View and manage devices

The DEVICE LAB menu, provides visibility and control of devices and connectors in the mobile lab.

Note: When preparing a test, you should select your device through your testing tool interface, such as UFT or TruClient. For details, see Mobile Center Wizard or Record scripts.

Device display

Click DEVICE LAB>DEVICES to display the devices in the Lab.

  • Administrators will see all the devices that have been connected to Mobile Center. An admin user will also have full control over the devices and the workspaces to which they belong.
  • Users will see all of Mobile Center's shared devices (devices in the public workspace), as well as devices in workspaces to which they have been given access.

Tip: If you installed the connector in private mode and your device was then shared, you can re-assign the device for your own use only by disconnecting it and then plugging it back in.

The following details are displayed in the Devices page and device card:

  • License capacity. This the number of devices that can be accessed concurrently. For more, see License management.

  • Number of devices. The number of devices that match the current filter, out of the total number of connected devices.
  • Operating System and version.
  • Device name. Click the name to edit it. The default is the model number of the device.
  • Manufacturer and Model name.
  • Workspace name. The workspace to which the device is assigned.
  • Connector latency. When you hover over the latency icon , Mobile Center shows the connector's latency. This is the latency between the client and the connector to which the device is connected, for example Remote view latency: 18 ms. For optimal remote screen viewer performance, select a device with good latency. The latency is considered good if it is less than 100 ms (green), mediocre if it ranges between 100 and 200 ms (yellow), poor if it ranges between 200 and 300 ms (red), and bad if it exceeds 300 ms (gray).

    Note: The latency display is not supported for Internet Explorer or Edge browsers.

  • Reservations. The reservations for the device. For example, Available or Reserved by... Until. Click this section to view and create reservations. A triangular emblem at the bottom right of the device indicates its status:

    Reserved for you
    Reserved and in use by you
    Reserved for someone else
    Reserved and in use by someone else
  • Emulator. This indicates that the device is being connected through an emulator. You can use the Features filter to filter by physical or emulated devices.

You can also view the devices in a list. Click the List and Card view buttons in the upper right corner to toggle between the views. To see the details in List view, select a device and click More.

Note:  To use iOS devices with Mobile Center you must re-sign the Agent apps with a development certificate of an Apple Developer account. For more details, see Re-sign the Agent apps.

Device management

When you hover over a specific device, the following options are displayed (The only option available for Amazon WS devices is Unlock device):

Open device remotely. For Available or Reserved for me devices, access the device remotely. This reserves the device for 30 minutes or uses an existing reservation, allowing you to interact with the device and conduct exploratory testing.

If the device is in the Reserved and In Use By Me state, the interaction with the device in the remote session will be limited and most options in the control panel will not be available. However, this option is useful for when you want to remotely connect to a device while an unattended test (such as an Appium test) is running. If the device is Reserved for or In use by others, or if you do not have the adequate license capacity, this button will be disabled.

When you are finished working with the device, click the Close button in the top right-hand corner of the remote window to close the session and delete the device reservation.

For information about exploratory testing and interacting with the device, see Device control panel.


  • Parallel remote sessions on the same device are not supported.
  • If you have many tabs (60+) open in your native mobile browser, the remote view may be unresponsive.

Remove device. Remove a Disconnected device. To remove a device with another status, it must first be disconnected from Mobile Center.

Unlock device. Release a device that is locked.
For example, if a device was not automatically unlocked when the test finished, or if a specific device is required by another tester for performing some urgent validation of an app on a specific device model, the administrator may need to unlock a device.

More Information: Opens the Device Information window.

The top section contains general information about the device: its ID, name, network connectivity level, workspace, whether Capturing audio is enabled, and availability.

This window has three tabs:

  • Details. The URL of the device in remote view, and other device information such as the agent version, connector, storage, OS, and so forth.

    Tip: Using the device's URL string, you can share a specific device with your testers. This allows them to access the device directly without having to open the Mobile Center lab and manually navigate to the device.

