The biggest flaws actually lies in its biggest strength...the display. Amoled is subjectively but arguably better than LCD at this stage. Either way the screen is not "true" 2k as the specs show. With that aside the biggest flaw is the "deceptiveness" of the screen being 5.7 inches. When the "black bar" shades the top edge to keep the 16:9 viewing ratio for movies, games etc. the amount of "true screen" goes down to the 5.4/5.5 inch range.
