Creeped out? Many people are. Lots of consumers don’t trust their virtual assistants and wonder how to switch them off. If you’re worried about the privacy risks of your smartphone’s always-on microphone, here are tips on how to turn it off:

When you put the Facebook app on your phone, it requests access to your microphone. Why? Facebook needs to record your voice when you shoot live video. But some people are wary of this. Does the app only record you when you’re on camera? Or is Facebook “listening” through your microphone?

Facebook denies these claims, and there is no solid evidence to support this fear. But you are absolutely welcome to sever the tie between app and microphone. Many people have no use for this access anyway, so there’s nothing to lose by switching it off.

If you are an iPhone user, go to Settings >> Facebook >> Settings >> slide the Microphone switch to the left so it turns from green to white. That turns it off. Alternatively, you can go to Settings >> Privacy >> Microphone >> look for Facebook then do the same. Note that you can toggle the mic on and off for other apps, too.

For Android users: Try Settings >> Applications >> Application Manager >> look for Facebook >> Permissions >> Turn off the mic.

If you do decide to shoot video later on, just return to those settings and re-establish a connection to your mic. You can always switch it off again when you’re done.
