* Ensure that you are not connected to Bluetooth as all audio will be routed through the Bluetooth accessory.

* If you are using a ringtone that you installed yourself, try changing to a default ringtone that came with your phone.

* Make a test call through the speaker phone to see if the sound is equally low there.

Check for anything that might be covering the microphones

* Ensure that the microphones or speaker on the device are not covered.

* Ensure the protective film that ships with the device has been removed.

* If you are using a case, cover or screen protector on the device, we recommend removing and trying without it.
