How to Enable Blood Pressure Monitoring on Samsung Galaxy Watch 4

The Apple Watch dominates the wearable industry in terms of popularity and features. However, the biggest drawback is that the Apple Watch only works with an iPhone. The Samsung Galaxy Watch 4 is a solid option for Android users.

It’s the only smartwatch in Android land to run the latest version of Wear OS with Samsung’s One UI Watch. While it has many health tracking abilities, it misses some important features based on your region. For example, Blood Pressure monitoring isn’t available on the Galaxy Watch 4 in the US region at the time of writing in April 2022.

Thankfully, there is a workaround for this issue. If you have a Galaxy Watch 4 or Galaxy Watch 4 Classic, here’s how you can enable the Blood Pressure feature (and ECG too if it’s not available in your region).

Why Is Blood Pressure Monitoring Not Available in Some Regions

All companies products need government approval to include specific health-related features in their devices. That is to ensure that the data derived from the feature is accurate and the claims are legitimate. The ECG feature was approved by the FDA in the US, but approval is still pending for Blood Pressure monitoring.

Both ECG and Blood Pressure are not available on the Galaxy Watch 4 in several regions. That is inconvenient as both are useful features. However, if you want to try out those features on your Galaxy Watch 4, there are ways to try it out.

Samsung claims that Blood Pressure monitoring be available for Galaxy Watch 4 officially in the near future. It’s been 6 months since the smartwatch’s launch and the update is yet to arrive.

Supported Regions and Devices

Even if BP and ECG are officially supported in your region, there is another caveat to using them. You need to have a Samsung smartphone to use with the Galaxy Watch 4. Otherwise, ECG and BP will not work. This guide will also let you use these features on non-Samsung phones. Of course, we don’t guarantee that those features will work flawlessly on all phone models.

As far as the regions are concerned, you can use this guide to get ECG and Blood Pressure monitoring on your Galaxy Watch 4.
