How to Fix Microphone Not Working On Android?

There are several easy and simple troubleshooting steps you can take to fix the Microphone not working during calls on Android. Let’s explore some possible solutions:

Testing your microphone online is an essential step in troubleshooting the problem. Luckily, several user-friendly websites allow you to check if your microphone functions correctly without much hassle.
