And now today, Samsung has went a step ahead by announcing Samsung Galaxy A9 - world's first smartphone with a whopping four rear cameras. This camera gives you the ability to manually control depth of field and focus on the subject. I spent a very brief amount of time with the Galaxy A9 at the launch in Kuala Lumpur, Malaysia and here are my initial thoughts. Unfortunately for tech enthusiasts, the A9 will not feature wireless charging. Reports out of Korea suggest the Galaxy X's screen would fold out into a 7.3-inch display.
All feature a 3D Glass curved back which makes them feel comfortable to hold in your hand.
Samsung will make the Galaxy A9 available in three colours; Caviar Black, Lemonade Blue and Bubblegum Pink. On the rear sits a fingerprint scanner, positioned neatly in the top centre of the phone's backside and away from the camera array. The A9 has a 3.5mm headphone jack and one speaker, while the S9 and S9+ ditch the headphone jack to offer AKG-tuned stereo speakers.
"When we deliver a foldable phone, it has to be really meaningful to our customer", said Koh.
The Galaxy A9 is the first product to spring from this plan, which could help fend off mid-range rivals like Huawei, Oppo, and Xiaomi, while boosting mobile revenues dragged down by sluggish Galaxy Note 9 sales. With the MicroSD card slot, the Galaxy A9 users can further expand up to 512GB.

Immediately after Kanye West revealed his bad iPhone passcode to the world, he said that Apple should build Trump the iPlane1. Kanye West and Donald Trump Jr . "It was something about when I put this hat on, it made me feel like Superman ", West said.
Of course, the main selling point of the Galaxy A9 is its innovative camera configuration.
Phones with dual camera arrangements are increasingly common, and even having three rear cameras is no longer uncharted territory- Samsung offers one in the Galaxy A7. This is to "soak in the light and create brighter images". Next, we have an 8MP 120-degree ultra-wide-angle lens that will provide more background in the shot that you are about to snap. More lenses doesn't automatically mean better experience though.
