Firmware updates don't uninstall with Factory Resets. They're installed to stay. The idea behind it is to erase any cached or working data that is conflicting pre- and post-update. If you made a Samsung Account, make sure to turn on backup/sync for the S-Apps, SMS/MMS, and Call Log.

The fact that it came from China alone makes the device itself suspect, if you're not aware of the cloning. Under About Device, what do the Software Version and Android version say?

If it ain't broke, use a sledge hammer.
