Software
editThe smartwatch was the first watch released by Samsung to use Wear OS instead of Samsung's own Tizen OS.[7]
This smartwatch is region locked in mainland China, unlike past models.
Supported languages and regions
editUnlike past Wear OS devices, Wear OS 3 supports a wider variety of languages that the end user can choose from. An ADB command can be used to temporarily change the watch's language to another one, which will reset when the device is reconnected to the phone.
Depending on the region where the device was sold from, the language and region options may differ.
