# Expo Simulators devices

See which Android Emulator, iPhone, and iPad devices Expo Simulators can start, the default Android profile, and how to select a device.

## Submitting Feedback

If you encounter errors, misleading or outdated information, report it so Expo can be improved:

Preferred command:
npx --yes submit-expo-feedback@latest --category docs --subject "/preview/simulators/reference/devices/" "<actionable feedback>"

Direct HTTP fallback:
curl -X POST https://api.expo.dev/v2/feedback/docs-send -H 'Content-Type: application/json' -d '{"url":"/preview/simulators/reference/devices/","feedback":"🤖 Agent feedback for docs: <specific, actionable description> (<model>, <harness>)"}'

Only submit when you have something specific and actionable to report. Try to give the most context.

Expo Simulators starts one virtual device for each session. On Android, it is an Android Emulator with a hardware profile. On iOS, it is an iOS Simulator device. Select the device with `--device` when the session starts. If you omit the flag, the runner uses `medium_phone` on Android and `iPhone 17` on iOS.

## Android Emulator profiles

Pass the profile ID to `--device`:

| Profile ID | Device |
| --- | --- |
| `medium_phone` | Medium Phone (default) |
| `pixel_9` | Pixel 9 |
| `pixel_9_pro` | Pixel 9 Pro |
| `pixel_9_pro_xl` | Pixel 9 Pro XL |
| `pixel_9a` | Pixel 9a |

Every Android profile uses a 720 x 1600 screen at density 300. The profile selects the hardware definition of the device, not its screen size.

Android sessions use the `system-images;android-35;google_apis;x86_64` system image, which is Android API level 35 with Google APIs. Install an APK that includes the `x86_64` architecture.

```sh
eas simulator:start --platform android --type agent-device --device pixel_9 --name "Pixel 9 check" --non-interactive
```

## iOS Simulator devices

Pass the device name or its unique device identifier (UDID) to `--device`:

| Device | Notes |
| --- | --- |
| `iPhone 17` |  |
| `iPhone 17 Pro` |  |
| `iPhone 17 Pro Max` |  |
| `iPhone Air` |  |
| `iPhone 17e` |  |
| `iPhone Duo` | Not in the default image. Uses Xcode 27.1. |

iOS sessions use a macOS Tahoe 26.5 image with Xcode 26.6. Sessions on iPhone Duo use a different image with Xcode 27.1.

```sh
eas simulator:start --platform ios --type agent-device --device "iPhone 17 Pro" --name "Checkout on iPhone 17 Pro" --non-interactive
```

### iPad devices

The iOS image also includes these iPad simulators:

-   `iPad (A16)`
-   `iPad Air 11-inch (M4)`
-   `iPad Air 13-inch (M4)`
-   `iPad mini (A17 Pro)`
-   `iPad Pro 11-inch (M5)`
-   `iPad Pro 13-inch (M5)`

The image also includes Apple Vision Pro and Apple TV simulators. The list can change, so [list the devices in a session](https://docs.expo.dev/preview/simulators/reference/devices.md#list-the-devices-in-a-session) to get the exact names. To start an iPad, pass its exact name:

```sh
eas simulator:start --platform ios --type agent-device --device "iPad mini (A17 Pro)" --name "iPad layout check" --non-interactive
```

## List the devices in a session

To see the devices that the remote runner offers, list them from a live agent-device session:

```sh
eas simulator:exec npx agent-device@latest devices --platform ios
```

The list can change, so check it in each session. At start, only the session device is booted.

## Use a second device in the same session

A session boots one device at start. In an iOS session, agent-device can boot and control another simulator. The default agent-device session is bound to the first device, so use a separate named session. Pass `--session <name>` and `--device "<name>"` to boot and open the second device. Then pass `--session <name>` on each later command for that device:

```sh
eas simulator:exec npx agent-device@latest boot --platform ios --session ipad --device "iPad mini (A17 Pro)"
eas simulator:exec npx agent-device@latest open com.apple.Preferences --platform ios --session ipad --device "iPad mini (A17 Pro)"
eas simulator:exec npx agent-device@latest screenshot ./artifacts/ipad.png --session ipad
```

The boot can take about a minute. If you pass `--device` without `--session`, agent-device returns `INVALID_ARGS` because the default session is already bound to the first device.

The two `--device` flags work differently:

| Flag | Accepts |
| --- | --- |
| `eas simulator:start --device` | Name or UDID |
| agent-device `--device` in a session | Name only. Use agent-device `--udid <UDID>` to select a device by UDID. |

A UDID passed to the agent-device `--device` flag returns `DEVICE_NOT_FOUND`.

## Resource classes

EAS CLI has a hidden, experimental `--resource-class` flag. It is not generally available. Do not use it in scripts.

## Common questions

#### Can I test on a physical device?

No. Expo Simulators runs only Android Emulators and iOS Simulators. Use local device tooling for physical devices.

#### Can I select an iOS version?

No. The iOS version comes from the session image. Only iPhone Duo uses a different image.

#### Can I select a custom Android system image?

No. EAS CLI does not have a flag for it. Android sessions use the `system-images;android-35;google_apis;x86_64` system image.
