Tomcsányi, Domonkos domi at tomcsanyi.netHi Anton, The ARM core of the Calypso platform is responsible for both the UI/apps and other tasks as well, there is no separate application processor as found in most of current phones. There are applications running on the phone presenting a UI as well as doing work on the ARM core for example the rssi application.
