I always end up pulling a late one when a new rom comes out
Don't Know if this will help & I know it's a pain in the ass re-flashing your rom ( so if anyone has a better solution, I'd try that first )
But the Gallery from Note ll would ( in my humble opinion ) always be first choice & I had no probs setting a black lock screen.
Hope this help chief!
yer ill giv it a try cause my fone take two seconds to set back up but i really like the gallery i choose as u can zooom into pics and scroll left and right through to next (couldnt before had to exit from zoom then swipe across)
worth a shot though are you using noteII one? whats that one like??
