The screen on my iPhone 4 pops out to enlarge everything. How do I get it to return to normal without going through the shutdown process?
Many apps let you zoom in or out on specific items. For example, you can double-tap or pinch to expand webpage columns in Safari. But, there’s also a Zoom accessibility feature that lets you magnify the entire screen of any app you’re using. And, you can use Zoom together with VoiceOver.
Turn Zoom on or off: Go to Settings > General > Accessibility > Zoom. Or, use Triple-click Home. See Triple-click Home on page 124.
Zoom in or out: Double-tap the screen with three fingers.
Vary the magnification: With three fingers, tap and drag up or down. The tap-and-drag gesture is similar to a double-tap, except you don’t lift your fingers on the second tap—instead, drag your fingers on the screen. Once you start dragging, you can drag with a single finger. iPhone returns to the adjusted magnification when you zoom out and in again using the three-finger double-tap.
Pan around the screen: While zoomed in, drag the screen with three fingers. Once you start dragging, you can drag with a single finger so that you can see more of the screen. Or, hold a single finger near the edge of the display to pan to that side. Move your finger closer to the edge to pan more quickly. When you open a new screen, Zoom goes to the top-middle of the screen.
