Microsoft’s Nokia has announced three new Lumia smartphones at the IFA trade show in Berlin today, the Lumia 730 Dual SIM, the Lumia 735, and the Lumia 830.

The new models compliment the recently released Nokia Lumia 530 and the Lumia 630.

The Lumia 830, featuring a 10MP camera, is Nokia’s attack on Samsung and Apple, priced competitively at about £300.

Expected to reach the market this month, the phone will run on Windows Phone 8.1 with the Lumia Denim update. It’s got a 5-inch Gorilla Glass screen and a 1.2GHz quad-core Qualcomm Snapdragon processor.

There’s 16GB of in-built memory, and obviously the token 15GB of Microsoft OneDrive storage.

Weighing just 150g, Nokia said that the smartphone’s performance is just as good if not better than Samsung’s flagship equivalent.

Nokia said: "Launched today, and oozing high-end style and performance, we welcome the thinnest and lightest family member to land all of our flagship innovation and experiences, the Lumia 830.

"Continuing the Lumia design legacy, the stylish Lumia 830 will be available in bright orange, bright green, white and black. At just 8.5mm thin, it’s our thinnest and lightest Lumia to date, with metal and polycarbonate that screams premium design, durability and performance."
