The smallest (4-inch WVGA), and apparently the most low-end model under Polaroid's unlocked Link series, the Link A4 comes with quite a modest 4GB-512MB memory-RAM duo. Just like its A5 and A6 siblings, it runs on a 1.3GHz dual-core processor, but comes with a rather weak pair of sensors at 2 (back) and 0.3 megapixel (front) respectively. Its network reach is limited to HSPA+ networks, which is not quite on par with LTE speeds, but potentially comes with a wider coverage by using 3G networks. Wrapping up its specs is a 1400mAh and Bluetooth v3.0.
Also known as Polaroid A4, Polaroid A4BK.
