car, or smartwatch, it's a frustrating roadblock. Bluetooth issues can pop up, especially with a fresh device running the latest One UI 8.5 software. The good news is you can usually fix it yourself with a few specific steps.
Let's jump straight into the most common fix. Pull down the Quick Settings panel from the top of your screen and tap the Bluetooth icon to turn it off. Wait about ten seconds, then tap it again to turn it back on. Now, try pairing your device again. This simple reset clears the immediate connection state and often works.
Restart Your Phone and the Bluetooth Device
Since the S26 Ultra is a new model, early software glitches are possible. A force restart can clear temporary bugs that might be blocking the Bluetooth radio. Press and hold the Volume Down button and the Side/Power button together for about ten seconds.
Release the buttons when you see the Samsung logo appear. Do the same for the device you're trying to connect to, whether it's headphones or a speaker. Once both are back on, attempt the pairing process from the beginning.
Forget and Re-Pair the Problem Device
If the device was paired before and now won't connect, the saved pairing information might be corrupted. Open Settings and go to Connections > Bluetooth. Find the troublesome device in your list of paired gadgets.
Tap the gear icon next to its name and select Unpair or Forget. This completely removes it from your phone's memory. Put the other device back into pairing mode, then search for it on your S26 Ultra and set it up as if it were brand new.
Clear the Bluetooth System Cache
Sometimes, the system files that help Bluetooth run can get scrambled. Clearing this cache is safe and doesn't delete your paired devices. Go to Settings > Apps. You might need to tap the three-dot menu and select Show system apps.
Scroll down and find Bluetooth in the list. Tap on it, then select Storage. Tap the Clear Cache button. After doing this, restart your phone and test the Bluetooth connection again.
If that doesn't work, you can take the more thorough step of clearing the Bluetooth data. This will forget all your paired devices, so you'll have to re-pair everything. In the same Bluetooth app storage menu, tap Clear Data instead, then confirm.
Check for a Software Update
Samsung frequently releases updates to fix bugs, especially for a flagship phone in its launch window. An outdated system can have compatibility problems with newer Bluetooth accessories. To check, open Settings and go to Software update > Download and install.
If an update is available, connect to Wi-Fi and let it install. Also, check the companion app for your Bluetooth device, like the Galaxy Wearable app for Samsung earbuds, to see if a firmware update is available for the accessory itself.
Reset Your Network Settings
This is a more comprehensive step that resets all wireless radios, including Wi-Fi and mobile networks, back to their default state. It will erase all your saved Wi-Fi passwords and paired Bluetooth devices.
Go to Settings > General management > Reset. Select Reset network settings and confirm. Your phone will reboot. Afterward, you'll need to re-pair your Bluetooth devices and reconnect to Wi-Fi networks.
Boot Into Safe Mode
If a recently downloaded third-party app is interfering with the Bluetooth stack, Safe Mode will tell you. To enter Safe Mode on the S26 Ultra, press and hold the Side/Power button until the power menu appears.
On the menu, tap and hold the Power off option. You'll get a prompt to reboot into Safe Mode. Tap it. If Bluetooth works perfectly in Safe Mode, you know a downloaded app is the cause. Restart normally and try uninstalling apps you installed just before the problem started.
Address Specific Connection Scenarios
For car Bluetooth, the process is often more finicky. I'd recommend deleting your phone from your car's infotainment system memory first, then forgetting the car on your phone. Start the pairing process fresh from the car's menu, not your phone.
With Samsung Galaxy Buds or a Galaxy Watch, always use the official Galaxy Wearable app for the initial setup and management. It handles the connection more reliably than the standard Bluetooth menu. If your phone connects to one device but not another, the issue is likely with the accessory, not your S26 Ultra.
Make sure the accessory is fully charged and in proper pairing mode, which sometimes involves holding a button for several seconds until an indicator light flashes. Keep the two devices close together during the initial pairing process, ideally within three feet.
