Android Kitkat has very confusing UI. Actually, Android UI has been like this so far.
There is a ‘turn around’ button on the bottom. it means “Go back”.
However, on top of the screen there is also ‘<‘ button. Usually there was so-called a hamburger button.
Both means “Go back”. However, there is difference where it goes back. The bottom one goes back to its immediate previous screen, while the top one goes way back to a list screen.
Probably from there different view controller was spawned ( if using iOS terminology )
Isn’t it confusing?
