Mobile phones are the wireless handheld devices that have allowed us to make calls and send texts for decades now, but with the evolution of the smartphone, you have the added benefit of an integrated computer running operating systems like Android and iOS. Both Apple's iPhone and Google's Android give you easy access to apps for both productivity and entertainment, plus games for play, cameras that can shoot great photos, and even built-in navigation systems. With the older 'feature' phones fast disappearing, the competitive smartphone market has taken over. Samsung and Apple are the leading manufacturers of the latest smartphones, followed closely by companies like Lenovo, LG, and Sony. Chinese manufacturers such as Huawei and Oppo have, in recent years, started becoming more popular, competing with the big boys on features while still offering up some great discounts and deals.
