I Bought a Korean version of note 3 , for a 70$
It works good so far after rooting it and using ramexpander !
I'm new on rooting and messing with android phones !
I was searching about effective ways to improve android phones performance !!
and i founded a lot of writings in the web !
that overclocking is effective and it improves the phone performance Significantly !
also a lot of people said that it's harmful and it would damage the phone permanently .
