It's still running 4.1.2.... even my older phones... Galaxy Stellar.... have upgraded to 4.2. This is getting ridiculous. By the time I get 4.2.... Android 5 will be out! lol
Hello
Actually there are many phones out there still waiting on official updates to 4.2. The Galaxy Stellar which you mentioned is only officially updated to Android 4.1.2 (JZO54K). Some devices from Samsung (mainly the high end devices like S3/Note II) are rumored to be skipping the 4.2.2 upgrade entirely and going straight from 4.1.2 to 4.3.
Its also a safe bet that many of the low to mid ranged devices that were released on Android 4.0 and were upgraded to 4.1.2 might end up stuck on 4.1.2. It may not be worth the resources and not in the road map to update them any further.
