This app. just magically appeared yesterday, days after my 4.3 update and I inadvertently selected the simpler screen which unwantedly threw me from Oz back to Kansas. It took me (a non-technie, non-Geek form) into a tizzy...I mean wtf? Why is this app necessary and why did it creep into my Android life? Besides adding another step to return to the home screen, what's the benefit?