  • Reservations. A list of current reservations for the device, and an option to create a new reservation.
  • Actions. Interact with the device:

    • Restart device: For an admin user, restarts all devices, including devices that are in use. For non-admin users this action is only enabled for available devices, or devices reserved for or in use by you. Windows phone devices and emulators cannot be restarted.
    • Reconnect device: Re-launch the agent on the device. If this does not succeed, you may need to access the actual device.

Tip: You can also access the Device Information window by clicking the lower section of a device card (for example, where it says "Available").

View and manage connectors

Click DEVICE LAB > CONNECTORS to see a list of all of the connectors and their properties. The grid displays the connector details such as its name and version, status, the machine hosting the connector, and the number of connected devices. Admin users can view all the connectors connected to the Mobile Center server. Non-admin users can view only their own connectors.

To add a new connector, click . Follow the instructions in the dialog boxes and wizards. For more details on installing connectors, see Install the connector on a Windows machine, Install the connector on a Linux machine or Install the connector on a Mac machine.

Sign and distribute iOS Agent apps

The Agent, Agent Launcher, and WebDriverAgent Runner apps need to be installed on each device that you want to use with Mobile Center. These apps must be re-signed with a development certificate of an Apple Developer account, and a development provisioning profile belonging to the same account. These provide the identity of the developer, and the list of devices on which distribution of the app is allowed.

Admin users can set up Mobile Center to automatically re-sign these apps and distribute them to all connectors. When devices are connected to a connector, the re-signed apps are automatically installed on the devices.

When working with many devices and workspaces, you may need to use different signing services for your devices. For example, in certain iOS environments you can only sign up to 100 devices. For details on how to add signing services, see Multiple packaging services.

The Connectors list action buttons let you:

  • Reconnect Devices, a step required after the Agent app distribution status is complete. Select multiple rows to perform this action on several connectors at once.
  • Remove a connector from the list. This can only be done for a disconnected connector. The button only removes the connector from the list of connectors; it does not delete the physical connector installed on a remote machine. When a connector that has been removed is restarted, it will be displayed again in the grid.

Tip: You can select multiple connectors and apply the actions to all of the selected connectors.

To automatically sign and distribute agents:

  1. Set up the iOS packaging service. Make sure that you have set the properties for the packaging service and specified any additional packaging services, on the Administration settings page.
  2. Click DEVICE LAB > CONNECTORS. This section is only visible to admin users.
  3. Click START. The resigning and distribution will begin, affecting all connectors.
  4. When the distribution is complete, click UPDATE. In the list of connector details (shown above), you can see the latest distribution status of the re-signed Agent apps to the connector.
  5. When the distribution status is complete, you need to reconnect the devices with the updated packager. Do one of the following:
    • Select the relevant connectors in the grid, and click Reconnect devices.
    • From the Lab console, restart the iOS devices associated with that connector.
    • Physically disconnect and reconnect the devices.
    The new Agent apps will be copied from the connector to the connected devices.
  6. To view the devices associated with a specific connector, click the X Devices link in the row of the desired connector. The Devices view opens with the devices filtered for the selected connector.

Note: These capabilities are only available for Trial, Ultimate, and Enterprise licenses.

View and manage device reservations

Click DEVICE LAB > RESERVATIONS to view and manage reservations for a device. This page also provides details about the current reservations: Running Now, Coming Up (next 24 hours), and Future Reservations. By hovering over a reservation, you can edit or delete it. Admin users can toggle between Mine and All reservations.

You can make a reservation for a specific device, provided that you have access to the workspace. Your administrator can set up workspaces and assign you to one or more of them.

For a new reservation, click to open the Create Reservation window. Once you reserve a device, it will be locked for you at that time.

Here are some guidelines to remember:

  • You can specify an end time for your reservation, an open-ended reservation with no end time, or a reservation until the end of the test.
  • By default, reservations are active for 30 minutes and extendable for 5 minute intervals. Your administrator can modify these values or edit specific reservations.
  • After you reserve a device, the Reservations page indicates that you reserved it, and shows the start and end times.

A triangular emblem at the bottom right of the device indicates its status. For details, see Device display - Reservations.
