Apple has instituted a new rule for Made for iPhone (MFi) licensing, requiring all cases to protect against drops of at least 1m (3.2 feet) over hard surfaces, sources say. That also includes any orientation, even in the direction of the display. Similarly, cases for all iOS devices must now offer a buffer of at least 1mm between the display and a flat surface when the device is upside-down. To achieve that, they can either cover the display glass completely or use a lip around the edge.
