There are lot of new features in iOS 8 and several smaller features that are very useful, but might slip by unnoticed. This article list out the best hidden features in iOS 8.
Systemwide Hindi support
Finally, you can set Hindi as the system language in iOS. Go to Settings > General > Language & Region > iPhone Language > Hindi. This doesn’t just change the keyboard, but the entire UI as well.
New Indian language keyboards
Full system support for more Indian languages will take longer to arrive, but we have more keyboard options than before. Hindi and Tamil keyboards were already available in iOS 7, and the latest update adds Marathi, Bengali, Urdu and English (India) keyboards. Settings > General > Keyboard > Keyboards > Add New Keyboard.
Hide keyboard prediction by swiping down
Speaking of keyboards, if you don’t like the word predictions that pop up above the keyboard, you can quickly hide them. Just place your finger on the predictions and swipe down. To reveal these again, swipe up in the same place.
You don’t need to press and hold the home button to use Siri anymore. If your device is charging, just say, “Hey Siri” to activate it. Enable this at Settings > General > Siri > Allow “Hey Siri” > On.
Siri buys songs, identifies them too
You can also ask Siri to purchase content on the iTunes Store now. Also, it can listen to music and identify the track for you. Ask Siri what song is playing and it will listen and answer, via Shazam.
Zoom out to tab view in Safari [iPad only]
When you’re Safari on your iPad, you can zoom out all the way to tab view. Use the pinch gesture (two fingers) to do so. This can be handy if you’ve got a lot of tabs open and want a quick preview to find the page you want, or even if you want to rearrange them.
Safari tab search button [iPad only]
When you reach tab view, you’ll see a Search button on the top-left. This lets you find a particular tab, which is useful if you’ve opened too many tabs and can’t find what you need in the previews. It searches tab titles, so just enter the name of the website or title to find the right one.
Reader View Available text in Safari
Safari has a nice Reader View feature, which removes clutter from websites to make them reader-friendly. If Reader View is available on any website, Safari now shows the text: “Reader View Available” in the address bar. Just tap the three horizontal lines on the left side of the address bar to activate it. Once activated, you can increase or decrease font size as well, which wasn’t possible in iOS 7. Tap the big A button at the top of the page to increase text size and the small button to reduce it.
Request Desktop Site, close iCloud tabs
Stuck on a terrible mobile website? Tap the address bar, swipe down the list of bookmarks and you’ll see a Request Desktop Site button. Tap it to open the desktop view. You can finally close iCloud tabs from other devices. iCloud tabs let you sync open tabs across your Apple devices. Previously it wasn’t possible to close iCloud tabs from other devices. Now tap the tabs button in Safari, swipe upwards to iCloud Tabs and swipe left on any of the tabs to reveal a Delete button.
You can now set privacy-focussed search engine DuckDuckGo as default in Safari. Tap Settings > Safari > Search Engines > DuckDuckGo.
Scan credit card
Open a shopping website or any webpage with a form for filling credit card details. Safari will show you an option called Scan Credit Card above the keyboard. Tap it to take a picture of the credit card and have Safari key in the details for you.
Recent, favourite contacts in app switcher
Double tap the home button to open the app switcher. At the top you’ll see a list of people you’ve contacted recently. Swipe to the right to see your favourite contacts. This can be changed by going to Settings > Mail, Contacts, Calendars > under CONTACTS, tap Show In App Switcher. You can select whether you want to see recent contacts, favourites, both or none.
iOS 8 has advanced zoom controls. While this feature has been designed for the visually impaired, it’s quite useful when you want to zoom in apps that don’t support it (such as Instagram). Head to Settings > General > Accessibility > Zoom. Now turn on Zoom and Show Controller. After this, double tap with three fingers anywhere in iOS and you’ll see a pop up that lets you zoom in and out. Drag three fingers on the screen to move round the screen.
Want a nice black-and-white interface? Enable Greyscale mode by going to Settings > General > Accessibility > Greyscale > On. It’s not useful for most people, and is meant for the colourblind, but it could be useful for when the screen looks confusing.
This feature lets you block parts of the app and control how long you want to let others use an app. This is very useful for parental control. Go to Settings > General > Accessibility > Guided Access > On. In the same place, also switch on Accessibility Shortcut. Now open any app that you want to let others have limited access to. Triple-click the home button and tap Options. You can choose how long you want to let the person use the app and whether they can use the keyboard, volume, sleep/wake buttons, and even whether they can use the touchscreen.
Create a blank home screen
iOS 8 lets you go minimalist on the home screen. Just move all icons to the next home screen and you can finally create a blank home screen. This is really not useful, unless you want to make sure people can check out your cool wallpaper.
Send last known location
When your iOS device’s battery is critically low, it sends its last-known location to Apple so that you can track it via iCloud. This is useful in case you lose a dead phone. Settings > iCloud > Find My iPhone/Find My iPad > Send Last Location > On.
Open the Photos app. Make sure you’re in the zoomed out view (where you can see multiple photos). Tap and hold any photo and press Hide. In the pop up, tap the red Hide button. This will hide your photos from the Moments, Collections and Years views, but will keep them visible in the Albums view.
The Mail app in iOS 8 has some nice new gestures. Open your inbox and try a short right swipe on any mail to reveal a Mark as Unread option. Swipe to the left to reveal three options – More, Flag and Archive. You can change swipe actions by going to Settings > Mail > Swipe Options.
Add to contacts, create calendar events
The Mail app also prompts you to create Calendar events and add people to Contacts if it spots the relevant details in the mail.
Notifications for email replies
You can also set up notifications for replies to any mail thread. Open your inbox, slowly swipe to the left, tap More > Notify Me… > Notify Me. You can also set up notifications while composing any email. Tap the bell icon in the subject field > Notify Me.
Drafts to inbox swipe
Start composing a new email. Now swipe downwards from the top where you see the text “New Message” or the email subject. This puts emails in a tab view-like area below the inbox. It makes switching between the inbox and multiple drafts really easy.
GIF images in Notes, rich text editing too
You can finally add GIF images to Notes and use rich text formatting too. Select text, tap the tiny right arrow and tap ‘BIU’.
iOS 8 lets app developers make notifications interactive. System apps such as Calendar support it already. Pull down the Notification Centre and swipe left on any notification to see more options. This lets you hide individual notifications as well as perform actions such as accept or decline Calendar invites.
Text character count
Sending an SMS and want to make sure you aren’t exceeding the 160 character limit? Go to Settings > Messages > Character Count > On. Whenever you type an SMS, you’ll see the character count above the Send button.
