- FAQs
1. Quick checks first
- Turn Bluetooth off and on from Quick Settings.
- Make sure the accessory is charged and switched on.
- Put the accessory in pairing mode. For many earbuds, this means opening the case or holding a button until a light flashes.
- Keep the phone and accessory close together, within a metre or two.
- Restart the phone.
2. Forget the device and pair again
Old pairing information is a frequent cause of problems. Open Settings > Connected devices (Samsung: Settings > Connections > Bluetooth), tap the gear icon next to the device and choose Forget or Unpair. Then tap Pair new device, put the accessory in pairing mode again and select it.
Tip: Many earbuds also have their own reset. Check the maker’s instructions, as resetting the earbuds and then re-pairing fixes many stubborn issues.
3. Problems with audio or calls
| Problem | Try this |
|---|---|
| Connected but no sound | Tap the device in Bluetooth settings and turn on Media audio |
| Calls not using earbuds | Turn on Phone calls / Call audio for the device |
| Sound is delayed in videos | Update the app and the earbuds’ companion app |
| Only one earbud works | Put both back in the case, then re-pair |
| Volume very low | Check the media volume and any absolute volume or EQ settings |
4. Connection keeps dropping
- Make sure the accessory is not connected to another phone, tablet or laptop at the same time; disconnect it there.
- Keep the phone out of back pockets and away from metal objects, which weaken the signal.
- Turn off battery limits for the accessory’s companion app, so Android does not stop it in the background.
- Update your phone’s software and the accessory’s firmware through its companion app.
5. Reset connections (last step)
If nothing works, reset your phone’s network settings. On many phones this is Settings > System > Reset options > Reset Wi-Fi, mobile & Bluetooth. This removes all Bluetooth pairings and saved Wi-Fi networks, but not your photos or apps. You will need to pair every Bluetooth device again.
Still having trouble? Start the phone in Safe Mode to check whether a downloaded app is interfering, or contact the accessory maker, as the accessory itself may be faulty.
FAQs
Why will my earbuds not show up in the list?
They are probably not in pairing mode, or they are already connected to another device. Disconnect them there and try again.
Does Bluetooth drain my battery?
Modern Bluetooth uses little power. You can turn it off when not needed, but it is not a major battery drain.
Can I connect two Bluetooth headphones at once?
Some phones support audio sharing with two devices. Check your phone’s Bluetooth or Sound settings for this option.
