Although, users were so excited about the update, Android Wear 2.0 is unfortunately not for the Smartwatch 3.
The Sony Smartwatch 3 was one of the first Android Wear smartwatches on the market, however, the product page for Smartwatch 3 Xperia Blog stated that the device will not get the software update. Thus, the device will remain on Android Wear 1.5.
The device could work with Android Wear 2.0, too. But the decision not to get the update likely has to do with its chipset that lags behind the smooth experience powered by the Snapdragon Wear 2100.
Sporting a square design, the Smartwatch 3 has NFC, IP68 rating, and built-in GPS.
