Follow these troubleshooting tips to overcome bluetooth issues.

  1. Is bluetooth switched ON? I often switch off bluetooth to save battery and forget to switch it on when needed.
  2. Restart device: Restarting a device solves the problem many times.
  3. Is there a specific pairing process? Accessories like headphones need to be put in pairing mode to work. Refer to the device's user manual for the pairing process. Some devices require touching the phone to the device. Some require you to enter a code or pressing down a button.
  4. Safe mode: Sometimes, 3rd party apps could be interfering with Bluetooth. Restart the phone in safe mode. Learn to restart an Android in safe mode. Safe mode disables all 3rd party apps. If Bluetooth works in safe mode, it is safe to assume that some app is interfering with it. If that is the case, restart normally and disable apps one after another to zero in on the culprit.
  5. Factory reset your phone: Don't do this before you have tried all other steps. Learn how to factory reset an Android .
  6. Distance between the two gadgets: Bluetooth works the best upto 10 meters. High end devices may have a range upto 100 meters.
  7. Interference: Gadgets like WiFi routers, USB 3.0 ports and previously paired devices can interfere with bluetooth connections.
  8. Delete the device and pair again: If the device pairs but does not transfer data, unpair the device and pair it again.
  9. Unpair all devices: If there are too many devices paired, unpair all devices and pair them once again. This time pair only those that you really require.
  10. Check profile compatibility: For example, some Bluetooth headsets can be used to remote control the playback. The A2DP Bluetooth profile allows transfer of audio from the audio device to the headphone. But to send remote control instructions from the headphone to your audio system, AVRCP Bluetooth profile is used. So, to use your headset as a remote control, your audio system must support A2DP as well as AVRCP Bluetooth profiles. See this Wikipedia page for a list of Bluetooth profiles.
  11. 'Bluetooth Smart' compatibility: Bluetooth Smart (Bluetooth Low Energy) devices cannot connect to devices that support only Bluetooth Classic. So, if a device uses Bluetooth Smart, make sure the other device also supports Bluetooth Smart.
  12. Battery saving mode: Bluetooth may get disabled if your phone is on battery saving mode. Either charge the battery or allow Bluetooth to work in battery saving mode. To see how to use battery saving mode in Android, click here.
