One of the eye-catching features that have been added to the newly released Android Nougat is the multi-locale feature. It makes it simple to switch between multiple languages and input methods. This is useful if you have to write in multiple scripts. You can switch the keyboards by pressing the keys on the on-screen keyboard itself and without venturing into the settings every time. You can just set the definite set of languages and keyboards, and switching is just pressing a button. As an example, it means you can switch between English, Japanese, and Mandarin from the keyboard app itself.
Here are the detailed steps to use the multi-locale feature in Android Nougat:
  • Go to Android Settings.
  • Tap on Languages & input under the heading Personal.
  • Tap on Languages.
  • Use the Add a language feature and select an extra language of your choice.
    Adding a New Language
  • When the on-screen keyboard pops up, tap on the globe key or long press the spacebar key to switch between multiple languages that you selected.
Switching Between Keyboards
It is as simple as that. You can now be able to switch the input method between several languages that you selected right from the on-screen keyboard. No more navigating to the settings or installing extra keyboard apps and circulating between them every time you have to change a language. It saves a lot of time for us, multilingual people.

To remove an input method: Go to the same Add a language setting and then tap on the three dots option key and then on the Remove option. It allows you to check and delete multiple languages and input methods at the same time.
Accessibility options in Android allows us to make different changes to the sizes, colors and formatting of the text and items displayed on the screen. For example you can invert the display colors and get a dark theme instead. Previously, the accessibility options allowed us to change the size of text only but in the fresh new Android Nougat, you can also change the dimensions of other on-screen items like images, graphics, message boxes etc. So not only can you increase and decrease the text size but you can also make the items on your screen smaller or larger.

Here are the steps to get to the accessibility options and change some sizes:
  • Go to Android Settings.
  • Tap on Accessibility present in the bottom under System.
Note: The same options are also available in Settings home > Device > Display with the same labels.
You will find many options but take a look at these two:
  1. Font size: Make the text on screen smaller or larger. Switch between Small, Default, Large and Largest. You will also get a live preview.
  2. Display size: Make the items on your screen smaller or larger. Switch between Small, Default, Large, Larger, Largest. The live preview shows how your messaging app looks like.
Font size and Display size
Another important accessibility setting related to on-screen displays is available on the same screen as Magnification gesture. When you turn it on by tapping and moving the slider to the right, you can use shortcuts to zoom what you see on the screen. You can zoom in on any area of the screen. Just tap on the screen 3 times.

Magnification Gesture
As mentioned on the screen, you can also temporarily zoom. Just tap three times while holding your finger on the screen on the third tap. After it zooms, you can drag your finger around to move and navigate through the area of the screen that is zoomed. If you stop touching the screen with your finger, the size changes back to normal as it zooms out automatically.
One of the cosmetic features introduced in Android Nougat is the ability to use different wallpaper for the home screen and the lock screen. Previously, the same image was used when the phone was locked and when you unlocked the phone. Now, you can assign different graphics as the background before the phone is locked and after you punch in that code to access your Android home.

This isn’t a major groundbreaking feature that has been added but it still is nice to be able to set different wallpapers on different screens. Just an eye-candy for many but for those who’d prefer some distinction, you now have the choice. It seems to be a feature added in the Google Now Launcher.
If you upgraded your Android Marshmallow to Nougat, then you will see the same graphic used in the backdrop. You will have to set a new one for the lock screen.

To set it:
  • Open a picture or graphic using your image browser, gallery or photo app.
  • In Google Photos: Press the options button or the three horizontal dots.
  • Tap on Use as and then on Wallpaper.
  • After dragging and deciding on the position, tap on Set wallpaper.
  • You will get to choose between “Home screen”, “Lock screen” and “Home screen and lock screen”.
Set Wallpaper in Android
Choose the appropriate option as you see fit. The setting to change the background is also available under Android Settings > Device > Display > Wallpaper > Google Now Launcher.

Changing Keyboard Themes

Speaking of cosmetic changes, if you use Google Keyboard and are bored of the same white layout, you can now change the colors so that you can add a bit more flavor to the keyboard app. It now has themes.

To access the option go to:

Android Settings > Personal > Languages & input > Virtual keyboard > Google keyboard > Theme

Set Keyboard Theme
In the Set Keyboard Theme screen, you can choose among various colors to suit your needs. There’s also an option to use your own image as a background for the keyboard. You can also set key borders if you want.
One of the new features in Android Nougat is the ability to input and save emergency information in your phone. This information can be accessed without unlocking the phone from the emergency dialer. You can save vital information like your name, address, blood type, allergies, medications, organ donor and medical notes. You can also store contacts so that they can be viewed directly.

To enter emergency information in Android Nougat:
  • Go to Android Settings.
  • Scroll down and under Device, tap on Users.
  • Tap on Emergency information.
You can enter the following fields in there:

Emergency information

Under Info
  • Name
  • Address
  • Blood Type
  • Allergies
  • Medications
  • Organ donor
  • Medical notes
Under Contacts

You can put in phone numbers and name from your contact list directly. Just press Add contact and then select someone. There can be more than one person on this list.

