So, after the OS upgrade to 4.3 from 4.2.2, I've discovered that some applications that requires root access deny my system root, YES I've checked that my device is rooted, I have the stock kernel, stock firmware but I've rooted it via Odin3 with CF-AUTO ROOT, and yes the operation was successful. Now, the apps that I'm talking about is Gamecih app and all the other apps like that, and Screen recording apps, all of then denied my root. I've tried wifi kill app (that app works perfectly). So what could be the problem? The app or the OS version itself? Please find me a solution to fix this god dam problem, I'm using the Samsung Galaxy S3 LTE (GT-i9305) device.
