Galaxy A30 Bottom Microphone stopped working

[A30Man]

Hello

I just realized my phone recording became mono and only Head Microphone is working.

I think it happened after I updated my phone.

It doesn't seem like a hardware issue , because when I'm recording with a stereo recorder , one side is not muted its only mono with head microphone sound.

It's happening in camera too , sound is mono.

Can it be hardware issue ? What should I do?

Edit 1 :

I tried a mic testing app and heres result

As you can see in stereo mode it's using top (left) mic for both channels 

I'm so confused 😞

Try the tests via Hardware test: 

go over to your dial pad and type in *#0*#, this will bring up a number of tests.

If all.else fails can you get to a Samsung Experience Store or Samsung Service Centre.