Accessing Emergency information

The point of entering the emergency information listed above is so that people can get it in case of a real emergency. So, say if your phone is locked with a security code or fingerprint and cannot be unlocked then still people can view it if they know where to look.
To access emergency information when the phone is locked:
  • Press the power button.
  • Drag your finger from bottom to top to bring up the emergency dialer.
  • Tap on the text that says Emergency.
  • Tap on the Emergency Information button twice.
Accessing Emergency Information
The information that you saved before shows up. Contact(s) is/are displayed on a separate tab but they cannot be dialed using the emergency dialer. There’s also an edit button but it requires you to unlock the phone first.
If you want to go under the hood and try some additional settings—more than what is available in the main Android’s settings menu—then there is System UI Tuner. It allows you to access some settings that haven’t been made mainstream by Google. You can tweak and customize the user interface which isn’t normally possible. But these are experimental features and can cause errors/crashes. They may disappear as well.
An example of a System UI Tuner Settings that made it to Android Nougat is editing quick setting tiles. Till Marshmallow it wasn’t available by default.

To Enable System UI Tuner

  • Pull down twice to access the Quick Setting menu from the top.
  • Tap and hold on the gear icon for a while and it will spin.
  • Let it go and you have successfully enabled System UI Tuner
You will be met with the following message:
Fun for some but not for all
System UI Tuner gives you extra ways to tweak and customize the Android user interface. These experimental features may change, break, or disappear in future releases. Proceed with caution.

Using System UI Tuner

Once turned on, you can access it anytime by going to: Android Settings > System > System UI Tuner.

System UI Tuner All Screenshots
  • Status bar: A list of items that you can display or hide in the status bar by using the slider next to them.
  • Do not disturb: Whether or not to show it with volume controls or use volume button shortcut.
  • Other: You can enable a special swipe-up gesture to turn on the split-screen feature.
  • Power notification controls: Once turned on, you can set 0 to 5 levels of notifications. These levels define in detail what is blocked and what is authorized.

To Disable System UI Tuner

If you no longer find any use for these special interface settings then you can:
  • Go to Android’s settings.
  • Scroll down to System and tap on System UI Tuner.
  • Tap on the three dots (options) and press Remove from Settings.
  • Confirm your action.
Android Nougat comes with a built-in feature that allows you to modify the tiles or items that are present in the quick settings drawer. This drawer is accessible by dragging twice from the top or using two fingers to drag the notification region. The tiles in this area can be sorted, removed and new ones can be added. Previously in Android Marshmallow, you could do it but with the help of System UI Tuner. Now, the feature is natively available without any digging. You must have noticed it already.

If you are not sure how to modify items present in quick settings in Android Nougat, try these steps:
  • Pull up the settings from the top. A mini-setting comes up first so pull it down twice.
  • Click on Edit.
Editing Quick Setting Tiles

You can simply long press and drag the tiles to add or remove them. Drag them toward the top to add them and drag them and put them in the bottom region to remove them. You can also sort the tiles using the same method. If you put more than 9 tiles then, you will have two pages of quick settings which you can swap through by sliding your finger toward the left on the quick settings menu.

Data Saver

While we are on the subject, you must have noticed a Data Saver setting there. It’s a new thing introduced in Android Nougat and is useful to prevent apps from using background data. Tap it once, see it light up and you will know that data saver mode is on. When this mode is on, only the app on the foreground will be given access to your precious mobile data. The ones in the background cannot connect to the internet and download stuff. They will be restricted from spending your limited GBs.

Giving Selected Apps Unrestricted Access to Data

If you long press the data saver quick setting tile and tap on data saver option or go to Android Settings > Data Usage > Data saver, you can see an option that says Unrestricted data access. Tap on it and a list of all your applications are displayed. Scroll through them and drag the slider next to them toward the right to give any application unrestricted access to mobile data.

Giving Selected Apps Unrestricted Access to Data

It will override the data saver mode and give the special app all the access it needs to connect to the internet.
Android Nougat has been released and it comes with a lot of goodies and behind the hood improvements. Two of the notable improvements that we can immediately use are the split-screen mode and the quick switch feature. These productivity hacks will save you a bit of time and trouble when using your phone.

Without wasting any time,
  • To use Split-screen: Long press on the menu button when an app is running.
  • To use Quick Switch: Double tap the menu button when there are background apps running.
The menu button is the one that you have been using to bring the list of your recent apps.
For those who need it, here are some additional details:


Split screen is a new and highly requested feature in Android devices. If your device is lucky enough to get the upgrade or if your phone comes with it, then you can use two apps at the same time. They share the screen (Top/bottom or Left/Right) and you can change how much real estate each application gets. Using this feature, you can take notes in your Google Keep while looking at your Google Chrome browser.

