Screen icons doubled in size?

[nbpoppy]

I inadvertantly carried my uncovered 4S loosely in my hand for a couple of minutes with the screen live. When I checked it, the screen icons had doubled in size and the phone had become almost unuseable. I eventually managed (with great difficulty) to turn off the phone and when I restarted it, it was back to normal.
Why did this happen and, is there a simple way to get things back to normal?
Many thanks,

Colin

Do you have Triple-Click set to Zoom in Setup?

Can't find 'setup', but a triple click doesn't do anything?

My little one done this on my 3GS a couple of year ago. It was reset by tapping the screen with 3 fingers at the same time. Try that
