Q: Selfie Stick doesnt work anymore since iOS 9.2

Is this selfie stick connected via Bluetooth? Have you checked to make sure the stick is charged? Did you try resetting the stick, removing the stick from the phone, putting the stick back into discovery/pairing mode, and then trying to connect the stick again?

Do regular headphones work?

Try a different Selfie Stick.

Then I suggest you contact the manufacturer and see what their support has to say.

Borrow one.  Test one out in a store that sells them (tell them you want to know that it works before you buy it).  Buy another one.

Try setting your volume on mute. That's how I got the selfie stick to work after I updated the ios.  Good luck.

Bummer muting the sound worked temporarily so still looking for a fix.

I have exactly the same problem. With the new IOS 10 - none of my selfie sticks work. They do with my iPad !
