Unsolved SwipeViews works in simulator but not on a device

[a.burks]

I have implemented a simple swipe view for an Android app, that almost follows the template for Android apps:

SwipeView {
    id: swipeView
    anchors.fill: parent
    currentIndex: 1

    Item {
        id: firstPage
        Loader {
            ...
        }
    }
    Item {
        id: secondPage
        Loader {
            ...
        }
    }
    Item {
        id: thirdPage
        Loader {
           ...
        }
    }
}

I can easily swipe to the left page in the simulatr. Unfortunately it's not possible on the device. Has someone an idea?
