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. The first sensor is an ultra wide sensor with 120-degree field of view, f/2.4 aperture, and 8-megapixel resolution. Below it is a 10MP telephoto lens with 2X optical zoom that sits above the 24MP main camera.
Samsung describes the Galaxy A9 as the world's first "quad-camera" phone. Powering up the phone is, surprisingly, a Qualcomm Snapdragon 660 SoC clocked at 2.2GHz, 6GB RAM, and pretty sizeable 3800mAh battery.
It will remain to be seen as to whether the Galaxy A9 Star Pro will be making its way to our shores but we will be reaching out to Samsung Australia after the launch for local availability and pricing. Samsung has gone all-out in the memory department because the highest specifications version of the newly announced smartphone features up to 8GB RAM and 128GB of internal memory, though this variant is going to be limited to certain markets. It isn't clear how these cameras work seamlessly together, I'd assume the camera UI switches between lenses at various zoom levels, and all make use of the depth sensor for effects. Samsung is offering you a lot more ways to capture photos that one may otherwise be unable to do with regular dual cameras.
There's a rear fingerprint scanner too, plus a headphone jack and USB-C port on the base of the A9.

Sitting at the top is an 8-megapixel ultra wide-angle sensor with f/2.4 aperture and 120-degree field of view. Samsung is set to put all the rumors to rest when it launches the Galaxy A9 (2018 ) later today.

How much those four cameras are worth it to you will likely come down in price.
Ru Bhikha, mobiles expert at uSwitch.com, said Samsung's decision to launch the A9 may be a response to the upcoming release of the year's third iPhone - the XR - and lower-than-expected sales of its S9 earlier this year.
