Samsung is in the lead among manufacturers of Android-based phones, and it looks like everyone loves those shiny touchscreens!

None of this is stuff that we had not heard before, but it is interesting that Apple continues to hold sway over the rest of the industry players despite Samsung and the rest of the contenders nipping at its heels. It’s also fascinating to see the continued rise of smartphones, a trend that clearly indicates that they will soon replace feature phones for the majority of consumers in the market.
