Smartphones are indeed a great technological advancement that brings so much convenience to humans. But we surely cannot neglect the downside of them and its certainly worth the attention. It's not uncommon to see children these days playing with the cell phone even if they're just kindergarten kids. This is very much worrying as the overreliance on phone not only brings about health concerns but also social problems like parents not interacting with children as well as the days when cell phones were just a device for calling. I'm not even sure if it's really good for cell phones to have evolved into what they now are.
