One day my mobile was dead because of empty battery. I recharged the battery and turned on the mobile. Mobile showed a message "Android is upgrading" while turning on. After that Speaker and Mic are not working. There is no any type of sound coming out of mobile and I cant input my voice through mic. Sometimes Phone app acts very slow.


  • MotoG 1st Generation
  • Android 5.0.2 (Lollipop)
  • Build No. LXB22.46-28
  • Dual Sim
  • Internal Memory 16 GB

What I have tried:

  • Restarted my mobile many times (No Result)
  • Restarted my mobile with Safe Mode (No Result)
  • Factory Reset (No Result)
  • Clear Cache Partition (No Result)
  • Once I restarted with QCom option from power options (Speaker and Mic started working . I restarted again with normal mode and still speaker and mic was working but after some minutes speaker and mic were dead again)

Any suggestions?

Surprisingly I was able to fix this issue in my phone by changing following wi-fi settings:

Go to advanced wi-fi setting. You will find a toggle option "Scanning always available". Disable this option.

Worked for me.


I was facing similar problem in my moto g 1st generation with Mic only.

I have also tried some option as you said. See my efforts at

Moto G Microphone is not working

After update also it was not working. But after cleaning MIC hole in my mobile now its working fine.
