My phone was up-to-date. During today's update which is presumably the Tango update, I have so far seen three seperate downloads and installs and reboots.
Thought it was interesting. I'll reply to this when things finish happily.
Finished without event. Shows 1 more bar of LTE in the familiar spot on my desk. Might not mean anything. ATT has not officially released LTE here so they could be tweaking it.
I took a couple of quick pictures and the camera does take a wider range of photos well at the default settings. I had to switch to Macro focus to focus on the lettering on my mechanical pencil. I would expect to do this for all cameras.
It did change my wallpaper image, which was custom. It's a wall with a wood post. It's a good photo, just not one I like too much.
Oh, and the capacitive buttons light up more often, which is something I wanted.
What should I be looking for?
