Microphone muted in all calls

[JuliaSays]

Help please! On all calls that I try to make/receive the microphone is muted. I have tried checking all settings but cannot get this to unmute. Does anyone know what may be causing this?

Hi @JuliaSays 

I'd suggest to first try Safe Mode  > 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. 

This is a Samsung Support Page > Why-i-cant-hear-anything-when-making-calls. 

And you could ckear the phone's System Partition Cache Files > Clear Cache Files from the phone's System Partition Section  > https://www.samsung.com/uk/support/mobile-devices/how-do-i-clear-the-cache-on-my-device/ You may need to insert your earphones or hook upto a powered On Laptop to access the Clear Partition Section. This may help with lag or stutters as this clears the phone of old/unused or broken cache files.There is also a Repair Apps option in the Menu System too.

If I can be of any further help then please don't hesitate. Take care.  😎
