stage.softKeyboardRect.height is not returning correct values (440px on galaxy s2, screenheight is 800px but height of softkeyboard less than half of the screen)

I get 440px on galaxy s2, by a screenheight of 800px -> but height of softkeyboard less than half of the screen. Seems it's a known issue and there are ane solving the problem... sometimes...

Isn't there a working solution ... is Adobe working on the problem?
