- Ensure the Bluetooth device isn’t connected to another device. Try forgetting the device and reconnecting to it.
- You can also try updating the firmware or resetting the Bluetooth device to fix the issue.
- If nothing works, try resetting the network settings on your Android device.
Basic Fixes
- Use 5GHz Wi-Fi : Bluetooth uses a 2.4GHz frequency band, which can overlap the signals and cause problems. Therefore, use a 5Ghz Wi-Fi.
- Disconnect other devices: Not all Bluetooth devices can connect to multiple devices at once. So, if your Bluetooth device is not connecting to your phone, it may have already connected to another device.
- Restart devices: Restart both your smartphone and the Bluetooth device to fix any bugs and glitches.
Fix 1: Forget Device
If you’ve previously paired and used the Bluetooth device, but it suddenly refuses to connect to your smartphone after some time, forgetting the device, and attempting to reconnect might help.
Open the Settings app > go to Bluetooth > select the settings icon next to your Bluetooth device > select Forget .
Fix 2: Update or Reset Bluetooth Device
Some Bluetooth devices come with a dedicated app for controlling and configuring them. These apps also offer the option to update the firmware.
Resetting the Bluetooth device will reset all the applied configurations to default, which means that most issues will likely be fixed. This is also possible on the official Bluetooth device app. Here’s how it looks on the Samsung Galaxy Buds app.

Fix 3: Reset Network Settings
