There are workarounds, such as MyFitness Pal and Health Sync app, these require interim services however.
Please intigrate Mi Body with Samsung health app. I have the Body+ scales.
The only reason I purchased the Mi Body Composition Scale 2 was because it is listed in the Samsung Health app as an Accepted Accessory. I assumed it would automatically sync with my Samsung Health app. Now I'm very disappointed and wish I'd done more research before buying it. I didn't think I had to since it was listed right there in Samsung's app! They should remove the Mi Smart Scale entry from the app since it doesn't work. Don't fool more people into buying them just to make them see they wasted their money.
