    Hi,

    I'm doing a little game with Qt on Android. Everything was fine but when I got my new Phone (Nexus 4) I noticed that my Inputs were not recognized correctly.
    After fiddling around some time I realized what the Problem was: The MultiPointTouchArea does not receive updates on its touchPoints when I move my finger VERY slow over the screen. Is this a known Problem? Is there a workaround? Can I somehow fix it?!

    • I could not reproduce the Problem on my old Device (Sony Xperia U)

    • its not the phone, slow movements are recognized perfectly on the home screen, and with the developer option to show touches i see that everything is updated as expected

    • tried all kinds of android sdk-levels

    • tried 5.2 tody... it is not fixed (new Problems though :-o)

      Hi and welcome to devnet,

      For known problems, you can check the "bug report system":http://bugreports.qt-project.org

      If you have found new problems, you could consider creating new reports, a minimal compilable example is a great plus to help debugging things.

      You can also use the interest mailing list, you'll find Qt's developers/maintainers there (this forum is more user oriented)

        Hey, thanks for the reply.

        funny enough the same bug was apparently reported two days ago there... If anyone else is facing this problem, here is the direct link: "QTBUG-33729":https://bugreports.qt-project.org/browse/QTBUG-33729
