Zello Android User's Guide

Updated October 19, 2018 

WELCOME TO ZELLO!

We try to make Zello as intuitive as possible so no instructions are needed to use it, but for those of you who like reading "how-to" manuals, this user's guide is a great way to learn about Zello's features. These instructions are valid for Android devices running Android OS 4.0.3 and above. 

This user guide is separated into 2 sections. If you only want to talk one-to-one with personal contacts or with groups of people you already know, you only need to use SECTION 1 tasks.

If you also want to meet new people, add and join existing Zello channels, or create your own channel, read SECTION 2 tasks as well.

Click on any task to jump to that section:

SECTION 1: USER ACCOUNT TASKS

SECTION 2: CHANNEL TASKS

 

ZELLO ICONS 

The following icons are used throughout the Zello user interface. This legend explains each icon's meaning:

 

SECTION 1: USER ACCOUNT TASKS

Installing Zello

Adding contacts

Now let’s fill up your Contacts list. Tap the CONTACTS tab, and then the Add Contact icon at lower right corner. The Add a contact screen displays.

Screenshot_20181005-213201.png

You have three ways to add a contact:

  1. Search
  2. Address book 
  3. QR Code Scanner. 

Using Search to find and add contacts already on Zello

If using the search field, enter a Zello username, email, or phone number into the search field and tap the Search icon (looking glass). If the user is not found, you can send an invite by email or text message. If the user has a Zello account, tap the username and Zello sends a connection request.

Until contacts approve your request, they will show as “Requesting authorization" in your Contacts list. As soon as your friends go online, they will see a notification of a Contact request with options to either Accept, Decline, or permanently Block your request. If they agree to accept your invite, their status will change to Available or Busy.

Using the Address Book to add contacts who are not Zello users

If the contact is not a current Zello user, you can add them from your Address Book.

Tap Address Book to see two tabs:

  • All contacts: Opens your Android address book.
  • Contacts on Zello: Lists contacts from your address book with Zello accounts.

Tap the names of the people you want to add or invite to Zello, then tap IMPORT.

For contacts with Zello accounts, Zello sends them a connection request. After they agree to connect, they will appear in your Contacts list.

For contacts who don’t have a Zello account, a dialog box displays options for sending an invitation. Select your preferred option. Zello creates a message with all the information filled in for you, but you can edit the message to your heart’s content. Happy? Tap Send to email the invite.

Using QR codes to add contacts

Scanning a contact's QR code is the fastest way to add a contact. The QR code is located at the bottom left corner of the user's profile picture. From the Add a contact screen, tap on QR Code Scanner. Focus the green scanner box on the QR code until it is read in. The contact is automatically added to your CONTACTS list. 

How to Accept, Decline, or Block contact invitations 

A pending invite from another user is indicated by a red circle marker and "Requesting authorization" notice in your CONTACTS list.   

Press and hold on the user's invite to see a pop-up, where you can Accept, Decline or permanently Block this user's invitation.  

Screenshot_20181011-164631.png

Talking to contacts

When your contacts appear online and has a Status of Available, you can contact and talk to them. Select the username, press and hold the push-to-talk button until solid red while talking. Release the button when you finish talking.

Screenshot_20181011-164743.png

If the person is Available (solid green circle), you should get a reply soon. When someone is Busy (orange circle), Zello saves your message in their history for later listening. If a contact shows Standby (empty green circle), it means the user doesn't have the app running at the moment or connection has been lost, but you still can send offline messages to the contact. When the connection is restored, any missed messages wlll play automatically. 

Sending texts, call alerts, images, and locations

You can send texts, call alerts, images, and locations to your contacts from the Main Screen:

  1. Tap CONTACTS
  2. Press and hold on name of contact to display the pop-up menuScreenshot_20181011-164823.png
  3. From the pop-up menu, select the action you want to take.

Deleting a contact

To delete a contact, press and hold the name of the contact in your CONTACTS list to display the pop-up menu, then tap Delete contact.

Sending call alerts to contacts

You can send alert tones and text messages to a contact. The receiver will hear an audio tone or feel a vibration that repeats every minute until the person accepts or dismisses the alert. You can add a text message or links.

