In the following video, Motley Fool tech and telecom analyst Andrew Tonner takes a closer look at the release of Samsung's much-ballyhooed new Galaxy S4 handset. Many analysts suggested the possibility before the unveiling that this could be the phone that puts an end to iPhone's dominance. But now that we've had a chance to see the phone itself, many are calling the upgrades "evolutionary" rather than revolutionary -- meaning it boasts incremental improvements in many of the phone's systems but no new features that really wow consumers. Andrew goes over the phone's enhancements and tells us why it will fly off the shelves but won't kill the iPhone.
