The Samsung Galaxy Watch 4 offers various health and fitness tracking features, but some are not available for all users. Features like ECG and blood pressure monitoring are restricted to certain regions, and you can't use them if your watch is paired with a non-Samsung device. Thankfully, there is a simple workaround to enable ECG and blood pressure monitoring on the Galaxy Watch 4.

The workaround uses a modded version of the Samsung Health Monitor app from XDA Senior Member Dante63. It bypasses the regional restrictions on the ECG and blood pressure monitoring features and enables the features on your Galaxy Watch 4, even with a non-Samsung device. The process requires a bit of tinkering but is well worth the hassle if you want the BP sync feature.

Making the Galaxy Watch 4 more useful

It's worth mentioning that the blood pressure feature on the Samsung Galaxy Watch 4 should only be used as an indication of trends in blood pressure between regular checks by a healthcare professional. It is not a replacement for traditional methods of monitoring blood pressure. You should not take any clinical action based on the readings offered by the Galaxy Watch 4 without consulting a qualified healthcare professional.
