    I've been having this issue for as long as I can remember. Intermittently my phone doesn't recognise any sound. Voice commands don't work, all videos recorded are mute, trying to use a music recognition app and it doesn't pick up any sound.

    After some head scratching I figured out that it only happens after I've connected to something via Bluetooth. The phone will connect to Bluetooth, connection will be broken, and then the problem happens. The only fix is by restarting my phone. Its such a pain that I simply have Bluetooth off permanently, which is a shame cos it can be very useful

    Anyone else had this issue and found a fix?

    That certainly is a shame. More detail would help though.

    What device do you have?

    What kind of Bluetooth devices do you connect to?

    Right off I have two things you can try. Because it sounds like an app is causing your issue, if you can simply restart the phone and it works again something is taking control of your mic and not giving it back once you've disconnected. Should be fairly easy to troubleshoot.

    Go into your device settings>applications and then permissions. Find the permission for your microphone and disable all of the apps that have permission to use it. It's OK when you use the app again it will simply ask if you want to give that app permission to use the microphone, it'll be like a reset.

    Now try to use your Bluetooth, but try this in this order so if there is still an issue it will narrow down what exactly may be the cause.

    >First just turn on the Bluetooth and connect to your favorite device but don't open any apps or play any sound. Then turn off Bluetooth and see if you've lost your mic.

    If you still have your mic

    >Turn on the Bluetooth, connect to a device and open the app you normally use with Bluetooth to play sound and play something. Then turn it off and see if you've lost your mic.

    If you still have your mic then go back to using the phone normally and pay attention to any app that asks for mic permission and notice if you begin loosing your mic again. If you do the last app to ask permission to use your mic is most likely the problem app. Then you can decide if you want to keep it or whatever.

    If you lost your mic in either case above start the phone is "Safe Mode", I would tell you how but we don't know what device you have so you'll have to Google it, and try to use your Bluetooth using the outlined methods above and see if you loose the mic again in either case. For this one you'd have to report back so we can go from here, so become a member to respond to this thread and let us know if either worked or if you need more help.
