Features include 13MP rear camera, a 3000mAh battery and a choice of either 16GB or 32GB of memory storage.
LG Electronics has unveiled its latest smartphone that places all its buttons on the rear of the device.
LG, which is the third-largest smartphone maker in the world, said by placing buttons on the rear of the handset, users would keep a better grip on the device.
The back buttons can also be used to adjust its volume and activate its note-taking and camera apps.
The LG G2 runs using a 2.26GHz quad-core Qualcomm snapdragon 800 processor, designed to make it one of the fastest in the world.
The ‘KnockOn’ feature should allow users to turn on their phones by tapping the G2’s screen twice, rather than having to flip it over to access the power button.
Other features include 13MP rear camera, a 3000mAh battery that lasts a full day and a choice of either 16GB or 32GB of memory storage.
The South Korean company said users can also set up ‘Guest Mode’, which offers restricted access by displaying only pre-selected apps.
LG president and CEO, Jong-seok Park, said: "Our definition of innovation today is technology that truly resonates with consumers.
"We have always listened to and learned from consumers in pursuit of innovation. We took these insights to new heights in developing LG G2, the most exciting and ambitious mobile phone in our company’s history."
