It is an essential requirement of any phone that you intend to purchase with the intention of using it for gaming that it has full 4G connectivity. The 800 MHz spectrum for 4G mobile communications in the UK is now available, six months ahead of schedule. This is of major importance to mobile phone users who use their phones for gaming. When playing at a mobile casino games on your phone good communications and connectivity is crucial, and this really does mean 4G. Although the current EE 4G 1800 MHz service is available le to around 60% of the population, this does not reach rural areas, while the 800 MHz spectrum can reach 98% of the population. The network providers are still playing catch-up, but full 4G should be available sometime in 2013.
Although there has been a lot of emphasis on processor speed and power, for instance the latest Samsung Galaxy 4 has a 1.9 GHz quad-core processor; this is not a major factor for mobile gaming. It is nice to have for other reasons, for instance console type online games but GamingClub.com/mobile-casino games need only moderate computing power; just about any Smartphone processor is adequate.
The dominating consideration is the display. A large and clear display is crucial when you are playing casino games; you need plenty of screen real estate for the buttons too. Here the latest generation of Android phones score highly. One of the largest displays is found on the Sony Xperia Z Ultra which has a 6.1 inch display, the previously mentioned Samsung Galaxy 4 has a 5 inch display, and the HTC One has a 4.7 inch display. Unfortunately the iPhone 5 display size of just 4 inches is a little on the small size, though it is rumored that the iPhone 6 will be larger.
The other consideration is the operating system. For instance the latest Nokia phones have a 4.7 inch display; however they use windows software which is not largely supported currently by mobile casinos.
