Samsung Galaxy Watch 4 started evaluation: the first wearable OS smart watch with real value for money.

Samsung Galaxy Watch 4 feels deja vu, but it's different. I mean in the best way possible. It looks like the Galaxy Watch, but this iteration is slimmer and more refined. The working principle of the software is similar to Tizen, but the new Google Wear OS platform is practical and accurate.

Samsung abandoned the "Active" brand in its latest product line, but took the sporty Galaxy Watch 4 as the company's flagship product, and continued the "classic" version of Samsung Galaxy Watch 3' s luxury features last year.

There is no rumored blood glucose monitor, but the Galaxy Watch 4 is indeed equipped with a unique three-in-one health sensor for measuring heart rate, collecting electrocardiogram and reading body composition–this is the first major smart watch that provides bioelectrical impedance analysis. Do I feel that Apple Watch 7 is getting nervous?

We still need a few hours of testing to see if Samsung will win the right to boast that it is the best smart watch. This is a hands-on preview of Samsung Galaxy Watch 4.
