side only? i prefer if it covers the whole back. full casing
type *#0*# in the keypad. do all the test

Dont forget to ask them if anything happened between (time limit) can change one on one or not.

It happened to me,test the phone with *#0#*,everything is great when at shop,but after one hour,the hp hang,need to open battery and restart,after that screen not showing anything,lucky the blue cube still got stock and i demand one on one exchanged ,i stress out i dont want to claim warranty,i just use it for an hour,and not even single msg or call has been made out yet.

my sgs3 is from celcom blue cube,yes make sure of it,after the replacement,i hang out at the cube for 1 hour just for the testing
