Samsung has just unveiled a new lineup of smartphones under its Galaxy A series.

The new handsets, which are mid-rangers, are Samsung's way of revitalizing its sales by offering consumers budget-friendly devices.

The latest smartphones introduced by Samsung to the public are the Galaxy A3, Galaxy A5, and Galaxy A7. All three models sport a metal uni-body design and glass display. Also, they run on the same Android 5.1 Lollipop operating system.

As various sources noted, despite being mid-range handsets, the three devices come with decent specs, Phandroid reported. The Galaxy A3, which is the smallest of the three handsets, packs a 4.7-inch Super AMOLED HD screen with a resolution of 1280x720 pixels. It's powered by a 1.5GHz quad core CPU and houses a 13-megapixel rear camera paired with a 5-megapixel front shooter. It comes with 1.5GB of RAM and 16GB of internal storage which can be expanded up to 128GB through a microSD card.

The Galaxy A5, on the other hand, comes with a 1.6GHz octa core chipset. It features a 5.2-inch FHD Super AMOLED display with 1920x1080p resolution. Like the Galaxy A3, the Galaxy A5 also features a 13-megapixel primary shooter and a 5-megapixel secondary camera. It packs 2GB of RAM and 16GB pf expandable internal storage. The device is powered by a 2,900mAh battery pack with Fast Charging features.

Last on the list is the Galaxy A7. Like the other two models, the Galaxy A7 also comes with a 13 and 5-megapixel camera configuration. As the largest model, it features a 5.5-inch FHD Super AMOLED display with a resolution of 1920x1080 pixels.

The device packs a 1.6GHz octa-core CPU and comes with 3GB of RAM and an expandable 16GB of storage. It runs on a 3,300mAh battery with Fast Charging.

All three devices come with support for Wi-Fi 802.11 b/g/n, Bluetooth 4.1, USB 2.0, ANT+ and NFC. In addition, the Galaxy A5 and Galaxy A7 feature the Samsung Pay mobile payment system.

The devices are expected to go on sale in China this month before heading to other markets next year. It is not yet clear if and when the three handsets from Samsung's Galaxy A series will reach the U.S.

As noted by CNET, Samsung may have decided to unveil a new line of mid-range handsets in order to win back the support of consumers. For the past few months, the South Korean tech firm has been struggling with the competition coming from the budget-friendly smartphones released by its Chinese competitors such as Xiaomi and Huawei.
