Thanks @Rob for answering.
I did a little test where I position a rectangle on the screen using the iPhone 6 simulator and the content in config.lua is set to:
width = 320,
height = 480,
Here the X position = display.contentWidth
prints ( 480 )
Here the X position = display.actualContentWidth
prints ( 569.17333984375 )
As you can see, neither of this values is giving me the desired result I need to position the object at the far right of the screen where only half of its body is showing.
Ironically, the Y value for both “contentHeight” and “actualContentHeight” is giving me the desired result. And they both print the exact same position ( 320 )
The orientation is set to “landscapeRight” and when I change it to “portrait” the problem becomes the height instead of the width.
