Xamarin Timer is not Running as long as it says

I have developed the background service and use the Device.StartTimer to call my service. Its work fine on Emulator but the timer delay is not working properly on device. Please guide what is the problem in my timer code. Its not giving the 2min delay.


                MessagingCenter.Send<string>("OK", "counterValue");
                //count += 1;
                return isRunningTimer;

    Its work fine on Emulator but the timer delay is not working properly on device.

    Are you saying that your timer delays work well on emulators, but not on real devices?

    Besides, when we use a Timer, we should know that when we return true, the Timer repeats again, and vice versa.

    So, you can recheck the value of your variable isRunningTimer.

    Device.StartTimer(TimeSpan.FromSeconds(30), () =>
        // Do something
        return true; // True = Repeat again, False = Stop the timer
