Sleep tracker engaging on its own in the middle of the day.

[Chair00076]

Hey, so I've had my FitBit for a week today and I'm totally obsessed with meeting as many goals as I can on a daily basis. A problem I started experiencing yesterday is that my Flex will start to vibrate and when I look down, it's showing the flashing and fading lights that indicate that the sleeptracker is engaged. I then have to tap it to turn the sleeptracker off. It happened once yesterday evening while I was at work (walking around and being quite active actually). Today it happened three more times within an hour. I was out Christmas shopping with friends when it happened the first time and then I was making an hour-long drive home when it happened two more times. It's happened both when I was actively walking around and when I was sitting relatively still. Nothing was near my arm to tap it accidentally any of the times that the tracker was engaged. Is there some sort of trouble shooting I can do? Or perhaps adjusting the sensitivity on my Flex? Or is this something else entirely? Please help. I love my tracker and just want make sure its accurately taking data.

I have only had my Flex a couple of weeks, but I've noticed the same thing. Mine seems to do it while I'm pushing a shopping cart over a rough floor or tapping a spice jar (kinda like hitting a ketchup bottle). Mine's on "normal" sleep mode. I did notice that when I log in, those accidental sleep modes aren't recorded at all, so no problem there. Good luck!

that happens to me when it presses against something.  i wear it at my waist so it happens a few times a week.  like another poster said, for some reason this does not often track on the site.  my regular sleep will but not when its done in error.  odd.

is it possible that it is being pressed on something that could make it start.  i know that sometimes just bending over will do it as it is sandwiched between my hip and my stomach.

good luck.

I've had mine for a couple of weeks..what has happened to you has happened to me a few times..usually when some sort of vibration is going on..I am a teacher and whenever I use the manual pencil sharpener it definitely happens..It has happened on other occasions but very rarely and I usually can catch it really quickly.
