When calling, there may be instances where the audio quality is poor or there is no sound at all. Poor audio quality during a call could be affected by poor network coverage or structural obstructions. This problem could also be due to a software issue. 

To solve this issue, follow the steps below:

Note: Before proceeding to the troubleshooting steps, be sure that the Razer Phone is up to date. Navigate to Settings > System > Advanced > System update >  Check for update.

  1. Check the network coverage in your area. Poor network coverage will normally affect the quality of your calls and can even result in dropping calls.
  2. Remove any cellphone covers, case protectors and screen protectors from the phone as they may be obstructing the sound from the phone speakers.
  3. If the phone has a good network coverage and all obstructions from the phone have been removed and you are still experiencing issues, restart the phone by pressing and holding the power or fingerprint button.
  4. Test the phone again.
  5. If the issue persists, make sure that the audio settings are correct and the device is not muted.
  6. From your “Top menu”, click the “Settings” icon indicated by a cog.

  7. Select the “Sound” settings. Ensure the “Call volume” is set to its maximum for testing. You can adjust the volume to your liking after testing.

  8. Test your phone again.
  9. After all the settings have been configured, call your Razer Phone from a different phone line.
  10. Reboot the device and test the phone again.
  11. If the issue persists, back up your phone data and perform a factory reset.
