Its only been a week since Gionee debuted its super thin Elife S5.5 Android phone in China, but luckily for us, the company also brought it along to MWC. After playing with the 5.55mm-thick device for some time, we were left very impressed with its build quality. The aluminum frame was nicely machined and felt solid, whereas the Corning glass back panel added an extra premium feel, despite leaving fingerprints behind.
