The Sammy G S3 has a counter of sorts. These past few years, Samsung has been very kind to us power users. We have been able to modify most of our Galaxy series devices as much as we wanted, without silly roadblocks as locked bootloaders and such. With the Galaxy S II, Samsung introduced a custom kernel flash counter and custom kernel warning triangle. On the Galaxy Note, Samsung tried hiding the data once more.On the Galaxy S III (among other new devices), Samsung has gone a step further, and has introduced a background service that runs on your device and checks for things such as a modified /system, apps running with root access, etc. For the moment, this service does not do anything malicious, but who knows what the future will bring ? Tracking of IMEI's that have ever ran root, disabling of services, etc ?
