I don't think I've that features yet on global rom.....i tried to long press like I did on my iPhone and it makes nothing....I think have to wait for the update, unless using china set/rom

sorry for the wrong info....I tried again and works now, but I only managed to do that on people's image only at the moment, not like iPhone... waiting for the global update for a better outcome and so on, since the china version already release the update, i think i might get it sooner or later
