If you want to use all of the features that an Android Wear smartwatch offers then you are required to hook it up to an Android smartphone. Most smartwatches aren’t 3G or 4G enabled so they need to feed off the data connection from the smartphone. There is no official support for the iPhone yet but Google has never outright denied that support for the iPhone is impossible. Word on the street is that Android Wear iPhone support is coming soon.
It was first rumored last year that Samsung is going to ditch the Qualcomm Snapdragon 810, a processor that is going to power many flagships this year, in favor of its own Exynos 7420 processor. Rumors had everybody believing that this had something to do with the overheating issues that the Snapdragon 810 was facing. It later turned out to be more of a business decision on Samsung’s part, to reduce its reliance on Qualcomm, and the company’s CEO has offered an explanation of sorts on this matter.
