Kit Kat gave life back to my Note 4. I didn't like Lollipop

I also downgraded from Lollipop 5.1.1 to Kitkat.
I had very very bad battery life and fingerprint problems.
All you have to do when you set up your phone is to NOT turn on the wifi. Stay on Mobile Data. Go to About Device. Uncheck Automatically Update. Then Check For Update. When the pop up comes up just click Never remeind me again. The update pop up will never show up again.
