Samsung appears to be working on another Galaxy A 8 smartphone, and it looks like it could be the slimmest handset the firm has ever released.

The mid-range Samsung Galaxy A8 weights 140g and measure in at just 157.7 x 76.7 x 5.9mm, Digital Spy reports citing reliable rumors blog Nowhereelse.

Leaked photographs of the device suggest that it will resemble a larger version of the Galaxy A7, with a 5.7-inch 1080 x 1920 Super AMOLED display on board.

Under the hood, the Galaxy A8 is said to pack an octa-core Snapdragon 615 processor, 2GB of RAM, 16GB of storage, and a 3050 mAh battery.

Its cameras reportedly clock in at 16 megapixels on the rear and 5 megapixels on the front, and a fingerprint scanner could also be included.

As Samsung is yet to officially announce the Galaxy A8, pricing and availability are uncertain.