To send a call alert, tap the Call Alert icon (bell) from a contact's talk screen and enter optional text. When done, select SEND. You can also long press on the Call alert icon to send a default message of "Zello me!" instantly. 

Screenshot_20181013-182511__1_.png

Changing your status

To change your status, tap the Menu icon and then Status 

When your status is Available, all incoming messages play in real time. Messages are also saved in History or you can press the Replay icon to play back instantly. 

When you change your status to Busy, incoming messages are not played real time, but are instead saved to History. You will receive a vibrate alert and missed message marker in the Notifications bar when a message is received. You can listen to the message at a more convenient time.  

Solo status is used when you want to talk to only one contact, muting other contacts or channels that may be transmitting at the same time.  You can then go into the History to hear any missed messages. 

When you set Status to Offline, Zello does not save any new messages. It retains the messages you already have prior to going Offline. After going Offline, contacts will initially see you in Standby mode (empty green circle) and they can still send you offline messages for up to a week. If you don’t use Zello for one week or longer, it will automatically change your status to Offline, and you will not receive offline messages. 

You can customize a message for others to see when you’re Busy. To do this, tap Set status message and enter the message.

SECTION 2: CHANNEL TASKS 

Channels are unique to Zello....Channels are real-time talk groups which can run 24/7, similar to radio stations. Channels can be private or public, for people you know, or people you want to know, from all corners of the world. Tens of thousands of channels already exist on Zello. Join in the conversations or make your own channel in minutes.  

Adding channels to the Channels list

There are three ways to add existing channels to your Channels list:

The three methods are described in more detail next. 

Using trending lists to add channels 

You can use Zello to talk to your friends privately or join one of many public Zello channels. You might start with Trending Channels, which are the most active public channels at any given time. To display the Trending Channels lists:

1. Tap on CHANNELS icon. 

Screenshot_20181011-165055.png
 
2.  Tap on Add Channel icon at lower right corner
 
Screenshot_20181011-165105.png
 
3.  Select Trending channels to display lists for Filtered pre-approved channels for general audiences or All channels which includes Filtered and 18+ channels.  
 
Screenshot_20181011-165117.png
 
4. Tap on the channel name to see the channel profile and tap +ADD at upper right corner if you want to save it to your CHANNELS list. Connect to the channel by tapping the Power icon until blue to listen and talk in the channel. 
 
Tap the power icon until gray to disconnect from the channel and stop receiving messages. If you want to stay connected but mute the channel, tap on the Pull-down menu and select option to Mute the channel. 
 

Searching for channels to add

You can search for channels by using keywords, topics, or a specific name:

  1. On the Main Screen, tap CHANNELS
  2. Tap the Add Channel icon in the lower right corner
  3. Tap Find a channel
  4. Enter the name or keyword for a channel to search on
  5. Tap the Search icon
  6. See the channel you want?  Tap on the name and then tap +ADD to add the channel to your Channels list.

Scanning QR codes to add channels

The fastest way to add a channel is by scanning the QR code which looks similar to the image below. The channel QR code is located on the bottom left of the channel's profile picture. 

Screenshot_20181013-191621.png

To scan a QR code and add a channel:

  1. From the Main Menu, tap CHANNELS 
  2. Tap the Add Channel icon in the lower right corner
  3. Tap Scan QR code
  4. Focus the green scanner box on the QR code until it's focused and is read in
  5. Once read into your device, the channel is automatically added to your Channels list.

Talking in a channel

To talk in the channel, make sure you are connected (Power icon is blue) and then push and hold the big button until solid red to talk. As long as no one else is trying to talk, you can talk as long as you want. If other users are trying to talk, the talk time before interruption is set by the owner in the channel profile (1 second to 10 minutes). 

Using Solo Status 

When you’re connected to multiple channels, you’ll hear every conversation for all active channels, which can become rather confusing. You can set your Status to Solo (solid blue circle) to talk to a single contact, while silencing other contacts and channels. Missed messages from silenced contacts and channels can be replayed in History. 

