The Galaxy A9 joins the recently annoucned Galaxy A5 and Galaxy A7

Samsungs's Galaxy A9 Has A 6-Inch Display And A Huge Battery.

Though flagship smartphones have apparently stopped growing, most of them having 5 to 5.5-inch screens
, there's still a market for larger devices, and Samsung is hoping to grab some of it with its latest phablet, the Galaxy A9. 

Following in the footsteps of its predecessor, the 5.7-inch Galaxy A8, the A9 is a slim, elegant and large smartphone, with specs that are a hair or two weaker than those found in Samsung's Galaxy S line of devices. 
The Samsung Galaxy A9, which the company launched in China on Wednesday, does have several very important improvements.
Besides the 6-inch, 1080p AMOLED screen (which may not be an improvement for some), it also sports an enormous (but non-removable), 4,000mAh battery, which should hopefully extend the phone's battery life over the dreaded barely-one-day mark we so often see in smartphones these days.

Other specs include an octa-core Snapdragon 652 processor, 3GB of RAM, 32GB of storage (expandable via microSD cards up to 128GB in size), and a 13-megapixel camera on the back and an 8-megapixel selfie cam.
It runs Android 5.1.1 Lollipop — a trend we're seeing a lot these days, though Android 6 has been available since October. A fingerprint scanner and support for Samsung Pay are included as well.

All of these goodies are stuffed into a glass and metal case that's just 0.29 inches thin, and even though that's quite a bit fatter than the Galaxy A8's 0.23-inch thin profile, it's still pretty good for such a large phone. 
The phone will be available in China later this month; pricing and international availability have not been announced. 
The Galaxy A9 joins the recently annoucned Galaxy A5 and Galaxy A7 (not to be confused with older models of the same name — Samsung points out the difference by placing a "2016" denomination next to their names), which are already available in China.
The 5.2-inch and 5.5-inch phones both feature the same metal design and similar specs, but have much smaller batteries — 2,900mAh and 3,300mAh, respectively. International availability has not been announced, but the price in China is 2,398 yuan ($370) for the A5 and 2,699 yuan ($417) for the A7.
