Here all the review are almost negative. but I am using s7562 from last three year and I manage to get full performance from it. from Rooting, custom ROMs to Overclocking to CWM recovery to #XPOSED modules every thing that you ppl cnt imagine ive done it at all.
By this time I am comfortable with it with my experiments on it. I heard from every one that #Samsung phone Slow down after a couple of months. but its not the case with a #Superuser
