Have you tried clearing the Partition Cache Could be an app or Theme issue affecting the phone.
Might be worth clearing the Partition Cache on the phone
It's a quick simple process that can help a lot
Wiping cache partition fixes some of the bugs and improve performance by removing unwanted cache files.
Turn off your phone.
Connect your phone with a USB cable to PC or another Samsung mobile
You will see the charging icon on your screen. Wait till it shows charging with battery percentage.
Next, press and hold the Volume up and Side key simultaneously. You can press the volume up button just before the Side key. The Samsung Logo followed by Samsung Galaxy appears on the screen.
At this point, release the keys Phone will boot into Android Recovery mode
In Android recovery mode, using Volume keys, choose "Wipe Cache Partition" .
Then press Side Key to Confirm by selecting "Yes" and then press Side Key
You get "cache wipe complete" at the bottom of the screen Restart the phone to complete the process
@Lelly73 Just checking if you have run the interactive checks via Samsung Members-support Diagnostics -Microphone? If fault would need to contact support.
if that shows up ok try wiping the cache partition as @Glenntech suggested, also an idea to Repair apps via the same Recovery Menu.
I do not work for Samsung or make Samsung Products but provide independent advice and valuable contributions.
Hi Glenn and James. I did as suggested and wiped the Cache as advised . Then tried the diagnostics and the microphone is still not working. It looks like I will have to send it in for repair 😔 not the best time of year to be without a phone. Thank you both for your help
Double check that nothing is blocking the microphone holes Otherwise its unfortunately a trip to Samsung approved repairs If you have a Samsung Experience Store near you, it's worth popping in to see if they can look at it.
