When four panels are opened, the device goes from smartwatch mode to smartphone mode with the appropriate change in UI. Icons are larger and bigger images can be viewed. In this mode, the remaining four panels remain stacked and stored. When the last four panels are unfolded and all eight are in use, the device shifts into tablet mode and requires both hands to operate. The seams on the displays are said to be minimal. The device will have at least one speaker and will work with an optional mouse and physical keyboard.
