Your question is confusingly phrased. Do you want to zoom in then zoom back out, or do you want to not zoom at all?
Excuse my bad english.
Take a look at this example on a smartphone I hope this will show the problem
There are input Fields, when you play the game. The smartphones zooms in as soon as the focus is in the input field. Even though I have put a big font-size for the input field. A big font-size is the normal procedure for stopping that zooming. But this does not work for Animate CC (Jquery) input components.
So thats the problem. So As I cant stop this automatic zooming. I am looking for a command to zoom out after the user has put some text in the input field, or after he has clicked a button.
What you can do is add a viewport meta tag to prevent the browser from scaling the page.
