Gionee Elife S5.5 is currently the thinnest smartphone out there, but somehow Gionee managed to put a 13MP shooter on the back of the 5.5inch device although the 13MP module protrudes out considerably. The Gionee Eife S5.5 is powered by a MediaTek Octa-core processor and has a 5inch Super AMOLED display making it a higher mid range smartphone.
