Samsung Galaxy Watch 4 supports a wide range of health and fitness tracking features. However, some of these features are not available to all users. For example, ECG and blood pressure are limited to certain regions, and you cannot use them when the clock is paired with a non-Samsung phone, even in supported regions. Fortunately, there is a solution to get these features in all regions, even on non-Samsung devices. If you’re using a Galaxy Watch 4 with a non-Samsung phone or don’t have access to features due to regional restrictions, here’s how you can activate the ECG and blood pressure on your Galaxy Watch 4.
