I detected a problem with touch when running an app on different Android units with larger screen than 480x320px.
When running a landscape orientated app with a button/image at the right edge of the screen, touch did not respond at until I reached a bit in to the screen, pretty much same distance as screen is extended on a wider screen 45px on each side (Galaxy Tab on windows simulator).
On the left side it was no problem at all. I also have tried this on real devices with the same result. Desire HD, Galaxy S2 and Galaxy Tab 10.1.
The button is a button = display.newGroup() with an image in it.
I added printouts in eventhandler to make sure I did not miss anything but the event was not called at all when it was not responding.
In short touch outside 480px (x-axis) in landscape mode does not seem to work.
config.lua regarding screen size and scaling looks like this.
1 2 3 | width = 320, height = 480, scale = "letterbox", |
This could be a simulator-specific bug regarding positioning of the skins, etc. I suggest you file a bug report to ensure this gets resolved at some point:

To save on typing you could just give a brief description and a link to this thread. Bugs with test-cases attached (small example project that isolates the problem) tend to get resolved quicker than others (after it's been prioritized).
Also, I suggest you build for device to see if this is an on-device issue as well because that would definitely elevate it's priority.
Thank you very much,
