    On my Galaxy Tab (GT-P1000, Android 2.3.3) using the default browser when I switch between tabs and then swipe to scroll down there is brief flash of the previously selected tab before the selected tab is displayed again and the scroll starts.

    Steps to reproduce :

    1) On a Galaxy Tab (GT-P1000, Android 2.3.3) open http://www.captainsjob.com/test/kendouimobile/examples/mobile/tabstrip/index.html 
    2) Select each tab in turn a few times
    3) Start a swipe down motion
    4) See the previously selected tab flash on screen then revert back to the tab you were on when you started the swipe

    KendoUI Mobile is going to be brilliant for me saving me lots of time and getting my product out of the door quicker than if I learned titanium/mono/sencha. I'm sure these Android issues will be ironed out I'm happy to do testing on my two android devices (HTC Wildfire S and the Galaxy Tab).

    Hi Gareth,

    We managed to reproduce this issue on the original Galaxy Tab with Android 2.3.3. seems the issue is somehow connected to the native Android scroller - for some reason it doesn't refresh its memory buffer contents before starting to scroll. We will investigate further if there's a way to fix this. As a workaround, you can try to disable the native scrolling in Android 2.x by preventing the default action on touchstart, like this:
    if (kendo.support.mobileOS.android && kendo.support.mobileOS.flatVersion < 300) {
        $(document).bind("touchstart", false);

    Let me know if this helps.

    All the best,
