Somehow I got into zoom mode on the iphone - I think something like two presses of the Home Button - though not precisely since two presses would show the running apps. I got into zoom while fat fingering the "show running apps".
It was difficult to get out of zoom as well.
So then it would be useful to completely disable whatever button shortcuts get us into that mode.
The following link has instructions on how to disable zoom http://www.technipages.com/iphone-enable-disable-zoom.
However I already do have that turned
off: so that is not sufficient. Any other way to completely disable the zoom?
