Another Problem I found with the latest update is that the touch sometimes registers very late.

The second time I actually tapped the Scanner immediately, but if you notice it took so much time to register my touch. But as soon as the touch is registered, the scanner opens up quickly, so its before the registering of touch thats lagging and not after the touch.
on iOS however I found the touches to be buttery smooth as compared to the previous versions.
