It is an IOS 14 Microphone BUG ISSUE not a Hardware ISSUE, proven and TESTED !!!

Update Iphone 7 to IOS 14.4, Microphone is used by another applicarion Error, i also update my Iphone 5(SE) to ios 14.4, this one no issue at all.

APPLE don't tell me its hardware issue, cause i know it isn't, i tested severall times, the problem is your security patch wich not allowing application top accces mic without user permission, because there is a bug in it, that randomly prevent application (Phone, Camera) accessing the mic.

After some tweaking i finally concluded that IT IS IOS an 14 BUG !

How DO I KNOW THIS?

because after i reset all data and setting mic is working. but then after several apps install (WHATSAPP etc) mic doesnt work again.

DO THIS : Each time your mic or speaker doesn't work, try to go to SETTING, ACCESSIBILITY, VOICE CONTROL. Turn VOICE CONTROL to ON, wait for a few second, then it will prompt on top of your screen "microphone is being used by another application, voice control will be turn off".

After you "reset all setting", then microphone will work again.

Or RESET ALL DATA and SETTING (FACTORY RESET = means you lose all your data on phone)

whenever microphone is working, you can activate "voice control".

when mic is not working, try turning on "voice control", then you will get "microphone is being used by another application" error (Which is impossible because i already close all other application).

IT IS DEFINITELY an IOS 14 BUG !!

APPLE , PLEASE BE A GOOD CORPORATE AND FIX THIS FFS !!
