# Device

The Device API exposes internal information about the device, such as the model and operating system version, along with user information such as unique ids.

This can help you

* Find out the operating system of the device - iOS, Android etc
* Find out app's version so you can send update or update alerts to user
* Find available disk , using which you can alert user to delete data etc
* Find uuid of the phone. This can be useful when you want to register the device on your server. E.g. Uber uses this ID to register the device on the app. So even if you change your sim card on the same device, you cannot create a new account.

### Example <a href="#example" id="example"></a>

```
import { Plugins } from '@capacitor/core';

const { Device } = Plugins;

const info = await Device.getInfo();
console.log(info);

// Example output:
{
  "diskFree": 12228108288,

  "appBuild": "123",

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://enappd.gitbook.io/capacitor-full-app-ionic-angular/features/pro-features/pro-addons/device.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
