As a man once said: “Fool me once, shame on — shame on you. Fool me — you can’t get fooled again.” How true that saying is regarding the promises of high-definition mobile screens. Samsung fooled me once with the Galaxy S series, the Pentile-based display of which gave me headaches just to look at. And now, after they fix that problem with the Galaxy S II, I hear they’ve brought it backfor the Galaxy Nexus? Can’t get fooled again, Samsung. Can’t get fooled again.
