Samsung Galaxy S4 to review

Now we finally have an S4 to review, just two simple questions remain. Most importantly, is this the best smartphone you can buy today? But also, has Samsung taken a big step forward over last year's S3 or is this more an evolution of that handset?
Given its big 4.99in display, the S4 is surprisingly svelte. It measures just 136.6x69.8x7.9mm and weighs only 130g. That makes it both smaller overall and lighter than both its immediate rivals, the Sony Xperia Z and our current favourite, the HTC One.The Samsung Galaxy S4 is among the best-looking plastic phones we've ever seen. It's a decent evolution from the S3, ironing out plenty of the minor flaws that its predecessor had. These include a USB port that didn't look very well cut out and a rear case that had quite a loose fit; with the S4, it feels that much more finished and as though more attention has been paid to the detail.
From the front the most obvious change is the thinner screen bezels, both down the edges and at other end. This puts the screen just 2.5mm away from the edge of the device and it's becoming hard to imagine this distance getting any smaller without seriously compromising the survivability of the handset when dropped. The sides have been squared off, compared to the S3, which makes it easier to grip though it looks a little chunkier for it. The areas above and below the screen are now far smaller, which has significantly reduced the amount of space for the physical home button and touch sensitive menu and back commands. This could have made them awkward, but the button needs an appreciably lighter press and we had no trouble hitting the touch sensitive controls.
