Samsung has announced its new Galaxy A9 smartphone, which the company says is the first smartphone to include four rear cameras.

The Korean company's new Galaxy A9 device is aimed at the "Instagram generation", Samsung said on Thursday, and will go on sale in the UK in November, starting at £549.

The A9 has a 24-megapixel main camera, as well as telephoto, ultra wide-angle and depth lenses designed to help with a broad range of mobile photography.

The phone will sit beneath Samsung's flagship Galaxy S9 and Note 9 phones released earlier this year as the best of its mid-range devices.

Samsung, along with rival smartphone maker Apple, has come under increased pressure from lower-priced but premium-made handsets from the likes of OnePlus, Honor and other Chinese manufacturers including Xiaomi, forcing it to create a larger range of devices that house technologies normally reserved for flagship launches.

The new phone also comes with a fingerprint sensor on the back of the phone, mobile payment capabilities and expandable storage of up to 512GB - all features common on high-end smartphones.

The firm's president of mobile communications DJ Koh said the company was keen to offer the latest features to a wider range of people.
