Galaxy A 53 mic stopped working

[The-Chef]

I had bought a Galaxy A 53 and microphone was working then all of a sudden it stopped.   I have factory reset the phone did all the trouble shooting that has been offered in the community. When connected to bluetooth I can everyone talk they still cant hear me. Any one any ideas how to fix this issue? Hard to run a buisness without taking calls

Hello 👋 @The-Chef and may I extend a Warm Welcome to the Samsung Community Forum. 

Try a forced reboot by holding down the volume down key and power button simultaneously for more than 7 seconds to restart it. When your phone resets, you will feel it vibrate.

There is also a diagnostic test tool 🔧 found in the Samsung Members App to see if that highlights anything. 

Also Safe Mode  > https://www.samsung.com/uk/support/mobile-devices/how-to-start-my-galaxy-device-in-safe-mode/ turns off downloaded apps and themes etc which may highlight an app or theme that's causing conflict. Alternatively long press the power off button and then long hold on Turn Off to get to Safe Mode. 

If your phone is within the cooling off period then consider having the phone swapped out. 

If you perform a forum search you may find existing threads with some further help or guidence within.  

If i can be of any further help please don't hesitate to ask  😎
