The Split Keyboard has never been available for any iPad model with a screen greater than 10.5”. As such, Split Keyboard is only available for these models of iPad:
- iPad mini (5th generation and later)
- iPad (5th generation to 9th generation)
- iPad Air (3rd generation)
- iPad Pro 9.7-inch
- iPad Pro 10.5-inch
The iPad User Guide, an often overlooked source of information, details availability of this feature:

Dynamic volume controls were introduced with release of iPadOS 15.4 onwards. The “logic” behind dynamic volume controls is such that regardless of the screen orientation, the relative function remains constant - as follows:
- When the physical buttons are positioned on a vertical edge of the iPad, the uppermost button will always increase the volume. Conversely, lower button will decrease the volume.
- When the physical buttons are positioned on a horizontal edge of then iPad, the button on the right will increase the volume - while the button on the left will decrease the volume.
When the “penny drops”, the feature makes sense.
For reasons known only to Apple, the ability to disable this feature is not available for any new models of iPad and iPad Pro that have since been launched - these models being:
- iPad Air5
- iPad mini6
- fourth generation iPad Pro 11”
- sixth generation iPad Pro 12.9”
- iPad10
This is documented within this recently updated Apple Support document:
