Hey, I'm new here. My brother has Xiaomi Mi-1S (with S3 CPU dual core 1.7Ghz). Right now in these days the new Hongmi [WCDMA] became Avilable in online stores (with S400 quad core 1.6Ghz). My brother is a guy who like to play games on his mobile phone and he happy with his current phone. but my question is: Should I sell his phone for the new hongmi? and the new hongmi has good GPU to play games(more than the mi-1S)? I think it's a good deal because the hongmi 1S has better specs: - bigger and sharper display. - quad core against dual. - newer OS(4.3 while the mi-1s is 4.1) - more accecories. I know that the old hongmi is pretty laggy on heavy games while the mi-1s is almost not. What do you say? Thanks.
