Why isn't the microphone on my LGK7 working?

[Julia Ward]

I was talking on the phone and suddenly the person on the other end of the line couldn't hear me. If I turn on the speaker they can hear me but as soon as I turn the speaker off they no longer can hear me. Also Google won't respond to voice commands. I called tech support and their only answer was a master reset. I wouldn't do that because II'm pretty tech dumb and I don't want to lose all of the info I have saved. Please help!

Welcome to Android Central! First, check the primary phone mic opening to make sure it isn't clogged or blocked. If it's clear, then try booting into Safe Mode, which temporarily disables all 3rd party apps. https://support.t-mobile.com/docs/DOC-24880

If the problem disappears in Safe Mode, then something you installed is causing the problem. You may have to uninstall apps one by one until the problem disappears. If the problem persists in Safe Mode, then it's more likely to be a hardware or firmware problem.
