One of the devices that I like to use the most is the smartphone. Smartphone has been common for humans all over the world. So, I have used it since I was in grade 6. It is a really convenient device.  It can be used to communicate, entertain, study, and many other activities. I often use it to chat with my friends, play games, or search for information on the Internet. It's also really small and easy to be taken away. One of the most conveniences is calling. With a few clicks, I can contact my friends even he is far away from me. For the following reasons, the mobile phone is my favourite electronic device.
