These screencaps are not fake, however, these are not the out of the box features released by Samsung. These are screencaps of an app called My BP Lab 2.0. To make this work on your watch you would actually need a Samsung S9 or Note9 phone or higher, along with the My BP Lab 2.0 app on your watch. In case of this app, the watch does nothing, rather it is the app on your phone that does the tracking using the flash as a sensor to track blood pressure along with using data from heart rate sensor on the watch. I would suggest you guys wait until 3rd week of April 2020 as it is confirmed by Samsung to release ECG and Fall Detection by then.
I just returned my watch back to Costco. Just barely made the 90 day return policy. The watch was fairly nice, but did not have all the features that were advised...most noticable the ecg and the accident fall features. The fact that Samsung hasn't even commented on these features in a very long time indicates they are hoping people will forget about them and that they will most likely not update the active 2 with these features. The ecg feature was one of the biggest reason I purchased the watch to begin with. Oh well, I'll stick with my Sony Zen watch 3 and get the active 3 when it is released and confirmed that the ecg feature is included, at launch. At this point I'd be willing to bet the active 2 will not be getting the ecg feature at all. It's getting pretty comical how far behind Samsung is in regards to their watches compares to Apple's watches. Samsung is 2-3 generations behind. The lesson from all of this is to purchase a product that ships with the features you are looking for. Don't rely on promises that features will be added at a later time. Countless companies have outright lied and false advertised with this false promise.
Are you going to refund all of us who bought this watch because of ECG. You advertised it as being a feature yet you have not given the feature. This is fraud.
