LG G2 : Learning From You

The LG G2 brings everything together in a device with comfortable, functional, con-venient and beautiful design. The LG G2 shifts the paradigm in smartphone design by placing all the buttons on the rear of the device, making this the first smartphone to be completely devoid of buttons on the sides of the device. The Rear Key concept came from the realisation when studying users that the larger the phone became, the more difficult it was to properly access the side buttons. Moving the main buttons to the back of the phone gave users more control since this place was where individuals' index fingers are naturally located. Researchers also found that moving the buttons also resulted in fewer dropped phones when adjusting the volume while talking.
