Hello guys, ive had the same problem with the ghost clicking and flickers after the screen replace because of cracked glass. Id read all the above and tried pretty much everything, untill i found what it worked out at least for me. The digitizer and lcd ribbon cables comes, in the original part, with a sort of foam wich isolate each cable one from the next one, this foam it was not provided with the screen i bought for the replacement. so what i did is pull apart this foam from the original part really carefully with a razor blade and then i stuck it on the new ribbon cable. Done! problem solved !! i hope it helps as is an anoying failure excuse me if my english is not good but is not my native language
