This is a problem that has been vexing me. When I flash a ROM and set things up, I notice an annoying flickering of the GS3 screen when I scroll down a message. It happens with multiple ROMs (one notable exception is Clean Rom. Reflashing does not help. Now before I get flamed, I did a search on it (here and on the internet) and received no answer. There was one suggestion that the SwiftKey keyboard was the culprit. So I uninstalled SwiftKey to no avail. Any ideas? Thanks in advance.
