Size home page icons suddenly increased

Apple iPhone - Unable to decrease the size of home page icons as suddenly increased

My iPhone icons are suddenly increased to very large size, unable to move normally and unable to make it normal size, even restart after also unable to make it normally. Can anybody can help me how can i get it as normal?

iPhone Tutorial
Use three fingers and double tap on that zoomed screen. It should go to normal size. You have evidently set your zoom to ON in the settings>general>accessibility> zoom options.

You can turn the zoom OFF or remember that anytime you double tap with three fingers you will zoom and doing the same again gets it back to normal.

-----
Three finger tap.
Should return to normal.
It's a *feature*.

It is likely that Accessibility Options are tuned on. With the phone on push on the home button 3 times. Then you can turn on or off voiceover, zoom, and white on black.
