I've had the Watch 4 classic since launch and the Body Composition started bad and just gets worse!
I know my body fat from a yearly work health assessment where is has ranged from 17 - 19%. I also have electronic scales where it ranges from 15 - 17%.
However from day one my Watch 4 insisted my Body Fat was around 25% - almost a 10% difference! From 5th February (before the latest update) the measurement now tells me my body fat is anything between 2.5 and 7%!!!!
I understand that this is not a medical device but it's still dangerous to offer a tool that is so inaccurate. Samsung either need to fix this or remove it. It's not fit for purpose and could encourage people to take inappropriate action based on the readings.
Same issue and others have had similar issues mentioned on different threads.
Is there an actual solution to this issue? I'm 13% bf and the watch says I am 20%. Absolutely mad!
Same problem here too! Mine has always been 5-10% off.
