While traveling yesterday - actually staying in a crummy Days Inn in Washington, PA - my Verizon S3 updated to Kitkat. Since I've been traveling, and 2 days spent roaming in Canada, I haven't had much time to play with it and see the differences. Regardless of changes, it's pretty cool that a now 2 year old phone is still getting official updates.
One change is that the flashlight app, once called "Assistive Lighting" is now called "Flashlight."
Also, does anyone know what the icon is next to the Sound Muted icon is?
