Wrong orientation handling on android ViewOutput

Following QML code works correctly on android excepting rotation handling. Honestly i don't understand how it rotates preview image, sometime it shows it rotated on 90%, sometime on 180%, i didn't find any logic there:

import QtQuick 2.0
import QtQuick.Window 2.0
import QtMultimedia 5.0

Rectangle {
id : cameraUI

width: 800
height: 480

color: "black"

Camera {
id: camera
captureMode: Camera.CaptureVideo
focus.focusMode: Camera.FocusAuto
focus.focusPointMode: Camera.FocusPointCenter
onCameraStateChanged: {
if(camera.cameraState == Camera.ActiveState)

{ camera.searchAndLock(); }
}
onLockStatusChanged: {
if(camera.lockStatus == Camera.Locked)
{ camera.searchAndLock(); }

}
}

VideoOutput {
id: viewfinder

anchors.fill: parent
fillMode: VideoOutput.PreserveAspectCrop
focus: visible

source: camera
Repeater {
model: camera.focus.focusZones

Rectangle {
border

{ width: 1 color: status == Camera.FocusAreaFocused ? "green" : "white" }

color: "transparent"

property variant mappedRect: viewfinder.mapNormalizedRectToItem(area);

x: mappedRect.x
y: mappedRect.y
width: mappedRect.width
height: mappedRect.height
}
}
}
}
