My ATIV S is unbranded and unlocked and with the GDR2 update I now have Data Sense. Not sure about other manufacturers though.
Mine is also unbranded and unlocked ATIV S, and I have no datasenseIt has the latest OS update 8.0.10327.77. My firmware revision version is 2424.14.5.1 and hardware revision is 15.15.1.0. Could you share your firmware and hardware version, probably my versions are too old?
Thank you.
