A few days ago, Samsung brought Samsung Internet to its Galaxy Watch 4 series so that users can surf the Internet at the watch when they need it. And this browser is not limited to the Galaxy Watch 4 series, other smartwatches of different brands running Wear OS now support Samsung Internet, and there is no need to upgrade to the latest version of Wear OS.
According to feedback from the Reddit community, non- Samsung smartwatches running Wear OS 2 and later are compatible with Samsung Internet. An example in the community post is OPPO Watch, as shown below. Other users also claimed to have run Samsung Internet on Fossil Gen 5, Casio WSD-F30 and even the third-generation Moto 360. Essentially, any Wear OS (or higher) smartwatch should now support Samsung Internet. The application can be installed through the Google Play store.
