Why Samsung would resort to such an under-handed move is still in question. The manufacturer has come out and said that it does not knowingly indulge in benchmark rigging. However, a lengthy analysis by Ars Technica has confirmed that the offending code that was causing devices to run on maximum frequencies has been removed from Samsung's official Android 4.4 KitKat build. After installing Android 4.4 KitKat, both the Galaxy S4 and Galaxy Note 3 function normally when a benchmark test is run.
Geekbench test results from Android 4.2.2 Jelly Bean to Android 4.4 KitKat do reveal a slight increase in scores, but nothing as drastic as the increase from Android 4.2.2 to Android 4.3. Ars talked to John Poole of Primate Labs, who mentioned that the increased score on KitKat is due to better tweaking by Samsung and not artificial inflation. “I’m inclined to think that the change between 4.2.2 and 4.4.2 is due to Samsung tweaking the overall power and performance settings rather than a new harder-to-detect boost.”
