All apps can now be installed, enabled and disabled from the watch itself. Using the advanced settings mode allows you to control the settings on each app from your phone or tablet, using the Smart Connect app. And a calculator has been added, allowing you to perform math right on your wrist.
The update should appear on your watch. If you don't receive it, head over to the Google Play Store to install the SmartWatch 2 SW2 app, found at the sourcelink. You will need to have the Smart Connect app pre-loaded on your phone or tablet.
If you think that the Sony SmartWatch 2 would look great on your wrist, you can pick one up from Amazon, where it is priced at $143.
