Meant to update this. A couple days later, the availability of the update came back, while I was within range of wifi. Hopped on wifi and downloaded/ installed it. No improvement in camera quality (not surprising, as camera wasn't listed within the upgrades). The list said:
-Some important security updates
-Several minor improvements to the general usability
So far I have not noticed any changes in my daily use.
The one thing that I have noticed, since the last update, is that there are constant wifi hijackings now. If the wifi is never switched on, it never shows up in the battery usage window.
Almost every day, the wifi shows up on the list, even if it doesn't log usage in the green bar. And most days I am using neither wifi, nor location, and I've got everything locked out from wifi as much as Cat's version of the OS allows me to. Of course, the reason I know to check the window to see if wifi has showed up, is that I can feel the phone get warm in my pocket (eating the battery).
It's almost as if I'm still getting the random, inexplicable wifi locks as I was before, but they disabled the status bar to attempt to hide how often it was happening.
The battery life on this phone could be amazing, but I'm progressively getting worse battery life as time goes on, because of all the wifi locks. I used to get a solid 2-3 days without Greenify, and then a solid 3 days once I installed Greenify. Now I barely get 2 days with Greenify, and there has been no real change in my installed apps or usage habits, just that I get a wifi or wake lock virtually every day that burns off the battery power. The only change I've made is to install their software updates, which seem to slowly be crippling the phone, both battery and camera-wise.
