# Log Mobile Screenshot

The **Log Mobile Screenshot** block captures a screenshot from the mobile device during test execution.

It can optionally delay before capture, add a message to the log for context, and include custom key-value text fields. The captured image is available in PNG format and can be passed to other blocks that support screenshots.

**Note:** The screenshot on this page uses the **Elegance Design**, introduced in **2025.3**. If you are using an earlier version, your layout may look different.

## Quick-start

1. Drag **Log Mobile Screenshot** onto the canvas.
2. Specify the basic parameters required for this block to operate: **Image File, Wait, Message, Text fields**.
3. Run the flow when it’s ready.

## Building block parameters

### Parameters

- **Block header**: The green input connector triggers the block to start executing. The green output connector triggers when a screenshot has been successfully taken. You can rename the block title (“Log Mobile Screenshot”) by double-clicking it and typing in a new title.

- **Image File:** Provides an output containing the captured screenshot in PNG format.
  
  _Values:_ Image (PNG format)  
  **Notes:** Can be used as input in other image-processing blocks.

- **Wait**  
  Delays the execution of the block for a specific period of time.  
  _Values:_ Number (seconds)

- **Message**  
  Allows you to add a custom text message (up to 250 characters) to the log entry along with the screenshot.  
  _Values:_ Plain text or token  
  **Notes:** Optional field. Hidden in collapsed view to reduce clutter. Has input and output connectors for dynamic use. _Available from 2025.3.0 onward._

- **Text fields**  
  Adds custom key-value fields to the block. These fields can pass external or dynamic values into properties.  
  _Values:_ Dynamically added fields (click **Add field** to create)  
  **Notes:**  
  - Right-click inside a supported field (e.g., Message) and select **Insert token** to use a text field value.
  - Fields can be renamed by double-clicking on them. All tokens using that field will update automatically.
  - Useful for injecting context-specific data or variables into the block during runtime.
