    Math.random() issue on e71

    I'm currently writing an app for my e71 which requires the Math.random function. However, I have found that each time I start up the app on the e71 it will produce the same sequence of random numbers. I have tried seeding it with Date().getTime() and Date().getSeconds(), and although it produces a different set of numbers, the sequence of numbers is still the same on startup.

    Has anyone had this issue before, and does anyone know how to resolve it?

    Welcom to Forum Nokia dibo!

    Could you check the firmware version of the E71 (*#0000#)?

    I was able to reproduce the issue with N96 as well.
    Unfortunately the only workaround I can think of is implementing a custom pseudorandom function.

    Google returns a couple of Mersenne-Twister implementations in JS. Those could be worth of trying.

    Not a solution, but a possible workaround: you could try by multiplying the random generated number for the current Date milliseconds. This way the obtained numbers should be different each time the widget is executed.
