The first Apple Watch update appeared a few days ago. This update brings with it “improved performance” for Siri, different elements of activity tracking, accessibility and third party support. 1.0.1 also brings Brazilian Portugese, Danish, Dutch, Swedish, Russian, Thai and Turkish language support. And a few minor security issues were addressed. In short, you might want to run this one… To do so, first make sure your phone is close (less than 20 feet in my opinion) and that the watch has at least half a charge.
To run the upgrade, start by opening the Apple Watch app on your iPhone. From the default screen (My Watch), tap on General and then tap on Software Update.
From the Software Update screen, tap on Download and Install and let the watch do it’s thing (note, you’ll be prompted for a passcode if you have one configured). The update usually takes around 15 minutes. Don’t reboot or get the phone more than 20 feet from the watch during the update. Enjoy your Brazilian Portuguese!
