Android Bluetooth issues are usually caused by pairing errors, outdated software, or interference. Most problems can be fixed by restarting Bluetooth, forgetting the device, updating Android, or resetting network settings. If Bluetooth still won’t connect, check device compatibility or hardware issues.

After clearing, restart your phone and try pairing again.
Some Bluetooth devices may not support your phone’s Bluetooth version. For example, older Bluetooth speakers may not work with newer Android phones.
