Only administrators can manage devices.

The **Venzeo™ Mobile App & Devices** page lists every active phone and tablet with the Venzeo™ mobile app in your organisation. Deactivated devices are not listed.

## Check how many devices are active

Open the main menu, expand **Venzeo™ Mobile App & Devices** and choose **Manage devices with Venzeo™ mobile app**. Three figures summarise your devices:

- **Active devices with activated Venzeo™ mobile app**: the devices that can create reports now.
- **Max. devices with Venzeo™ mobile app included in the license**: how many active devices your licence allows.
- **Devices with up to date mobile app:**: the share of devices on the latest app version. To update the others, see [Updating the Venzeo mobile app](https://help.venzeo.com/en/article/update-venzeo-mobile-app).

## Find a device

1. Open the main menu, expand **Venzeo™ Mobile App & Devices** and choose **Manage devices with Venzeo™ mobile app**.
2. In the device table, open the filter of a column, for example **User name**, **App Version** or **Last Report Date**.
3. Enter or pick the value you are looking for. The table now shows only the matching devices.
4. Optional: Click **Download to Excel** to save the listed devices as an Excel file.

## Change a device's user, phone number or note

1. Open the main menu, expand **Venzeo™ Mobile App & Devices** and choose **Manage devices with Venzeo™ mobile app**.
2. In the device table, click **Edit** next to the device. The **Editing device** pop-up opens, with the **Device ID** in its title.
3. Under **Assigned user**, choose **Existing one** and pick the person, or choose **New user** and enter their **User name**. This name appears on every report sent from the device.
4. Optional: For a new user, pick their **User's Groups**. This field appears only when your organisation uses groups.
5. Under **Phone Numbers**, choose **Device with phone number (has SIM card or eSIM)** and enter the number, or choose **Device without phone number**.
6. Optional: Enter a **Note**, for example the vehicle the device belongs to. Only people who use the web interface see the note.
7. Optional: Enter an **Area**, such as a city or depot. This field appears only when your organisation uses areas.
8. Click **Save**. The pop-up closes, you see **Successfully saved**, and the table shows the new details.

The **Model** and **App Version** fields in the pop-up are read-only.
