My phone did an automatic update this weekend. I'm now at 4.3 build number JSS15J.1337UCUEMK2. I can provide more info if needed.

After the update my phone vibrates constantly during a download. Doesn't matter if it is music, an new app or an update to an app. This is really annoying!

It also vibrates constantly when I try to make a call and for several seconds after the person I am calling has answered. It does this on both outgoing and incoming calls. This issue is even more annoying!

I can make both of these things stop if I turn vibrate off but then I don't get any vibrate alerts that I want.

Anyone else out there having this issue or know how to fix it?
