### Amazon Fire OS Quirks
|
||||
|
||||
Amazon Fire OS uses intents to launch the camera activity on the device to capture
|
||||
images, and on phones with low memory, the Cordova activity may be killed. In this
|
||||
scenario, the image may not appear when the cordova activity is restored.

Android uses intents to launch the camera activity on the device to capture

### Browser Quirks

Camera plugin is currently implemented using [Web Activities](https://hacks.mozilla.org/2013/01/introducing-web-activities/).
|
||||
|
||||
### iOS Quirks
|
||||
|
||||
Including a JavaScript `alert()` in either of the callback functions
|
||||
can cause problems. Wrap the alert within a `setTimeout()` to allow
|
||||
the iOS image picker or popover to fully close before the alert
|
||||
displays:
