First Look at the Samsung Galaxy Watch 4 Classic - MAJOR CHANGE! The Samsung Galaxy Watch 4 and 4 Classic are the subject of my first official hands-on review in this video. Upgraded hardware components, a new 5nm chip, and new software with Google's Wear OS and One UI watch merged are just a few of the new features! In my full unpacking and review video, I'll test battery life, workout modes, and the Samsung Bioactive Sensor, a three-in-one health monitoring device. Specifications, pricing, and a launch/release date are all covered!
