Methods, apparatuses, and systems for updating a User Interface (UI) in a Remote UI (RUI) client are described. Upon detecting a change in its capability, the RUI client stores a UI state of a UI page and requests a RUI server to update the UI page according to the changed capability. The RUI client receives a UI page updated according to the changed capability from the RUI server, where the stored UI state is reflected in the updated UI page, and the RUI client renders the UI state-reflected updated UI page.
