I don't have much requirements about mobile phones. If it is a portable phone and can connect to the internet, that's enough for me. For me, I don't like big-screen phones, because it is hard to me to hold those phones by one hand. For example, I wanted to but a iPhone 7 Plus, but the experience of using this phone is not as good as I thought. Maybe my hands are a little small. I imagine that my future phone can control all my household appliances, which means I don't have to put the buttons on those appliances, and just using applications to remote control it.
I remember my first mobile phone was a slide phone of Samsung. I really enjoyed the feel when I slid my phone. I wonder that if this kind of phones could make a comeback in the future, and I would definitely buy it.
I think most of us are addicted to cell phones, and we all are the prisoners of phones that's why it's called cell phones.
