Clean your ear speaker with fine short bristle brush and blow with compressed air and you'll be good.

Doesn't work for me, still can't hear. Have to use loudspeaker.

I'm experiencing the same issue. I think there is something internally wrong.  I spoke with tech support regarding this issue they say I will have to send my phone in for further evaluations after I tried multiple things with them via phone.  Ultimately, hard resetting the Note 8. Little upset to be experiencing this issue and only had the phone about 6 months.

I also experienced low in call volume on my note 8. What I did is I used electric toothbrush to clean the speaker at the top of the screen and it solved the problem. Now I can clearly hear properly when i have a call. I hope it helps thanks.

*Maybe the cause of my low call volume is due to the glue i used when I installed my domeglass tempered.

All I can say is Wow. 

Toothbrush trick did the job. Days of searching for a answer and on the verge of sending the phone back and it comes down to an electic toothbrush  

Thanks for making the post

[MARC0HH]

I know speaker on bottom is, where is the one for hearing 

[user7tTPhrUeqH]

Just the toothbrush? No additional chemical used?

[MARC0HH]

Yes just the tootbrush. Used it for about 3minutes or more until you see if there is some changes
