iPhone white barrs problem and Android zoom in and out

Hi i have two problems with my game.

iPhone 7.1: I rotated game to landscape, a grey bar appeared at bottom of screen, cutting the game canvas.

Android 4.1.2: On Android, I did not encounter the grey bar at bottom of screen. However, when I clicked to play game, the game canvas zoomed in. At second click, the game canvas zoomed out, making play difficult and confusing.

I didn t encounter the zooming issue, however I saw that the HUD flickered a little (like if it wasn t on a layer with no parralax)

As for iOS devices I don t own one so I might say something wrong, but maybe a fullscreen mode could help with that?

Sorry for not being very helpful

It could be cause of the DOM elements (textbox) Causes this. I have had this trouble before.

And how did you solve it?
