G4 Home Screens Changed Overnight

I woke up this morning to something weird! Overnight, my phone seems to have taken the pesky Sprint Default Update on it's own! My home screens reverted to 3 pages (I had 5 set up) plus it moved some of my app icons around. Even folders that I had set up were back to the app drawer! Did anyone ever have this happen? Is there a setting I need to change to NOT apply updates automatically? This is not a big issue but I really don't want it to happen again! This is on my new warranty replacement phone...my old LGG4 kept asking to install the Sprint Default Update but I was able to decline it. This phone seems to have updated it on it's own!

I'm pretty sure it was the Sprint Default OTA Update as it also re-added some of the bloat apps that I had previously deleted.
