The Samsung Galaxy Watch 4 (marketed as Samsung Galaxy Watch4) is a smartwatch produced by Samsung Electronics. It marks Samsung's return to Google's Wear OS platform since the earlier Samsung Gear Live, and is the inaugural device to operate on Wear OS version 3, developed in collaboration between Samsung and Google.[1] The design of the watch closely resembles that of its predecessors—the Samsung Galaxy Watch Active and the Galaxy Watch 3—while introducing an entirely revamped software experience.[2] Equipped with the Samsung BioActive sensor, the watch supports features such as electrocardiogram (EKG), body composition measurement, and blood pressure tracking.[3] This model was officially introduced on August 11, 2021, during Samsung's Galaxy Unpacked event alongside devices including the Samsung Galaxy Z Flip 3, Samsung Galaxy Z Fold 3, and the Galaxy Buds 2.[4] The global release date for the watch was August 27, 2021.

Software

This smartwatch marks Samsung's initial device to operate on Wear OS, replacing its proprietary Tizen OS.[7]

Unlike earlier versions, this model is subject to region locked restrictions specifically within mainland China.

Supported languages and regions

Wear OS 3 expands the range of languages available for users compared to earlier Wear OS models. Users can temporarily switch the watch’s language using an ADB command; however, this change will revert once the watch reconnects with the paired smartphone.

The selection of languages and regional settings may vary based on the device’s point of purchase, as indicated by its CSC code.
