i got korean g2 model 320L i geuss.... Its working great. My bhanja is a guru type . He was with me and he did antutu benchmark. Hardware test , battery test , screen test , 3g test, camera test before buying. The shop keeper gave us choice of international g2 rom or g3 rom. We opt for g3 rom. And it is working great till now.
But i must say there is always a risk in buying abroad set . Specailly frequency problem. Korean set frequecy may not match pakistani operator frequencies. So before buying do antutu bench mark . It will tell you the exact model no. Of cell . Put this model no. On internet and check its 2g , 3g , 4g bands . This is what i did before buying g2. And i found that this particular cell 4g frequency do not match pakistani operators 4g frequency. So 4g will never ever work on this cell in pakistan in any case. But yes 3g frequency match and 3g is working like a charm.
And this is not the only thing to check you have to check charger battery , back cover also that are orignal ang working . Cause now cells have a lot of sensors in their back cover too.
So my experience is good. And i am going for a korean optimus g ar may be g pro soon.
You can always pm me to get my cell no. In case you have any other question
1 more thing try to avoid samsung if going for korean cell instead go for Lg. cause samsung have lot of fake or replicas.... And Lg dont
