Samsung is restricting access to the cardiogram and blood pressure reading of its watches to its branded cellphones, although there is a way to overcome this obstacle: we show you how you can use the advanced health features on your Samsung Galaxy Watch 4, even but not associated with a Samsung mobile.

The latest Samsung watches incorporate a large number of sensors and are compatible with most Android devices, but with nuances: some health functions are exclusive to Galaxy phones. If you bought a Watch 4 or a Samsung Galaxy Watch 4, and you don’t have a branded phone, the EKGs and blood pressure are out of your health record. Fortunately, you can get the APKs.

A modified Samsung Health Monitor app works the magic

Samsung is building a healthy bridge between its watches and phones with the Samsung Health sports app. This can be found on Google Play and is valid for most Android devices, but for EKGs and blood pressure a different and exclusive app for the brand’s cellphones is used: Samsung Health Monitor. This is where the problem lies.

Samsung does not offer all the features of the Galaxy Watch 4 to non-branded cellphones, which is a distinct disadvantage for those who buy the watch believing their options are universal. Still, there is a way around the trap as a Samsung health monitor modified by user Dante63 from XDA Developers can be used.

The modified application is installed on the Samsung Galaxy Watch 4 (there are versions for previous watches) and on the phone where the watch is registered. This link allows you to use advanced health features even if you do not have a Samsung mobile. While yes, you should keep in mind that using modified apps poses a risk to your privacy; with the aggravating circumstance that the data to which you will have access are those of your health.

Using modified official apps poses a serious risk to privacy, you should take this into account

Once you assume the obvious risks of using modified official apps, it’s time to start the tutorial. Let’s see how to add EKG and blood pressure to Samsung Galaxy Watch 4:

You must have ADB active on your computer. If you haven’t installed it, start with this step. Once you have ADB, you need to download the two necessary apps: Samsung Health Monitor for mobile and also for the clock, both of which are modified. Go to this Dante63 Drive and download the APK which is in the root of the phonebook (that of the phone) and the APK which is in “ADB Watch4” (the app of the watch. Install the APK of the phone on the mobile you have paired with the Samsung Galaxy Watch 4. This is the simplest step. Make sure that the watch and the computer are connected to the same Wi-Fi network. Now it is time to install the Samsung Health Monitor application modified on the watch To do this you need wireless ADB: go to the settings of the watch 4, enter “Connections”, go to “Wi-Fi”, enter the network where you are connected and write down the IP address of your watch. Go back to Galaxy Watch 4 settings, scroll to “About clock”, enter “Software” and press “Software version” repeatedly until have the developer options enabled. Enable ADB debugging and “Debug with WiFi.” Open a terminal window su on your computer, go to the folder where you installed ADB (“Platform-Tools”) and write “a db kill-server” (without the quotes) to stop the process. To restart it and make sure that no other device is using the connection, type “adb start-server”. The daemon should start normally. Note that if you are using a macOS or Linux computer, you must write “./” in front of each ADB instruction. The above would look like this: “./adb start-server” (without the quotes). Turn to connect by wireless ADB to your Samsung Galaxy Watch 4: write “adb connect” by changing the Xs to the IP address you entered. Accept debugging on the clock: the terminal should reflect a successful connection. Now is the time to install the modified application on the clock. To do this, save the APK you downloaded in the same folder where ADB (“Platform-Tools”) is running and rename the file to make it easier for you to write the instruction. For example, “shm.apk”. Write “adb -s install shm.apk” changing the Xs for the IP address. You will have installed the modified Samsung Health Monitor app on the watch. The “Success” notice alerts you that the application was installed using wireless ADB. If a “Success” appears on the terminal, the process was successful. Otherwise, you will have to repeat it. Type “adb disconnect” to disconnect the clock from the computer. Now go to the developer settings of the Samsung Galaxy Watch 4 and disconnect the ADB through WiFi and ADB debugging. This step is important: if you don’t, your Samsung Galaxy Watch 4 will drain the battery because it is constantly waiting for a connection.

Once you have the Samsung Health Monitor app changed on the watch and on the phone, you can now use the EKG and blood pressure as if you have a Samsung phone: open it from the watch (you can use it add to cards) and select what you want. Of course, you will need a blood pressure monitor to contrast blood pressure readings – this feature must be calibrated initially. And from time to time.

Setting up and using Samsung Health Monitor on a non-Samsung mobile

You probably have two Samsung Health Monitor apps on the Watch 4: the official and the modified one; the second has an “M” in the icon, you can tell it apart as well. There is the option to remove the serial application using ADB, although this is not recommended: in this XDA Developers thread you have the instructions.

Since you’ve installed a modified Samsung Health Monitor, two apps will likely appear on your watch. The one you can use for EKGs and blood pressure is the app that has an “M”

Once the simple but somewhat cumbersome process is completed, you will have access to advanced health records as if you had a Samsung mobile. Of course, there is a downside to this: the modified app cannot sync blood pressure and EKG data with Samsung Health. This data will always remain in the modified Samsung Health Monitor app.
