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

The smartphone will go on sale in the UK in November, starting at £549 (around $724).

It has a 24-megapixel main camera, as well as a 10-megapixel telephoto with up to 2x optical zoom, an 8-megapixel ultra wide-angle lens with a 120-degree field of view (and slight fisheye effect) and a 5-megapixel camera with emphasis on creating excellent depth of field. It also sports a 24-megapixel selfie camera.

The company added that the new smartphone supports the Intelligent Camera system as in the flagship Galaxy Note 9, which automatically identifies objects to provide users with optimized shooting modes.

The Galaxy A9 also notifies users when photos are out of focus or when it detects a person has blinked their eyes. Such features can allow shooters to get better results. It is also capable of gathering more light in dark environments, enabling users to get more vivid photos.

The Galaxy A9's cameras beat LG Electronics's V40 smartphone just showcased earlier this month, which has three rear-facing cameras.

The Galaxy A9 comes with a 6.3-inch display with an aspect ratio of 18.5:9. The battery capacity stands at a solid 3,800mAh. It is powered by an octa-core Snapdragon 660 processor.

The smartphone will be released in two editions -- 6GB and 8GB RAM -- with internal storage capacity of 128GB, which can be extended by 512GB using micro SD.

The phone also comes with a fingerprint sensor and mobile payment capabilities.

Along with the black model, Samsung also adopted gradient colors for the blue and pink editions of the Galaxy A9.

The A9 joins Samsung's existing line-up of mid-range phones, one that includes the A7 - a device that features three rear cameras - which was unveiled last month.
