What is causing my mic to not work during phone calls, and how do I fix it?

I have a ZTE Blade Spark, and for the first few months of having it, it worked well. Now whenever I'm in a call the other person cannot hear me. The mic works fine when I'm using text to speech, or using voice commands for Google. When I try to record a video on Snapchat the audio starts out scratchy but gets better. This happened to another ZTE phone I had previously as well.
