Please someone give any type of solution in details. The on call mic volume killing me. I have to put the earphone mic fully on my lip for the other person to hear me!

I used app from play store to check and I guessed it right, while mic mode was on 'Direct' and I recorded from usual earohone mic distance, then the sound was, loud and clear. But when I recorded in the same condition in the mode 'Communication', then I barely can hear me. Now after this test, I am sure the problem is in the feature 'microphone noice cancellation' for calls only. So as I identified the issue, is it impossible to fix? Can I totally disable the function 'noice cancellation' on my device? Please help. I am in desperate need of a fix during this covid pandemic as many many important meetings are happening online.

Mic is loud enough on the general phone call app though!!!
But very low on any online call like messenger call / whatsapp call / discord call / google meet call / zoom call. But if I record on messenger or whatsapp, it sounds alright. I repeat, recorded general sound is OKAY but not when on call on any app other than general phone call app. Tested same earphone on same apps from an old samsung phone too. No problem found there at all! Sounded clear while using samsung during messenger call / whatsapp call / discord call / google meet call / zoom call. So don’t say it's mic's fault. It isn’t. It is software handling problem as far as I can understand. Please show me a way fast.

Hi fakhrulsojib
Thank you for your asking. I tested Messenger/WhatsApp Call with phone mic and earphones mic in the same version, yet I didn't encounter the same situation. Kindly try some stay-at-home troubleshooting tips below:
1. Please try to enter "Safe Mode". If the Messenger works well in Safe Mode yet the issue remains out of Safe Mode, please check on any disturbance from the installed 3rd party apps.

Same case here. Mic volume is very low when using Messenger call, but it's okay when using the native phone call app. It's frustrating.
