A month ago I bought a new smartphone. I had wanted to buy it for a long time because my old phone had small memory capacity and a cracked screen.
When I came home from the shop, I spent about an hour exploring features of my new phone. It was easy to do it because of the phone intuitive control buttons.
I think smartphones are cool gadgets that make our lives so much simpler and more interesting. Now I use my phone very often - probably a few hours a day.
