Mine vibrated yesterday and now it wont vibrate. If you scroll down from the top on your home screen, click the icon in the top right corner, that should bring up your wifi, airplane mode, gps, battery, etc icons. If you scroll down to audio profiles, there is one called meeting that has a picture of a phone vibrating. That should make calls and messages vibrate your phone. You can also manually turn them on because if you go to settings/device/audio profile/settings for general where you can select vibrate plus ring, and if you scroll down there is an option for vibrate on touch. Even though I have both these settings checked, and they used to work, they are no longer working. I tried a factory reset, and that didn't fix it. Now, when I power on my watch, I get a message that says headphones disconnected. It seemed to stop working after I started getting this message, not sure if that is normal or if it has anything to do with it. I will let you know if I figure out a way to get mine vibrating again, but for now it looks like mine could be broken. Can anyone else chime in on this if this has happened to you?
