Latest reports indicated that the company wanted to give up on the home button since Android 4.0 (Ice Cream Sandwich), the operating system believed to power the handset, already integrated it.
According to South Korean newspaper Digital Daily, Samsung decided at the last minute that keeping the feature would be necessary.
In addition, the newspaper writes that the Samsung Galaxy S III will sport a 5 column user interface, similar to the Galaxy Note, and unlike the Galaxy Nexus.
Speculation is that Samsung wants to make the S III stand out from Android-powered devices, as well as the iPhone, which features a five-column icon layout.
Recent reports suggest that the Galaxy S III could be unveiled on May 22.
