I also have whats app mic issues.... It works fine sometimes and people can hear me on WhatsApp call... Then randomly during the day it will fail and I can hear the other person and they can't hear me. Sometimes the phone evens says there is a mic issue and suggests to restart. Samsung... Please fix this bug. I can't keep restarting my phone to get whatapp calling to work.
Hi standard stock phone app and calling works 100 % all the time, sound both directions . However sometimes on WhatsApp calling, I can hear the other end, but they can't hear me. But there are times where it works fine. So clearly intermittent issue and I don't know what triggers it to stop working. Yet if switching back to a normal phone call the mic will work and people can hear me . lThe only way I figured out was to restart the phone and then it works again on WhatsApp
