from community,
1.using the provided code create an iPad or iPhone app
2.starting in landscape mode, slowly rotate

results:before the app UI changes over to portrait, the screen changes to white, meaning the orientation change handler fired prior to the actual event.

var mainWin = Ti.UI.createWindow({//url:"main.js",

                              tabBarHidden: true

var decksTab = Ti.UI.createTab({title: "Decks", window: mainWin});
var tabGroup = Titanium.UI.createTabGroup({});
mainWin.tab = decksTab;
mainWin.tabGroup = tabGroup;

mainWin.orientationModes = [




'orientationchange', function(e) {
    if (e.orientation == Titanium.UI.LANDSCAPE_LEFT ||
        e.orientation == Titanium.UI.LANDSCAPE_RIGHT) {
        mainWin.backgroundColor = "#fff";
    } else {
        mainWin.backgroundColor = "#000";

    Any chance of this getting into 1.6? On the main screen of my app I had a background image behind a tableview. If I take no action, the image gets squished to fit into landscape mode, so I had to create a separate image for landscape, and set that image when the orientation event fires. But because of this bug, when the user is holding the device at certain angles the image rapidly flips back and forth between portrait and landscape versions, despite the screen not rotating, and it looks pretty unprofessional (and many users don't connect it with an orientation problem). For the latest release of my app I had to replace the background image with a plain colour to avoid this problem, but now I have users asking me why I took away the image, and asking for it back.

    I've noticed it while developing my new app. Extremely annoying, and makes it unusable, since the rotation logic is expensive, and because of this bug, it is fired multiple times even though the devices isn't rotated. I ran the issues testcase compiled with Ti 1.7.3 on an iPad running iOS 5, and the issue is still there. Please fix!

    Bug is still valid, occurs in: TiMOB sdk version: 1.7.4, 1.8.0.v20111028154620 Studio version: OS version: Mac OS X Lion Devices tested on: ipad 4.3.5, iphone 5.0 Note: Bug is more prominent if the device is in landscape orientation and you tilt (pitch axis) the device back and forth.

    Issue seems to be reproducible using an iPhone 3GS with TiSDK 2.2.0v20120814103312.

    Ti.Gesture.orientationchange is an event triggered by the hardware accelerometer, and does not reflect the window's orientation. Watch TIMOB-10790 for the new event to listen for.
