I actually just got Shopsavvy to focus on 2 bar codes too, before this I couldn't get it to focus on anything. On a 3rd attempt it failed though, so I am not sure what it all means yet.
I also snapped 3 photos in a row in a very low light situation and got 3 very quick focus locks with all green corners. One photo of the three was the same subject (my iMac screen) I took a few days ago and tonight I could zoom in and read the text clearly on the screen (I was actually impressed). On the photo from a few days ago it was completely blurry.
This kind of makes sense, think about it. Verizon's flagship device is getting rave reviews but almost all of them punctuated with complaints about the camera. Maybe they felt the heat and prioritized this update, sending it out much sooner than any one would have guessed.
