view story

http://forum.xda-developers.com – I just recently flashed my GS3 with a stock rom, everything went well but when i tried to customize my apps on my home screen. All the apps moved except the 4 at the bottom, they are just locked there, i press and hold down on them.. nothing. is there some way i can move them or is it permanently stuck? :confused: I have had this phone for about 6 months now and i know how to use it , i have cm10 on it before i stocked it.
