Hi all.. Other people I talk to are saying my voice is muffled and quiet . The problem only occurs when I talk when the phone is to my ear. Speakerphone is fine and people can hear me no issues . It's just been a problem for the last few days. If I leave myself a voicemail to test, it sounds terrible. Any ideas please?

I take it that you have tried the obvious reasons for this by using a soft nozzle on your vacuum cleaner and sucking all the debris from the small openings slots etc on the bottom edge of your phone ?

I am using microphones there and the device looks very comfortable to me I don't know what type of issue you are facing here.

@Motty2012: If you have a case or cover on the phone, please try removing it to see if this helps. If not, or if this isn't applicable, then head to the Samsung Members app > Press and hold on the app icon > Diagnostics > Mic, and follow the on screen instructions. Are you able to hear yourself clearly in the playback? Similarly, head over to your dial pad and type in *#0283#, then select “Start: RCV_1stMic” and speak into your phone like you’re on a call. Can you hear yourself talk?

Hi Andrew thanks for the reply. I've done all the diagnostics and it's muffled on Mic 1. I've booked a service call now.. They are planning to replace the charging port. Do you know if this is right? My understanding is the bottom Mic is on the same board.
