There were speculations that the smartphone will be exclusively available in China. However, recent leaks indicate that the Nokia 6 will make an appearance at the upcoming Mobile World Congress in Spain.

HMD Global has the rights to sell the Nokia 6, and it is available for $250. The reservations for the unit in China costs CNY 66 ($9). This guarantees that a customer will be among the first to get the device.

The Nokia 6 device has got many tech enthusiasts excited as it will have features on par with high-end devices from Apple and Samsung, but it will have a lower price. The device is likely to come with a dual SIM and support for LTE network capabilities.

The Nokia 6 will sport a 5.5-inch LED screen protected with a Corning Gorilla Glass 3. The device will come with Qualcomm's Snapdragon 430 and an Octa-core 1.4 GHz Cortex-A53 with Adreno 505 GPU. It will have 64GB of internal memory capacity and 4GB of RAM. The device will come with a memory card slot.

The Nokia 6 will have a 16 megapixels dual tone flash with f/2.0 and phase detection autofocus. The front camera will be 8 megapixels with f/2.0, running at 1080p for video calls. It will also have a fingerprint scanner and a 3000 mAh battery.
