Samsung says it can transition between cellular and Bluetooth connections seamlessly. It includes Samsung's S Voice service for voice commands, and has an on-screen keyboard for composing messages. Other features include Samsung's S Health and fitness apps, music player and gallery apps, and the ability to receive notifications from a variety of services. The Gear S is powered by a dual-core 1.0GHz processor with 512MB of RAM and 4GB of storage. It has a 300mAh battery, which Samsung claims provides for two days of usage per charge.
