On this update I did notice my haptic vibrate feedback is not as strong or should I say it does not vibrate like it use to. I increase it all the way up but it still feels lite. I think it was set this way for better battery life. But this should be set by the user not an update.
On mine the vibration intensity for the bottom keys is very faint but not completely gone, so it may seem that it is off. (I actually like it that way).
