From soft “bodies” to self-repairing screens, from solar charging to the use of more advanced materials, some ideas about future mobile phones sound more like something from a science fiction movie.

Using sustainable materials and resources to manufacture mobile phones is one of the future trends. A study found that extending the life of smartphones by just one year could save the carbon emissions of 2 million cars per year.
