Does Samsung Watch 4 ECG work with all Android phones?

Samsung Watch 4 comes with ECG and Blood Pressure Monitoring. This is the first time that these features are arriving on the Samsung Watch 4. Previous models of Samsung watch did not have these features. These features have been made possible because of the Wear OS. Samsung Watch 4 is based on the wearable operating system, developed by Google.

ECG and BPM or the blood pressure monitoring features are a very valuable addition to the Samsung Watch 4 series. However, these two features have been locked by Samsung for use on non-Samsung android phones. This means that the ECG and BPM functions will exist on the Samsung Watch 4, but you will not be able to make use of the features on non-Samsung phones.

This restriction has been corroborated by Samsung Watch 4’s users as well. Users who have OnePlus phones have vouched for smooth integration between the Samsung Watch 4 and the OnePlus mobile phones in Europe. However, the ECG and BPM features do not work on the OnePlus phone. This also means that the Samsung Watch 4’s ECG and BPM features are incompatible with mobile phones manufactured by Xiaomi, Vivo, Oppo, Honor, Huawei, OnePlus, POCO or Nokia.

Samsung Watch 4 ECG functionality will work with the Samsung Health monitoring app. The health monitoring app will not work on non-Samsung phones. Pairing between the Health monitoring app and Samsung Watch 4 is needed to sync the data between the watch and the mobile phone. This limitation on the use of health monitoring app causes the ECG and BPM features to become dysfunctional on non-Samsung phones for now.

The feature lock on Samsung Watch 4 is something that may change in the future as Wear OS gets embraced by more smart watch manufacturers. Quite possibly, we may see the Wear OS being made available to other smart watch manufacturers by Google. Google controls the Wear OS and it is the wearable OS developed by Google. Until that time, Samsung Watch 4 will reap the rewards of being the first one to the feature party involving ECG and BPM feature on the smart watches for Android phone systems.

Samsung Watch 4 will not work with an iPhone. So, if you have an iPhone, you will not be able to activate the Watch 4 device. Therefore, if you have an iPhone please do not consider buying a Samsung Watch 4 for its ECG or BPM features.

We would like to mention over here that the ECG taken from a smart watch should not be used for medical reasons. These readings may be taken as a reference point to collect data of a person’s overall health. Also, ECG app is available for people over 22 years of age. Further, ECG app is not allowed due to regulatory concerns in many countries.

As of today, Samsung Watch 4’s ECG functionality works in US, Australia, South Korea, Indonesia, Chile, UAE and the European Union. The list of countries that support Samsung ECG feature on the Samsung Watch 4 include Austria, Belgium, Bulgaria, Croatia, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, the Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, and the UK.

Conclusion

Samsung Watch 4’s ECG and BPM features will work with a paired Samsung mobile phone. These features have been locked by Samsung for use on non-Samsung phones. There may be some modified versions of the Samsung Health Monitoring app that may allow you to use the ECG function on non-Samsung phones. However, we do not vouch for quality and reliability of such modified versions of the Samsung health monitoring app. And, we are unsure how this will impact the warranty on your Samsung Watch 4. Please do check the fine print before trying to use a modified version of Samsung health monitoring app alongside a Samsung watch 4.
