Samsung Galaxy S4

The Samsung Galaxy S4 brings more innovation to a phone that's already at the top of its game. The design offers flexibility where others don't with access to the battery and the option to expand the memory via microSD.

Some may say that there's a feature too many and the design isn't as inspiring as some other devices like the HTC One, but if you opt for the Samsung Galaxy S4, you won't be disappointed. Samsung crams a large 5-inch Full HD display into a handset that isn't overly large, so despite going large, the size is still manageable.

Undoubted the Samsung Galaxy S4 will be the top smartphone choice for many, but recent launches bring more raw power. The Samsung Galaxy S4 will handle anything you throw at it, and beautifully so, but those looking for more power might be tempted by the LG G2.

QUICK VERDICT: We love it, honestly. The new design might look the same as the old, but it isn't. New, more squared-off sides mean it feels nicer than the old model, and it's got so many new features that it's impossible not to love some of them. Battery life is still a major issue for Samsung though, and that's a big deal for most users.
