I always believed that the screen is the most important feature of a decent smartphone, and that is why I really like to use large displays with at least 3.7″. The only Nokia to offer that so far is the Nokia E7 which has the magical 4″ (since 4.3″ is way too much). Nokia, however, did not only make it an AMOLED screen, but a CBD AMOLED display which reminds me of the SuperAMOLED display from Samsung. CBD stands for Clear Black Display, this technology is supposed to cancel the light that goes into the screen, making the reflections vanish and therefore offering a better image. Here are some shots comparing the AMOLED CBD screen on the C6 and the SAMOLED screen on the Galaxy S.
