At the recent Galaxy Unpacked event, Samsung unveiled several new products, including foldable smartphones Galaxy Z Fold 3 and Galaxy Z Flip 3, Galaxy Buds 2 headphones, and next-generation smartwatches Galaxy Watch4 and Galaxy Watch4 Classic.

The latter are the first wearable Samsung gadgets with a Wear OS-based One UI Watch, an intuitive user interface. Among other features, the company's new wearable devices can calculate body composition.


The new watch is based on the Exynos W920 chip based on 5nm technology. The watch has 1.5 GB of RAM and a storage capacity of 16 GB.

Samsung Galaxy Watch4 received a new BioActive Sensor for measuring blood pressure, heart rate, blood oxygen level, and tracking body composition. This tool provides an in-depth understanding of one's health and fitness.

To start the analysis on your smartwatch, you need to put two fingers on the buttons on the side of the watch. In 15 seconds, the sensor will be able to analyze 2,400 data units based on user-entered height and weight parameters to determine body fat and water percentage, basal metabolic rate, and skeletal muscle. According to Samsung, the technology works with 98% accuracy and is comparable to professional check-ups in medical clinics.

The new smartwatch also features a geomagnetic sensor, as well as an accelerometer, gyro sensor, barometer and light sensor.
