Fitbit HR is separating below the display and the band.

Hello, Sadly this is a problem with any FitBit Charge, my FitBit did the same thing. But, when I did I emailed Fitbit and my Fitbit was still in warranty so they replaced it! If your Fitbit is not in warranty anymore they will give you a 25$ credit for their online store! Hope I Helped!
