You're missing the point. IT'S NOT THE OS!!! There was no sensor at such size with 41 MP during the time. Also, there was no SoC powerful enough to process such images. Even, the current (thought to be) most powerful SoC, Exynos, even Tegra 3, can't cope with 41MP. 808 may suffer CPU wise, however, GPU and DSP wise, it's in a league of its own.
