Galaxy Note 8: Why the sound is not heard clearly with crackling and is broken irregularly and the volume is low during call on the device?

Last Update date : 2017.12.14

If receiving sound during call is not heard clearly or broken irregularly, firstly please check whether
you attach Samsung-unapproved 
protect accessories covering perfectly all parts on Galaxy Note8
device’s back.

 

Air Path is placed on up and down part of rear camera 

 

Some of Samsung-unapproved protect accessories like films, covers, vinyl which attach on device
back
side cover even Camera, Flash, HRM sensor and this causes to block the Air Path(Air vent hole)
inside
the device. Due to blocking of Air Path(Air vent hole), receiving sound is not heard clearly
or broken i
rregularly, and volume may be also low.

Please keep in mind not to use Samsung-unapproved protect accessories covering Camera, Flash,
HRM sensor.

Especially, as this symptom can also appear when protect vinyl or film cover on a little bit of Camera
Deco, be
careful that the protective vinyl or film does not cover on any parts of the Camera Deco.

 

 

Be careful that the protective vinyl or film does not cover on parts of the Camera Deco where Air Path is placed

 

 

Additionally, please check whether or not protect film covers Mic. hole if call volume is low/muted
or Mic. Audio quality is poor.

 

 

Be careful that protect film does not cover Mic hole  

 

 

 

Also, if the device has been immersed in water or speaker is wet, sound may not be heard clearly
during a call because water may get in the speaker hole during exposure underwater.

If upper phenomenon happens or the device gets wet after getting out the water, firstly please wipe
device smoothly
with a dry, soft cloth and keep putting during certain period of time to dry it
thoroughly before using device.

Additionally for faster drying of water from speaker, it will help that you hold the device while speaker
of device is
facing down and shake device smoothly a few times to remove remaining water.

Despite this, when some moisture remains on Mesh in front speaker, sound may not be still heard
clearly.

At this time, as this moisture can be also removed by speaker vibration during call, please check
the device’s sound state
while making call for a period of time.

If you are still having trouble with the sound after trying these tips, please visit any
Samsung Service
Centre with device.
