The truth is amazing. The SD 600 is not a "mediocre" and well optimized SoC gives much war. So Far, the Max game Call of Duty and Magic 2014 smoothly ... both titles are not compatible for Note 3 (and this rides a .. 800 SD) which can not be the reason but there is.
The sense is very well optimized and lagea not at all, not with chorromil apps open (and that 2 gb of ram max are DDR2 and DDR3 not like the Note3).
As stated Pirelli's slogan: Power without control is useless ...
To see how it would feel to Max kitkat.
