This Has Been Tested on the SIII Mini So it's Applicable on the S Advance the same way like the Quad Lockscreen was applicable on SIII Mini and i got it done on the S Advance....
Dev's Can try it out and all themer's can also try... do ur backups, nandroids and then start ur work safely.... If you can do it successfully then lemme know and report back on the thread so that the people around the thread can also do it
