“Zoom” is a web conferencing tool that is widely used in the business scene.

Did you know that you can use it not only on your computer, but also on your smartphone or tablet?

Compared to conventional conferencing tools, it has the advantage of being easier to use than conventional conferencing tools, as you can hold meetings with your usual devices without the need for dedicated equipment.

Here is a summary of the functions installed in the smartphone version of the Zoom app and how to actually use it.

We also explain the causes of troubles such as not being able to hear the voice and how to deal with it, so please refer to it if you are planning to use it or if you are worried about troubles during use.

Functions that can be used with the smartphone app version of Zoom

The smartphone version of the Zoom app is compatible with iPad, iPhone, and Android smartphone models.

It is possible to exchange between PCs and smartphones, as well as between smartphones, and it is characterized by being able to use it regardless of the model.

First, let’s take a closer look at the functions that are installed in the smartphone version of Zoom.

Video recording of meeting content

Zoom allows you to record and record the contents of the meeting.

The recorded data can be saved on the cloud and can be played repeatedly later.

However, please note that cloud storage is a function for paid members only, so if you want to use it, you need to obtain a professional or higher license instead of the free version.

By recording the contents of the meeting, there are merits such as saving the trouble of creating minutes and making it easier to follow up on absentees.

The microphone that comes with your smartphone is sufficient, but if you want to improve the sound quality, you should install a dedicated microphone or speaker.

screen sharing

Zoom has a screen sharing function, and it can be used in the same way with the smartphone version application.

You can display the computer screen on the smartphone side, or vice versa, so it is convenient when giving operation instructions.

In addition to the screen, you can also share photos and files in storage such as Box, Dropbox, and Google Drive.

You can also use the whiteboard function to write pictures and letters freehand.

The whiteboard function is only for iPad and Android smartphones, but you can also view the shared screen on iPhone.

In addition, although it is limited to PCs and tablets, there is also a function to remotely operate the screen of the other party.

text chat

Zoom allows not only voice and video exchanges, but also text chat conversations.

You can use chat only, and you can also chat in parallel with the meeting.

You can send and receive messages to individual messages or Contacts and Channels . You can add contacts, create contact groups of specific members.

It’s convenient because you don’t need to launch a separate email app, such as when sending a notification when a meeting starts.

virtual background

The smartphone and PC versions of Zoom have a function that allows you to freely set the background during the meeting.

You can use an image registered in the Zoom app, or you can set your own image as the background.

Please use it when you do not want to see your whereabouts, such as remote work or telecommuting.

How to start a meeting from your smartphone

To use Zoom from your smartphone, you need to download and install a dedicated app.

From here, let’s take a closer look at how to install the Zoom app and how to actually use it.

App installation

Install and use the Zoom app from the store (App Store for iOS, Google Play for Android smartphones).

When you launch the app after installation, you will be prompted to choose between signing in or signing up.

Follow the instructions and enter your email address, account name, etc. to complete the registration.

When using from a smartphone, both the host and the participant of the meeting must install the app.

However, only the organizer needs to create an account, and participants can just install the app.

host a web conference

The procedure for hosting a meeting with the smartphone version of the Zoom app is as follows. (For iPhone)

  1. Tap “Send Invitation” on the “Meeting” page
  2. Select an invitation method from message, email, or URL copy
  3. Send an invitation message to the relevant member

If the other party is registered as a contact in Zoom, it is efficient to copy the URL and notify them from chat.

If you don’t know your Zoom account, let’s notify you using another email app.

Also, if you want to invite other people during the meeting, you can invite additional people from “Participants” at the bottom of the screen.

Join a web conference

If you want to join the Zoom meeting from your smartphone, you will need the invitation URL sent by the host.

With the Zoom app installed, tap the invitation URL to automatically move to the meeting screen.

If the app is not installed, it will move to the store, so let’s install it first.

schedule a meeting

If you want to schedule a meeting for a specific date, here are the steps: (For iPhone)

  1. Tap “Schedule” on the “Home” page
  2. Set the meeting name, schedule, password, etc.
  3. Tap “Done”

After setting the schedule, notify the participants of the issued URL.

Causes and solutions when calls on Zoom do not work

Zoom is a tool that allows you to hold online meetings using existing devices such as computers and smartphones.

Text chat is also available, but the main function is voice and video call function.

However, depending on the settings of the smartphone, there are cases where your voice does not reach the other party, or on the contrary, you cannot hear the other party’s voice.

Finally, we will explain the causes and solutions when you cannot hear the audio while using Zoom.

My voice does not reach the other party

There are two main reasons why your voice does not reach the other party on the smartphone version of Zoom.

  • Audio is muted in app settings
  • The use of the microphone is not permitted in the settings of the smartphone

If the audio is muted in the Zoom settings, tapping “Mute” at the bottom of the meeting screen will improve it.

If you are not able to use the microphone on your smartphone, allow the use of the microphone on Zoom from the smartphone settings screen before joining the meeting.

I can’t hear the other party

If you cannot hear the other party’s voice, the possible causes are as follows.

  • The other party is using the wrong mute or microphone settings
  • Before using Zoom, I was using a camera app, etc.

It is possible that there is a problem with the settings on the other party’s side, so let’s have them check whether mute settings and microphone permissions are set.

Also, if you are using a camera app, etc., and you start Zoom without exiting, it seems that you can not hear the sound.

It may be improved by closing unnecessary apps and then starting Zoom.


  • The smartphone version of Zoom can also use the same functions as the computer version, such as recording and screen sharing.
  • The meeting can be started simply by issuing an invitation URL from the Zoom app and notifying it
  • If you can’t hear or hear the sound, check the mute settings and the microphone settings on your smartphone.

Zoom is a convenient service that can be used on smartphones and tablets with the same performance as a computer.

It is also useful for improving work efficiency and promoting smooth communication, so please consider using it.
