Apple is expected to launch two new iPad Pro models later this year, each with an iPhone X-inspired, redesigned design. While iPad pros are not supposed to have notch mounts, they should support Face ID authentication. which replaces the iconic main button. As a result, the iPad Pros 2018 will have slimmer bezels than their predecessors.
Significant reports from credible sources have uncovered these details about the incoming iPad Pro models in the past. But a brand new leak, which seems to confirm a previous rumor, suggests that even the new iOS tablets will pack a mysterious feature.
Posted on SlashLeaks These pictures show a protective cover for the new iPad that has a strange opening to the bottom of the tablet, on the other side where the home button would be placed.
If that sounds familiar to me, because 2018 iPad Pro CAD schematics that seeped out a few weeks ago, the same design Special feature showed.
As MacRumor's declares that the purpose of the opening is unclear. Earlier we had heard that the iPad Pro will have a Smart Connector that places the bottom panel so that users can dock the tablet in portrait orientation rather than landscape mode. These reports state that Face ID only works in portrait format on the tablet, which contradicts earlier rumors that Apple is upgrading Face ID to work in landscape mode. 
A backside fingerprint sensor, however, would make sense on a tablet, especially if the faceplate works only in portrait orientation. The Touch ID can be used when the tablet is anchored in landscape orientation. Before you ask, yes, the case has cutouts that indicate that docking the tablet in landscape orientation is supported.
Apple should introduce the new iPad Pros in September.
