I am using a Samsung note 1. Thinking of learning how to Overclock it so it will be faster. I decided not to because there are alot of cons by doing it, like battery consumption, processor damage by over heating (if one is not exprience) ect... I decided never to try it.
Afternote:There is a trend to buy a slower android and than root it so it is like having a person using a note 2 = to buying a Samsung note 3.
