New technologies will be used on mobile phone
Some new technologies are possible to used on mobile phones and they will change the mobiles greatly.
1, touch-free gesture control
It would be not necessary to touch the phone screen anymore, just need to make gestures to make remote control. Of course, there also need a screen for multiple applications.
2, Holographic projection
Holographic projection will help to zoom the display, then do you think full screen is necessary? You will have a portable projector.
3, Graphene battery
Graphene battery can be charging to full only minutes and safer than the lithium battery, although it is still in the lab, it can be expected to use massively very soon.
