Why can't callers hear me on my HTC One M8?

[AC Question]

Caller can't hear me htc 0ne m8

When i call or recieve a call the caller can not hear me when i answer, i can hear them loud and clear but the only way they can hear me is if i put speakerphone on. I played with the mute and speakerphone and it didn't help the only way they hear me is when i use the speakerphone.

Hi, have you recently dropped or got your phone wet, so much so that it could have damaged the mic? also could there be some dust covering the mic?
