# Device Type

You can customize how the Headless Browser emulates different device types by using the `?p_device` parameter. This allows you to emulate fingerprints of the selected device types (desktop, mobile, tablet), which is particularly useful for scraping responsive layouts, mobile-specific content, or device-dependent behavior such as CAPTCHAs or UI elements.

Available `?p_device` parameter values:

* `desktop` (default) – Emulates a standard desktop browser with a full-size viewport and desktop user-agent string.
* `mobile` – Simulates a smartphone experience with a smaller screen resolution, touch capabilities, and a mobile user-agent.
* `tablet` – Emulates a tablet device, ideal for scraping medium-sized layouts and hybrid mobile/tablet interfaces (available for Chrome only).

For example:

```
wss://username:password@ubc.oxylabs.io?p_device=mobile
```
