The HTC One was unveiled in February and, along with the Samsung Galaxy S4, is the top Android handset on the market featuring a number of custom camera and software innovations that make it entirely unique and original.
Meanwhile the iPhone 5 is Apple's current flagship smartphone, at least until the rumoured iPhone 5S hits the shelves. Released late last year, despite being late in its product life cycle, the device is still viewed as the benchmark by which many people judge and compare any new smartphone.
No doubt Apple has some impressive tricks up its sleeve for the next iteration, but for now it remains a top contender that Samsung, and HTC, will be measured against.
As such, our head to head review between the HTC One and iPhone help show not only what Samsung's S4 will have to compete with but also how these heavyweights square off against one another.
