Input text dosent always work on mobile devices, Android and iPhone

I have a few input text boxes in a game for the Android and iPhone platforms. These control passwords, user names ect…

Sometimes it is really hard to select the text boxes, I have to click on the multiple times. It is very temperamental. People are getting frustrated with this.

Does anyone else have this problem or any solution?

Thanks
Richard

You can try to upscale all the GUI :

	private void OnGUI(){
	float scale = 1.5f ;
	GUI.matrix = Matrix4x4.Scale( new Vector3( scale, scale, scale )  ) ;

	// Your code
	}

But be careful it will upscale all the GUI
