    I saw a couple of other complaints today about WiFi turning itself on when the phone unlocks but so far no solutions. I'm having a similar problem. As long as the screen is on the WiFi stays off, but when the phone goes to sleep, it connects automatically.

    My phone is a Galaxy S3 with Jelly Bean 4.2 and my carrier is Straight Talk (and I know for a fact it's on the Verizon network). My sister has the same phone on the same network and is having the same problem excellent hers connects even when the phone is not in sleep mode or locked. (Mine was doing this earlier today. ) It just started out of the blue sometime last night or this morning. I checked all my recently-updated apps and uninstalled the only one that had WiFi access, as well as the only Go app we both have in common (I've had problems with Go before), with no results.

    I've also Googled several possible solutions, but they haven't helped. I don't have a signal optimizer option in my mobile network settings. The phone isn't trying to download anything or open any suspicious websites and it's not prompting me to update anything. There's been about a 1Mb uptick in my data usage today over yesterday, but I may have been online enough to account for that. It's killing my battery life and was interrupting my mobile browsing earlier, and I also wonder what information it's sharing that I have no control over. (The orange incoming data arrow is lit up almost constantly.)

    I know it's probably an app causing the WiFi to keep connecting, but how do I find it? I have a lot of custom settings I don't want to lose by uninstalling every app that has WiFi access to see if the problem stops. Even after eliminating the apps my sister and I don't have in common, there's still pretty long list.

    Thanks for any help.

    Welcome to Android Central! Try going to Settings>Wi-fi, tap Menu, then Advanced, and uncheck "Scanning always available."
