Tablet device with peek mode operation

A method performed by a tablet device having a display and a first sensor each coupled to a processor, comprising: when the tablet device is attached to a foldable cover comprising a plurality of independently foldable segments comprising a first segment at a first end of foldable cover having a magnetically attractable element and a second segment having a magnet that is detectable by the sensor at a second end of the foldable cover, the second end opposite the first end, wherein the plurality of independently foldable segments fold with respect to each other and the tablet device to form a folded state, altering an operating state of the display by the processor in accordance with the folded state, wherein in a tablet device support folded state the foldable cover forms a triangular structure by the magnetically attractable element in the first segment and the magnet in the second segment magnetically attracting each other when the first and second segments are folded one atop the other to form a first side of the triangular structure that is about equal in width to a second side of the triangular structure each of which is narrower than a third side of the triangular structure, and wherein in a first folded state where the first segment covers a corresponding portion of the display and the second segment is folded away from the display to reveal a corresponding first viewable portion of the display, the sensor detects the first folded state and sends a signal to the processor that causes the tablet device to present visual content only at the viewable portion of the display in a first peek mode.
