Apple Watch 4 Phantom Vibrations
Just noticed today, May 9, 2019 - small vibrations coming from the watch. I thought I was getting a message. Watch is updated as is my IPhone.
Also noticed that my watch face had changed around the same time.
Found that if I turn Haptics off, it seems to go away. Of course that isn't a viable cure. But I have done that.
About 10 days ago every time I touched the face it would speak the time etc. I did a reset and that took care that problem. I will do the same maybe tonight.
I purchased the watch for its AFib capabilities, so that doesn't seem to be affected.
