A user device includes a display screen and one or more processors. The one or more processors are configured to preload one or more user applications in a background mode, in which User Interface (UI) displays associated with preloaded user applications are invisible on the display screen, to detect a launch of a UI display that is associated with a given preloaded user application, to assess whether the UI display is a preload-initiated UI display that is invoked due to preloading of the given user application, or whether the UI display is a user-initiated UI display that is invoked due to an action by the user, to handle the UI display using a first handling scheme if the UI display is assessed to be a preload-initiated UI display, and, if the UI display is assessed to be a user-initiated UI display, to handle the UI display using a second handling scheme, different from the first handling scheme.
