I also had this small update but my Mic is working fine - Do you have any 3rd party apps that could be causing this?

I would also consider performing a system repair (But backup all your file before hand)

Hi and welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines.

I would suggest that you try to boot your phone into safe mode to see if the problem may be related to any 3rd party app that you have installed in your phone:

You can try to reinstall/repair the latest software using PC Companion:

In PC Companion, press start on Support Zone > Start on Update the phone/tablet software > click on the blue highlight (Repair my phone/tablet). Do this without the phone connected. Follow the instructions on screen to perform the repair.

Before repairing the software in your device you may want to backup your information first. Check out this topic for more information on how to:
