There are so many contenders for 'Smartphone of the Year', so it may come down to a subjective choice. Arthur Goldstruck delivers his verdict...
Samsung Game Pad
Not confirmed for a UK release as of yet - but included for quirkiness; the S4 Game Pad teams up with your new smartphone for enhanced Android gameplay. Think Nvidia Project Shield on a smaller scale.
It boasts twin analogue joysticks, D-pad and four action buttons and doesn't look all that different to the Xbox 360 controller.
Key features: Adjustable for different screen sizes (so not S4 exclusive) .
Perfect for: Android game boys.
