I have the ZTE Prestige and it seems like people cant hear me when i make a call

[AC Question]

Make a call and some people can hear me and others cant. i already went to the store that i bought it from and it worked but now its doing it again. But this only happens on some calls.

Welcome to Android Central! Does that happen on speakerphone or wired/Bluetooth headset? If not, then you can narrow the problem to the primary phone mic. Make sure you're not blocking the mic opening by accident (like with your finger, or with a case). Also make sure the opening isn't clogged with lint or other gunk.
