According to your description, there is no pre-installed version of S Health of Samsung S5 series mobile phone you consulted. I suggest you:
1. Back up the data of the mobile phone and restore the factory settings to see if it can be restored (Settings-General-Reset-Restore the factory settings).
2. Go to Samsung Service Center for installation. Please visit the address of a specific service center:
