The Samsung S Health you consulted has no pre-installed version, and not all mobile phones support it. If your mobile phone is built-in, but needs to be restored after being deleted by yourself, I suggest you:
1. Back up the mobile phone data and restore the factory settings to see if it can be restored.
2. Go to Samsung Service Center for installation. Please visit the address of a specific service center:
