Samsung developed its Samsung Health app as a one-stop solution for Galaxy device owners. It offers a wide variety of health and fitness-related features. The app comes pre-installed on the company's devices so you always have it around even if you don't use it.
It often happens that apps drop support for older devices. The developers might make this decision based on several different reasons. They might want to nudge users towards newer devices or they simply may not see any reason to keep providing support for older devices. A similar decision has been made for Samsung Health.
Samsung Health drops support for older devices
The company has confirmed through a notice that from March 22, 2021, Samsung Health is no longer going to be available for older devices. New Samsung Health updates will not be released for devices running Android 7.0 Nougat or lower.
This doesn't mean that people who have older Galaxy devices won't be able to use Samsung Health. They can continue to use the app but it will only provide access to limited services and features. Since the app won't be supported for those devices, they won't receive any updates so new features are out of the question.
Samsung recommends that users should upgrade to Android 8.0 Oreo or higher if they want to be eligible for the latest versions of Samsung Health. If you have a device that's not eligible for an upgrade beyond Android 7.0, you're going to have to change devices.
