[Android Central Question]

On 11/11, my phone had a system update, and I allowed it, and then it decided to update two more times, and I don't like the features that are now on the phone. I have no idea what the OS is, so if someone could walk me through to figure this out I would appreciate it!!

Aside from finding the file for the version you prefer, and backing everything up (because reverting to another version of the firmware gives you a factory fresh phone - any changes you've made are gone), flashing a Samsung phone is simple. See [Samsung] How to flash Stock ROM via ODIN. (Have something to do - it's boring, like watching grass grow in the winter.)