  1. On Main Screen, select Menu icon at upper right corner
  2. Tap Status 
  3. Select Solo status 

Screenshot_20181011-170314.png

 

Muting a channel

If you want to mute all channels and contacts, you should change your Status to Busy. However, if you only want specific channels to be muted, tap the Pull-down menu on the channel's talk screen and select the Mute channel option. All missed messages will be sent to the channel's History and can be replayed at a later time. 

Sending texts, images, and location to the channel 

If the owner of the channel has enabled texting, images, and location sharing, you can perform these tasks from the History/Conversation screen. 

From the channel talk screen:

  1. Tap on the History/Conversation icon at top
  2. On the History screen, the text field displays at the bottom, with the Share Image icon to the right
  3. To share your location, tap on the Pull-down menu and select Send location.

Screenshot_20181014-164028.png

Creating your own channel 

You can create your own channel to talk about an interest, activities, or any topic as long it complies with our Community Guidelines. Once created, you become the "owner" of the channel. Contacts who join your channel are "subscribers". The number of subscribers allowed per channel is unlimited, but there is a maximum of 3500 who can be online and active at any given time. Channels are permanent until deleted by the owner.  For more information about Channels, see Channel Quick Start Guide.

Follow these steps to create a channel.

  1. On main screen, tap CHANNELS
  2. Tap Add a channel icon at bottom right corner
  3. Tap Create a new channel
  4. Enter a name for the channel. Try to make the name easy to remember and search for  
  5. Enter a description of the channel. If you want to make it easier for people to find your channel and stay on topic, ensure the description explains the topic of the channel and includes related keywords
  6. Select the channel type you want. This setting is important because it determines how private and secure your channel is. The least private type is OPEN, followed by Zelect and Zelect+ which require users to be "trusted" by mods and admins in order to listen and/or talk. Zellocast type is a listen-only channel, where only mods and admins can talk; everyone can listen. For information on the 4 channel types, see FAQ for Channel Types
  7. Decide whether to add a password to access the channel. This will prevent unauthorized users from hearing or talking in the channel. To set a password, tap Require password and enter a password in the box that appears 
  8. Fill in any optional fields, enable texting, image sharing, or location sharing if desired
  9. Mark your channel as 18+ if content is not suitable for kids or general audience. Select to Promote if you want your channel to display on public Trending lists
  10. To authenticate a user's identity before joining your channel, turn on Require verified email and/or Require verified phone number options.

Adding channel Admins/Mods and managing subscribers

A well-moderated channel attracts more subscribers. Owners can assign Admins and Mods to help moderate channel activity by removing disruptive users and pre-screening users in Zelect and Zelect+ type channels.

There are two ways to add Admins and Mods and manage online subscribers: from the History/Conversation screen or by using the Users list. 

From the History screen: 

If the user sent a message to the channel is still listed in the History, press and hold on the username to see options to Block, Prohibit talking, Bounce, Revoke trusted status, Make moderator, Make administrator, or Mute. 

From the Users list: 

If the user is not displayed on the History screen, use the Users list to find and manage the user. The user must be online and connected to the channel to be displayed:

On the channel talk screen, tap the Users icon at top to display a list of online subscribers.

From the pull-down screen, select from the list of options to manage the user on the channel: Block, Prohibit talking, Bounce, Revoke trusted status, Make moderator, Make administrator, or Mute.

  • Block is a permanent or timed temporary block from the channel
  • Prohibit talking is a timed block
  • Bounce is a temporary removal, the user can rejoin immediately
  • Revoke trusted status removes user from a Zelect or Zelect+ channel 
  • Make moderator gives user the ability to manage other subscribers. Mods can block, Prohibit talking, Bounce, and Revoke trusted status. 
  • Make administrator gives user the ability to manage subscribers and make certain changes to channel settings, such as changing the profile picture, description, and talk interval times. 
  • Mute to turn off user's audio.

Managing blocked or trusted users, Admins and Mods

You can easily manage moderators, adminstrators and blocked or trusted users by tapping on the channel profile picture to open the channel profile. There, you will see lists for blocked users, users prohibited from talking, trusted users, moderators, and administrators. Select a list and tap on the user's profile picture or long press on the username to manage the account.
