Hello everybody. I've recently bought SGS4 GT-I9500, rooted it and installed GameKiller app(similar to CE on pc, memory scanner). When I try to run the app, it starts acting weird. I see message showing, that root access granted, BUT...but when it's on, it doesn't select application as well as restarts every 5-6 seconds. AND when I try to select application manually I get message "Root access required", any ideas? It's working perfectly on my SGS3 GT-I9300, just that I'm not going to use it anymore. Any help would be appretiated.
