I was woken this morning to my fitbit vibrating constantly as it was entering and exiting the timer mode, then found that it would randomaly shuffle through menus as if the button was being pressed and sometimes held. I started to google on my phone what was happening and shortly after I started searching it stopped. so I layed back down and within five minutes it started again. I looked up restarting my fitbit and preformed that. it contunued to act as though it was being pressed. I tried restarting it a couple more times and it seems to have stopped for now. but I was wondering what could have caused this.
