So what's your point for posting these stuffs here?I don't see how processor is really related to those swiping and all that,but what I can say is when I compare my Nexus 4 to my cousin 4s in subway surfer,the smoothness on nexus 4 is much more noticeable,I also tried games like temple run,temple run oz,and some other game,so in the end for us(maybe only me),the price of the 4s is expensive than nexus 4 and yet the nexus 4 has a better smoothness,EVEN if nexus 5 is slower or laggier than iPhone 5s,in the end,its still cheaper

Then perhaps we should remove the swipe to left to camera, if a simple button is a better solution.
I mean it's not a big deal, but since android has reached a stage where they are polishing every aspects, these are the details they could look at.
I am a software developer myself, having two similar features at the same place seems like unnecessary and not very elegant.

But well now i look back from the froyo android to now, android has some really amazing journey!
