I got a Gear Fit for Christmas. It works through the S Health app. My S Health app does not work on my phone. All it does is has a pop up "unfortunately stopped", therefore making my Gear Fit useless. I have tried the advice of many other users whose S Health app didn't work at all, much less with Gear Fit to fix. I've uninstalled, then reinstalled, powered off the phone, nothing works. I'm running a marathon and I cant use anything but a 3rd party to chart my history...very frustrated, please help!!
