[lucy-]

Hy i tried calling on WhatsApp but the other person can't here my voice. I tried using Instagram and problem remains same. However on normal phone calls i am havin no issue. My internet speed is around 600Mbps. I have also checked for microphone access on the phone. 

I am using Samsung galaxy M53 5g and i think the problem occured after i updated to one ui 6
