What happens when I tap between the keys?
The touch generally activates the nearest key.

Sometimes the keyboard is not visible.
Tap in the text field to activate the keyboard.

Sometimes the keyboard seems to vibrate.
iPad’s “Multitasking Gestures” may react to an accidental four finger swipe,
it is possible to deactivate them in “Settings” “General”.

The adaptation seems to be too nervous.
