WIFI keeps turning itself on since OTA

[Lea Brown]

I had this issue of wifi turning itself on as well. My problem was Settings>Location services: Use wireless networks, when I turned that off my phone hasn't turned wifi on since.

Sorry, let me add the quote so people know what solved my problem. It was just labelled "Location" in my phone, but sure enough I had the "use wireless networks" box checked under that category..

I finally figured out it was my battery saver app (Avast) that was turning WiFi on/off (and other things like screen rotation) to "optimize" WiFi.
