a minor logical fault:
When auto-rotation is active, in landscape mode, selecting either full or mini qwerty both gives full qwerty.
In portrait mode, selection works.
(I'm using N97mini 12.0.110)
This is a bit confusing. I suggest simply removing the non-selectable "mini qwerty" from the menu when in landscape mode, and auto-rotation is active. Or to make a manually chosen selection override the automatically chosen layout.
