In order to connect your Galaxy Gear Fit with your Samsung device, there are some steps you need to follow. Before that, check if your phone has a high Android version, for example Jellybean 4.2.2. Pair your Samsung with Galaxy Gear Fit and install the manager on the phone you want to run the it. After those 2 steps, you need to open up a file manager app and select Galaxy Fit manager. Save a backup in DropBox or Google Drive, use the phone to pair them and then download it. Install the application and then sync. You might get some failures while using your device, but it’s normal after this kind of process.
