ANote 20 Ultra mic issue.. Need help

[atingarg]

Hello all
My note 20 Ultra mic suddenly stopped working for apps, voice recorder records blank. No audio
Unable to search on any voice search option on any app. Voice search keeps on listening but not detecting any voice

But MIC working fine on Cellular calls, video recording in camera

Strange thing noticed.. Mic works on Cellular calls but not in Whatsap calls.
How is this possible?

I have reset all settings, still same.
Checked all permission of mic.. No issue
