Samsung Electronics today announced the latest Galaxy A series, including the 5.7-inch A7, 5.2-inch A5 and 4.7-inch A3 smartphones, with refinements in design and performance.

The Galaxy A features a metal frame and 3D glass back. The series is available in four colors including Black Sky, Gold Sand, Blue Mist and Peach Cloud.

Samsung has upgraded the front cameras of the new smartphones. Both the a7 and A5 models feature front and rear 16-megapixel cameras, which are now more stable with accurate autofocus. The A3 model has a 13MP rear and an 8MP front shooter.

User scan touch anywhere on the screen to easily snap a high-resolution selfie with the floating camera button and use the display as a front flash. The camera on the Galaxy A offers a simplified UX, including easy swipe to quickly change modes or instant filters to activate picture effects. Users can leverage modes such as the Food Mode, to optimize photos and enhance the color of images.

For the first time on the Galaxy A series, the smartphone offers IP68 water and dust resistance.

The Galaxy A also provides a larger memory, as well as expandable storage with microSD support up to 256GB. With a longer battery life and Fast Charge, the device powers up in no time. The Galaxy A is equipped with reversible USB Type-C port for easy connectivity including hassle-free charging. It also features Always on Display so users can quickly glance at the time and calendar without waking up the device, saving time and battery.

With Samsung Pay, users can make mobile payments almost anywhere through Magnetic Secure Transmission (MST) and Near Field Communication (NFC) technology, and back up data and images through Samsung Cloud.

The Galaxy A will be available in Russia in early-January and will be expanded to global markets.
