Having been all but left for dead, Finnish smartphone player Nokia (NYSE:NOK) deserves ample credit for engineering an impressive transformation over the last several years.

However, that might not be as easy for Nokia as one might think. In this video, Fool contributor Andrew Tonner gives his reasoning for why, despite its obvious improvements, Nokia could still find itself on the ropes again.
