B20 Overview
Setting up your device
Follow these step-by-step instructions to set up your B20. Power off the phone before inserting any cards!
1 Remove SIM Tray
Remove the SIM tray by inserting a pin eject key/paperclip in the small circular hole at the bottom of the tray. The tray will then eject from the phone.
2 Configuration 1: Dual SIM Standby
Orient SIM card to match layout on tray. SIM 1 (Nano) supports 5G connections. SIM 2 (Nano) supports 5G connections.
3 Configuration 2: microSD™ Card
Orient microSD card to match layout on tray. microSD card supports up to 512GB
4 Replace SIM Tray
After placing the SIMs and/or memory card in the tray, slide it back into its slot. It will
5 click and hold in place.
Plug in the type C connector to charge the phone or transfer data.
Warning:
SIM cards are small enough to become a choking hazard, so please keep them away from children & pets. SIM cards are also quite delicate. Please be careful when handling your card.
Setting up your device - cont.
Welcome Screen: Tap on the white arrow to select your language and then tap Start.
Connect to Wifi: If you are in range of a trusted Wifi network, configure and connect here. Tap the name of your Wifi network, enter the password and tap Connect.
Checking for updates: Once connected to a network, the phone will check for any system updates and prompt you to update if necessary.
Copy apps & data: You can transfer apps, photos and music from a previous Android device or the cloud. If you choose this option you will be prompted to either use your old phone to copy data wirelessly, or sign into your Google account and restore from a cloud backup. You can also choose to set-up as a new device and start with a clean slate.
Google account: In these next screens, you have the option of skipping them entirely or filling out your Google account credentials, or even making a new Google account if you've never had one. Regardless you will at some point need a Google account, as they are necessary to use the Play Store and get apps and app updates. You will also need to accept Google's Terms of Service during this portion of the setup.
Protect your phone: Now is the time to prevent others from using this phone without your permission by activating device protection features. You can set up a pattern, PIN, or password unlock code. You can also skip this and add protection later. Remember that if you set-up device protection but later forget your unlock code, the only way to access the phone will be by performing a factory reset which will delete all device data.
Controls and Using the Touchscreen
"Tap": In some documentation, this may also be referred to as a "touch" or even a "click". It's almost exactly like tapping your finger on a table; aim a single fingertip, touch it to the screen, and pull it away from the screen. You can have your finger in contact with the screen for quite a bit before the phone registers it as a "long-press", so don't feel like you have to pull away instantly.
"Double-tap": Two taps in rapid succession, almost exactly like double-clicking a mouse, but with your fingertip. Rarely called a "double-click". Used for different things in different apps, so make sure to consult the help for that app!
"Long-press": Sometimes referred to as "hold" or "tap-and-hold" or "touch-and-hold". Place your finger on the screen and keep it there. After about a full second, the phone will recognize this as a long-press and give you some kind of feedback: a menu might appear, an icon might start shaking, or some element of the interface will change to indicate that you have the phone's complete attention. What makes the long-press a little difficult is that in some apps, removing your finger from the screen makes your next selection, and in other apps, you're expected to make a separate "tap" to select the thing you want after a long-press. This behavior isn't constant across all apps so you'll need to experiment a little with your apps. While your smartphone certainly has a number of buttons you can push, you will control it primarily by using the touchscreen. You may wonder just how many different ways one can touch a screen, and as it turns out there are a few of them! You'll find a handy list of the most common ones below, which includes the name for the gesture and a description how to perform it. Important!: Your phone's touchscreen is NOT pressure-sensitive, as it instead works by sensing tiny electrical currents. This means that when you touch the screen, you only need to make contact, you do not need to apply pressure. If your fingertips are heavily calloused (or if you are wearing non-conductive gloves), the screen may not register your touches properly. In that case, try a different fingertip or a patch of bare skin.
Controls and Using the Touchscreen
"Drag-and-drop": Sometimes mentioned a drag". First you long-press something, then once you've gotten the visual feedback that shows that the phone interpreted your long-press, you keep your finger on the screen as you move it around. When you remove your finger from the screen, you "drop" the item in question. The usual example is moving your app icons around. First you long-press the icon in question until you see it get "picked up" or highlighted somehow, then (keeping your finger on the screen) you "drag" the icon to its new spot. When you let go, you've "dropped" it. The key part is that a drag-and-drop always starts with a long-press.
"Slide": Closely related to the drag-and-drop. While a drag-and-drop requires a long-press at the beginning, a slide does not. Unlocking the phone, answering a call, and bringing up Google Now all require slide motions, where you slide an on-screen button in a straight line, with no pause or delay after touching the button.
"Swipe": A swipe is a gesture that's just like moving a playing card across a smooth felt table. There's no pause at either end, just a smooth motion. The tricky part of swiping is what is meant by the term "swipe left" or "swipe right"
Those Three Buttons
natural_image
Abstract gradient background with white geometric shapes (triangle, circle, square) on purple and white sides, no text or symbols present.Back Home Recent
Back: This does exactly what its name suggests; it takes you back one step. If you called up a sub-menu, for example, and wanted to go back to the previous menu, just tap the Back button one time to do that. If you tap Back enough times, you will eventually work all the way to your Home screen, so this is another way of getting back to familiar territory if you're lost.
