Samsung announced two new mid-range phones aimed towards the youth market, both with Super AMOLED displays. First up we have the Galaxy A5, which Samsung says is their slimmest phone ever at 6.7 mm. The A5 sports a 5" 720p Super AMOLED display, 13mp camera, 5mp front camera for selfie shots, 1.2Ghz CPU, 2GB of RAM, 16GB of storage memory and a 2,300 mAh battery. As in several of Samsung's latest smartphones, it uses a stylish metal body.

The second phone is the Galaxy A3, the A5's smaller sibling - with a 4.5" qHD (960x540) display. It looks pretty similar, but it's actually thicker at 6.9 mm. The specifications are a little below the A5: a 8mp camera (same 5mp front camera), 1,900 mAh battery, 1.2Ghz quadcore CPU, 1GB of RAM and 16GB of storage memory.

Both the A3 and the A5 will launch in China during November 2014, with other markets to follow.
