Use Your iPhone to Magnify
Sometimes, printed materials can be hard to see. Whether it’s fine newsprint or tiny font on a device user manual, there are tons of times when text just isn’t convenient or pleasant to try and read. Luckily, you don’t have to carry a magnifying glass if you have your iPhone with you.
Just go to Settings > General > Accessibility and tap on Magnifier. Make sure the switch is enabled. Now, you can activate the feature from anywhere within iOS by triple-clicking the Home button or Side button. Your iPhone will then use its built-in camera to act as a magnifier.
