The Apple Watch dominates the wearable device 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 is the only smartwatch on Android that runs the latest version of Wear OS with Samsung’s One UI Watch. While it has many health tracking capabilities, it loses some important features depending on its region. For example, blood pressure monitoring is not available on the Galaxy Watch 4 in the US region at the time of this writing in April 2022.

Fortunately, there is a workaround for this problem. If you have a Galaxy Watch 4 or Galaxy Watch 4 Classic, here’s how you can enable the blood pressure feature (and also ECG 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 that the claims are legitimate. The ECG feature was approved by the FDA in the U.S., 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’s a drawback as both are useful features. However, if you want to try those features on your Galaxy Watch 4, there are ways to test them.

Samsung claims that Blood pressure monitoring will be officially available for the Galaxy Watch 4 in the near future. It has been 6 months since the release of the smartwatch and the update has not yet arrived.

Supported regions and devices

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

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

How to enable blood pressure monitoring on Galaxy Watch 4

In addition to your Galaxy Watch 4, you need a smartphone and a PC or Mac to download the app on the smartwatch. Once you have them all ready, you can proceed with the steps.

Note that this will also enable ECG in your region if it is not officially supported.

ADB setup and watch connection

We will use ADB (Android Debug Bridge) to install an app on Galaxy Watch 4. If you haven’t done it before, you can refer to our guide on how to install APK on Wear OS smartwatches.

Step 1: Download the relevant ADB files according to the operating system you use on your computer.

Step 2: Extract the ZIP file to the location of your choice. On Windows, hold down the Shift key and right-click on the extracted file and select “Open command window here”. On Mac and Linux, open Terminal, type cd and press Enter to change the active directory. Then drag the folder you unzipped and drop it into the Terminal window. You will now get a path to that folder in the Terminal. Press Enter.
