 appium:networkSpeed | Sets the desired network speed limit for the emulator. It is only applied if the emulator is not running before the test starts. See emulator [command line arguments](https://developer.android.com/studio/run/emulator-commandline) description for more details.
 appium:gpsEnabled | Sets whether to enable (`true`) or disable (`false`) GPS service in the Emulator. Unset by default, which means to not change the current value
 appium:isHeadless | If set to `true` then emulator starts in headless mode (e.g. no UI is shown). It is only applied if the emulator is not running before the test starts. `false` by default.
-appium:injectedImageProperties | Allows adjusting of injected image properties, like size, position or rotation. The image itself is expected to be injected by [mobile: injectEmulatorCameraImage](#mobile-injectemulatorcameraimage) extension. It is also mandatory to provide this capability if you are going to use the injection feature on a newly created/resetted emulator as it __enforces emulator restart__, so it could properly reload the modified image properties. The value itself is a map, where possible keys are `size`, `position` and `rotation`. All of them are optional. If any of values is not provided then the following defaults are used: `{size: {scaleX: 1, scaleY: 1}, position: {0, 0, -1.5}, rotation: {0, 0, 0}}`. The `size` value contains scale multipliers for X and Y axes. The `position` contains normalized coefficients for X/Y/Z axes, where `0` means it should be centered in the viewport. Values in the `rotation` are measured in degrees respectively for X, Y and Z axis. The capability is available since the driver version 3.6.0.
