Immediately after the firmware update, both mine and my wife's S5 began to have screen issues. After a minute or so of non-activity, the screen begins to "quiver" (dimming and brightening rapidly like convulsing) as if it is trying to go to blank screen mode but has siezures instead. Is this a common problem with the update and will there be a fix?
Yikes! That's definitely strange behavior for any phone, janichol. And it's even stranger that you are both having this issue. Are either of you using any type of case or s-view cover? Does the screen eventually go dark or does it continue to shake until you press something? If you change your screen setting to go dark at 30 seconds instead of 1 minute, does the problem continue?
