### Instruction:

Create a detailed description for the following product: Nokia Lumia 820, belonging to category: Smartphone

### Response:
The components in the interior of the 820 are arranged so that they provide good performance and at the same time a slim, compact design of the housing. Combined with its rounded edges, this means the smartphone lies very well in the hand and can easily be operated with one hand. The shell can be removed and replaced with a wireless charging attachment or with various shells in bright colours.
