Below is an instruction that describes a task. Write a response that appropriately completes the request.

### Instruction:

Create a detailed description for the following product: LG G2, belonging to category: Smartphone

### Response:
The LG G2 has a surprise in store with its innovative design concept. Instead of arranging the controls in the usual way on the side of the phone, they are on the back. This allows the user to get a firm grip while speaking on the phone or writing. Removing the buttons on the side has also allowed for a slimmer construction of the smartphone. This was further helped by a specially developed, step-like battery which promises long-term operation of the mobile device.
