Honeycomb, the first Android version designed specifically with tablets in mind, was released way back in February 2011. It was built exclusively for large screens and was never meant to reach phones, but it paved the way for Ice Cream Sandwich, arguably one of the most significant updates to ever hit Android. Taking several cues from Honeycomb, Android 4.0 brought about some of the biggest changes to the OS, not the least of which was the advent of virtual or on-screen navigation buttons.

At the time, the use of virtual buttons on phones polarized opinions: some hated the idea while others were quick to sing its praises.