Home: The Home button has two main functions. Tapping the Home button will always take you back to your Home screen, the "center" screen in the pages of icons you can have on your phone. If you're lost, tap Home and you'll be taken back to familiar territory! Long-pressing the Home button brings up the Google Assistant that can provide additional support.
Recent: Tapping this button brings up the "Recent" menu. This is a horizontal list of apps that are currently active. You can slide the list left or right to see the whole list. Slide an app's picture up to kill the app and make it inactive. This process is a useful thing to know as doing so can solve many problems
Common Onscreen Buttons
- Icon Drawer: This button is used to access a general
menu in a particular app. In Google Maps, for example, it
lets you switch between map and satellite view, among other things. In Gmail, the Drawer allows you to switch between folders. If your app has a Drawer button, you should familiarize yourself with the options it presents.
Icon Share: Pressing Share allows you to send the content of your current app to someone else. For example, when looking at the details for an app in the Play Store, using the Share button allows you to send a link to that app by e-mail, Bluetooth, MMS, or in a variety of other ways. The same thing can be done in the Contacts app and other places.
Icon Overflow: The official name is both Menu and Overflow, but NUU documentation uses Overflow to avoid confusion. This button brings up options relevant to the current screen. If you were looking at a Contact card, for example, Overflow would allow you to edit, delete, share, or set the ringtone for that contact only. Overflow provides access to your bookmarks and other settings in the Google Chrome app.
Icon Microphone: Used for Google Now, OK Google, and voice-recognition. Tap Microphone and then speak when prompted.
Icon Call: Dials the number entered on the keypad, or if you are looking at a contact page, dials the preferred number for that contact. Common Onscreen Buttons
Icon Locate: Most often found in mapping software, tapping this will center the map on your location if it was not already.
Icon Search: This magnifying-glass icon, when tapped, activates the search function for whatever app you are using.
Icon Send: Most often seen in e-mail apps, this sends the current message to its recipient.
Icon Trash: Destroys the currently selected item. There is usually no way to undo this, so be careful
Power On/Off, Wake Up, Unlock, Go to Sleep
Your phone can power on and power off fully, as discussed on the SIM card installation page. Here are those instructions again for reference.
On: Hold down the wake/sleep button for a few seconds. You will see the start-up screen when the phone powers on successfully. If a few seconds you will be taken to the unlock screen.
Off: Hold down the wake/sleep button for a few seconds. When you see the menu pop up, tap the "Power Off" option. Confirm the choice to power off the phone. Your phone can also go to sleep, and wake up from this sleep. Putting your phone to sleep saves battery power without the inconvenience of fully powering-off the phone.
Sleep: Tap the wake/sleep button once. The display turns off, but the phone remains on. Wake: Tap the wake/sleep button and the phone will wake up and show you the Lock Screen. Wake/Sleep Button
The Lock Screen shows up every time you wake your phone from sleep. To unlock it, slide the padlock icon straight up. You can directly access the assistant by sliding the microphone icon to the right, and you can access the camera by sliding the camera icon to the left.

This list can be customized and rearranged by tapping on the pencil logo.
You can also do screenshots by click the volume down and power button at the same time. That screenshot will go directly into your Photos.
Customize Your Home Screen
You can customize your home screen(s) by adding or rearranging application shortcuts, folders, customer wallpapers and more.
Adding an Application Shortcut: Swipe up on the All Apps Arrow to display the complete list of apps. Tap and hold on the app and start to drag it to the side. The home screen will appear, and you can place the app on the screen.
*This is a shortcut to the app, so you will notice that the app still remains in the list of All Apps.
Multiple Home Screens: You can have multiple home screens if you need quick access to many apps. In order to add a second home screen simply tap and hold on the app and then drag it to the far side of the screen and then place it on the second screen.
Rearranging or Removing an Application Shortcut: To move a shortcut to a different spot on the home screen tap and drag the shortcut to its new location. To remove a shortcut from the home screen tap and drag the app up to the X.
*Note this only removes the app shortcut, it does not uninstall the app.
Uninstalling an App: Same as removing a shortcut but drag the app to the trash can.
* Note that for some of the stock Google apps, there is no trash can because these apps cannot be uninstalled.
Creating a Folder Containing Multiple Application Shortcuts: Tap and drag one app onto a second app or folder and release.
Calling Place a Phone Call
First, start the Phone app. It's located on the main Home screen or can be accessed from All Apps. It can also be accessed from the Lock Screen by sliding the phone icon to the right. You can make a phone call from a list of your favorite, recent or all contacts. Tap on the corresponding icon to display that list, and simply tap on the contact to initiate the call Press the keypad icon to bring up a numeric keypad. Type the phone number you wish to dial and then press the call button which looks like a phone handset on a green circle.

Tap on the Start Chat button and then enter phone number or contact you are sending the message too. You can also choose to send to one of your contacts listed below by tapping on the contacts name.
Enter your message in the Text message field, and hit the Send arrow when finished
The Settings Menu
The settings menu is a complex but necessary part of your smartphone. It allows you to connect to wireless networks, manage the apps stored on your phone, and change your security settings just to name a few among many options.
You can find the settings menu by swiping up to display all apps and selecting settings. Once you have opened settings, take note of the search box across the top. You may use this to search for a setting; very handy for finding one that's buried several menus deep!
Read on for an item-by-item breakdown of each part!
