How to Zoom into Any iPhone Screen
The iPhone has one of the smallest screens of any computer on the market. Every now and then, you might need a little help reading small text or inspecting those tiny graphics.
If you turn on Zoom (in Settings → General → Accessibility), then you can magnify the screen whenever it’s convenient, up to 500 percent. Of course, the screen image is now too big to fit the physical glass of the iPhone, so you’ll need a way to scroll around on your virtual jumbo screen. Here’s the scheme:
• Turn zooming on or off by tapping the screen with three fingers. The screen is now 200 percent of original size.
• Pan around the virtual giant screen by dragging with three fingers. You can lift two of your three fingers after the dragging has begun. That way, it’s easier to see what you’re doing.
• Zoom in more or less by double-tap/dragging with three fingers. It’s like double-tapping, except that you leave your fingers down on the second tap—and drag them upward to zoom in more (up to 500 percent), or down to zoom out again.
