The App Store has several programs that borrow the iPhone’s camera and use it to display a magnified view of objects in front of the device, but the current iOS 10 system software comes with its own Magnifier function. This tool is part of Apple’s suite of Accessibility features.
To use the Magnifier on an iOS 10 device, open the Settings icon and select General. On the General settings screen, choose Accessibility and then Magnifier. On the next screen, tap the button to the On position. Press the Home button to return to the iPhone’s main screen.
Now, when you want to read the fine print on the page or need to get a close-up look at something, press the iPhone’s Home button three times quickly. This triple-click action (also known as the Accessibility Shortcut) brings up the Magnifier and any other preconfigured functions geared toward users with impaired vision, hearing or motor skills.
When you have the Magnifier open in a dark restaurant, tap the lightning bolt icon on the screen to turn on the iPhone’s flash for a steady stream of bright light. Tap the Filters icon to change the color cast on the screen. You can zoom in by dragging the slider on the screen and tap the padlock icon to lock the camera’s focus.
If you want to freeze the frame, tap the round camera shutter button. Once the frame is frozen, you can zoom to the part you want to see better. Press your finger on the screen and select Save Image if you want to keep a copy in your Camera Roll. Tap the shutter button to unfreeze the frame, and press the Home button to leave the Magnifier.
The iOS Accessibility settings have a Zoom feature for making things larger on the iPhone screen itself. For Android users, Google includes a similar feature, and Microsoft’s software for its Windows Phones has a Magnifier too.
