Question:Q:My microphone works in WhatsApp call but on a normal phone call people barely hear me? How can I fix this?

Recently, after updating to iOS14.3, I’m facing issues on normal phone calls. People of other side cannot hear me and says volume is too low. When I place my hand near to mix piece, sound gets better. But there is no issue on WhatsApp call. I tried this on different locations to see if it’s a network issue but it’s not.

Please help.
