If you’re a just another smartphone user and don’t know much about Android updates, fret not, you’re not missing out much; although the update does come with some pretty neat new features for the geeky ones.
All you need to know is that Google is making Android smoother and faster in Android 4.3 Jelly Bean. Whether there’s a need to upgrade, it all depends on your devices. If you’re not sure about it, just let it be and stick to your current Android OS. Chances are, you’ll be having a new smartphone by mid next year.
