Samsung Health Monitor is an app that enables ECG readings and some other advanced health tracking features for Galaxy Watch users with a Samsung smartphone. However, the company is now tweaking it slightly and it will be limited to users on Android 12 or newer versions of the platform.
App support for older devices will end on December 23, and after that only limited services will be accessible.

The notification will appear on the screen once the app has been updated via the Galaxy Store. It says that the next version of Samsung Health Monitor (1.4.1) is not supported on phones running Android OS 11.0 or lower.
Samsung generally updates its devices regularly, meaning only some fairly old entry-level smartphones and flagships over five years old will be left out.
But if you have a Galaxy Watch with ECG or blood pressure tracking and a device on the wrong side of those limitations, you may need to upgrade eventually.
