  • Hello Truc Luc,

    This is a by designed behavior, in windows runtime, after you click the home key, your application would go to the suspended state, and if it does not does not return from the suspending event within 5 seconds, windows assumes that the app has stopped responding and terminates it, so that its previous memory would be lost. The reason I think it is because as we know batteries often run low on laptops, tablets, and phones, because all of us tend to leave apps running even when we’re not using them. So it is acceptable to terminate app to save resource as memory and the batteries.

    Of course, for this scenario, there is a workaround to make your app be always alive, for details, please follow this blog: Managing app lifecycle so your apps feel "always alive".
