I am having trouble with the mobile keyboard resizing the screen when in landscape.
As soon as the focus is changed to the textbox or you click on the textbox and bring up the keyboard, it shrinks the game screen so small you can't even see what you are typing. I have tried messing with the scale rate and parallax with no luck.
If you rotate the phone to portrait, it isn't too bad but that is because there is more room for the keyboard. I have attached a capx with all of the same settings except for my tests and without the auto focus on the textbox.
Let me know if I am missing something or if I have a bad setting and I will report back after giving it a try!
