Samsung leaks the Galaxy Watch ahead of schedule | Android and Me. As the owner, and lover, of all Samsung Galaxy products; especially, the Smartwatches, I am excited about the next version. It won't be the S4, which is the sequential successor to my current Galaxy S3. It will be called the Galaxy Watch, and it will run the same OS as its predecessors, Tizen OS. I am happy about that; because Tizen is superior to Android Wear. If the new watch makes improvements on the S3, I will buy it. But, I remain to be convinced. Since I love the fact that the watch can also serve as its own phone and data source, with an LTE chip, I will get that version, if available. My prediction is that the watch will be smoother, faster, and lighter and slimmer. But, what do I know?
