Text location (y) differs by device in Simulator

Not sure if this is a known issue, but my text is showing up at slightly different y locations on various devices. I am using a letterbox config, with the resolution at 640x960. 
I believe it has something to do with the letterboxing, because the y offset tends to sway based on whether its wider/taller. 

Additional info- I am using the last stable release, not a daily build. It appears to go both up and down, depending on device (as compared to the iphone4). 

Sorry if I’m hijacking but I’m having same issue but haven’t started to track it down. I still don’t know if its platform specific or device specific problem. 

I make the design pixel perfect on simulator, load it up on iOS device and its little bit off and on Android its several pixels off.

An example is I’m underlining the players name when its his turn and on android the line goes across the bottom half of the font. 

Hoping for some good solution.

What version of Corona SDK are you running?

In general if you start with empty text ("") you may get positioning problems.  Also different devices render fonts differently.  We’ve made improvements in particular if you start with an empty string, but all of those fixes should be in by the latest stable release 1137.