Using Two Apps Simultaneously

To turn on split screen: Long press the menu or the options button when any application is open. You will see the icon changing from a square to two rectangles (like the square has been divided into two). The app that you were currently using will be forced towards the top half or the left side of the screen. The new space created will list your recent apps which you can switch into. You can drag the splitter or the line in the middle to change the ratio of the screen that each application gets.

Once the split screen feature is activated, it stays on. When you go back to your home and open up new apps, you will see how it will be assigned a space on the bottom or right. Your last app seems to get the top or space in the left.

To turn off the split screen feature: You can long press on the menu button when two apps are open and when you are not in your home screen. You can also drag the splitting line to the extreme left, right, top or bottom to quit the split screen mode.

Quick Switch

Quick switch is simple to use but really comes in handy. Just double tap the options or menu button (the square one). You will notice that the currently active application is minimized and the last one is brought up on the screen.

For example: You were using the Play Store and then you opened up Google Chrome. If you double tap on the menu button, the Play Store comes back again. If you do it on the home screen, then it brings the app that you used before going back to the main screen. It is really quick and is capable of saving us some time.

Combo (Split Screen + Quick Switch)

When the split screen feature is on, if you double tap on the options menu and try to use the quick switch feature, the app on the bottom or right will switch to the most recent one.
If you want to backup the text messages that you have received in your Viber app then there are two ways to do so. You can either use the Email message history feature that creates a backup file and allows you to email it to yourself as a compressed zip file. You can also back up the message history to your Google Drive which can be restored later of you decide to reinstall Viber.

These features are useful because the application doesn’t store your messages in a centralized server and you may lose them when there is a circumstance that requires you to remove the app and re-install it in your device. You don’t want to lose your important text communication forever, do you?

How to Back up Viber Messages

So here are two ways to backup your Viber messages:

Method 1: Email message history

  • In the Viber app, access the options and tap on Settings.
  • Tap on Calls and messages.
  • Tap on Email message history.
Email Message History

It may take some time and the screen will just say Creating Backup File… Once the compressed file (Viber messages.zip) is generated, you can email it to yourself. Extract it and you will find all your chat messages saved as a .csv file.

Method 2: Backup to Google Drive

  • Go to Settings and then tap on Viber Backup.
  • Tap on the Settings link, select your Google account and give the application the permission to access your Google Drive.
  • Now you can tap on Back up on the same screen to save everything.
  • You can also Restore it to get everything back.
Viber Backups

This feature is especially useful if you change phones or have to re-install Viber. Remember, that these processes only save your texts and not your images, videos, audio/voices or contact pictures.
Viber has a Push-to-Talk (or rather Hold & Talk) feature that allows us to tap, talk and send short voice messages of up to 30 seconds to our contacts. If you haven’t used it then the feature is accessed by pressing the microphone icon present in the bottom right corner of the app. If you want to save the voice messages sent by your contacts to you then you will have to apply this special hack and you will require a computer to do so.

In Viber, you can easily share your photos, videos and send voice messages but it seems that only photos and videos are automatically saved in your device. Voice messages are saved but they are stored in a different format that no audio player I know of can play and they can’t be converted to a playable format either. The raw audio files are accessed by using a file manager and going to:

  • You need to enable you file manager to Show hidden files to view and access the .ptt folder.
  • You will find numbered files which aren’t playable by media players.

The Alternative Save Viber Voice Message Hack

The only possible way right now to save those voice messages is by actually playing and recording them using an audio recorder. Your computer is your best friend when it comes to doing this recording job. You can use free audio recording and mixing programs like Audacity to capture the audio coming in from your system while excluding the external audio from your microphone. Since you are going to use a PC, you will also need to install and authorize Viber for Windows PC or Viber for Mac.

Once you have the necessary software downloaded, installed and logged in, follow these steps:
  • Define the audio recording source in Audacity as Playback.
  • Click the record button.
  • Play the voice message in Viber desktop.
  • Clip out the blank parts by highlighting and pressing delete.
  • Save the recording by exporting from File > Export Audio.
Here's a screenshot from Audacity highlighting the steps above:

If you use Viber for communication, then you might have notice that you along with your contacts can set a picture for your display. It will be shown in Viber chats and while making calls as well. On your end, those photos can be uploaded from your phone’s gallery or a new picture can also be taken and you can also import it directly from Facebook. Your contacts also set their profile picture using these different methods.

If you are looking to save the contact profile pictures of Viber, then you can take the screenshots of their profile screen and crop out the remaining part. But that is counterproductive. What would be better is to access those photos of your contacts which are stored in your device. Yes, Viber uses your local storage to save those pictures and they seem to be permanently stored. To access the locally stored profile photos of contacts by Viber:
  • Use a File Manager to browse your local storage.
  • Navigate to /viber/media/User photos.
User Photos in Viber
You will find all the user photos in the folder. They are all of 720px X 720px square sizes. They will have complicated and totally randomized file names. It is simpler to identify them using the thumbnails. Note that these photos are separate from the photos and media that you share while chatting. Those are directly stored in your gallery. While browsing the folders, as shown above, you might have noticed the folders for them as Viber Images and Viber Videos.
