Samsung is now expanding its line of Galaxy smartphones by introducing four new budget smartphones with Android KitKat OS. The four devices include, the Samsung Galaxy Core II, Galaxy Ace 4, Galaxy Young 2 and Galaxy Star 2. It has been reported by tech analysts that the sales of Samsung Galaxy S5 did not surpass that of iPhone 5S. The Galaxy S5 came with an expensive price tag and because of this reason many consumers did not purchase the flagship Galaxy S5. Still, it holds on to the title of the largest smartphone manufacturer in the world. In a bid to build up more customers by selling affordable devices, Samsung has announced the arrival of four feature-rich smartphones with affordable price tag. The new smartphones are expected to be powered with the most recent version of Android 4.4 KitKat which is also available on Galaxy S5. All the four new Galaxy phones are aimed at entry-level markets. As of now, Samsung has not announced the prices of these new smartphones. Experts feel that these handsets will be available for less than $150 so that it can rival with other affordable handsets from other brands.
