    This wasn’t very helpful…at all.
    In fact, at the end, I had the same exact screen as the last screen shot in your article. However, from there what? So what IS my Android version? Is Firmware the name of my Android version? There is no “Android version” written on the screen…
    Bear in mind that if somebody doesn’t know their Android’s version, its probably because he/she doesn’t know much about phones to begin with. So please don’t take for granted that we already know what’s what.
    Actually “Here our requirement was to find the Android operating system version and so you can find it at this point of time. ” was a pretty shitty ending sentence. It just left me hanging…frustrated.
