5 little-known features in iPhones

Posted on Updated on

Unless you’re constantly messing around with your iPhone’s settings, most people don’t dig into the Accessibility features in iOS unless they need to solve a specific problem. That said, there’s actually a few great features hidden in those options that everyone can make use of, even if you don’t need them.

The iPhone’s accessibility options are pretty fantastic and cover a lot of ground. They’re also easy for anyone to enable and play around with under Settings > General >Accessibility.

Here are a few cool things you might not realize you’re iPhone can do.

Read text aloud with voiceover or speak selection

If you don’t mind being read to in the robotic voice of Siri, you can set up your iPhone to read any text you want aloud to you. Turning it on is incredibly easy:

Head into Settings > General > Accessibility

Turn on VoiceOver

Turn on Speak Selection

Now, when you select a block of text you’ll get the option to speak it out loud. That’s not all though, as IT World points out, if you select the first line of a block of text and then swipe down with two fingers your iPhone will read everything on that page out loud to you.

Get LED flashes for notifications
For whatever reason, the iPhone doesn’t have a good system for providing a visual alert other than the screen turning on. If you want an alert that draws a bit more attention than just the screen, the LED notifications are pretty handy.

Just head into Settings > General > Accessibility, and tap the LED Flash for Alerts button to enable it. Now, when you get a call or other notification, the LED flash on the backside of your phone will light up.

Enable custom gestures with AssistiveTouch
The AssistiveTouch option in iOS is one that few of us bother messing around with. The point of AssistiveTouch is to help people who have problems with the touchscreen, and subsequently you can do all kinds of cool stuff with it, including creating your own set of gestures:

Turn on AssistiveTouch in Settings > General Accessibility > AssistiveTouch

Tap the new icon in the top left corner of your screen Tap the Favourites button Tap the “+” to create a new gesture. Here you can enable you own gestures. This is useful in all kinds of ways. The blog Here’s The Thing has a few examples, including making scrolling easier:

For example, to scroll up on a lengthy web page without actually swiping, you could just call up the AssistiveTouch menu, tap Favourites, and then the icon for your new “swipe down” gesture.

Now tap the screen, and it’ll obediently scroll down just as if you’d swiped it.

The AssistiveTouch setting is actually incredibly helpful for all kinds of things, including taking screenshots without having to tap the power button and home button at the same time, and using your phone’s home button when it’s broken.

Enable different vibration patterns for different contacts
The custom vibration setting has moved out of the Accessibility options in iOS 6, but since that’s where it started in iOS 5 we’re still happy to include it here. Essentially, it makes it so you can set up custom vibration alerts for your contacts so you know who’s trying to get a hold of you without ever looking at your phone.

In iOS 6, just click on a contact, select Vibration and then choose Create New Vibration. Now tap out whatever vibration you want. If you’re still on iOS 5, you can find the setting under Settings > General > Accessibility > Custom Vibrations.

Enable guided access to lock off apps when you hand your phone to kids (or strangers)
Guided Access was introduced in iOS 6 as a means to make it easy for pretty much anyone to use an iPhone without messing anything up. Guided Access can restrict your iPhone to just one app, disable parts of the screen, or turn off any of the hardware buttons. As Cult Of Mac points out that makes it great for when you need to hand your phone over to a friend or child.

To enable it, head into Settings > General > Accessibility > Guided Access. To enable it when you’re in an app, just triple-click the home button, pick the settings you want, and hand it over to the person who wants to borrow your phone. I’ve found this especially helpful in those awkward situations when someone asks to borrow your phone to make a call.
