Fitbit flex 2 vibrates without a reason

[MirjamA]

My fitbit sometimes vibrates out of no where with no reason. This happends especially in the morning. It vibrates then 3 or 4 times after eachother and all the lights start flickering and one of them is red. But i didn't set an alarm, i haven't moved yet and i didn't get any messages or calls. I have no idea why it vibrates and this happends around 1 time per 2 weeks. Anyone knows why? Or is there maybe a malfunction?

That sounds really weird! Try restarting your tracker several times and see if that helps. Let us know how you go

My Flex 2 often vibrates for no reason too. I would really like some help with it too. It’s always on the half hour and outside the hours I’ve set for the reminder to move. I don’t have any alarms set and I’ve checked all my other settings. Can someone please tell me why it vibrates?

Mine does the exact same thing. Nobody seems to know why.
