This recently started happening to me (past three or four weeks). I will make or receive a phone call and after I hang up the phone, I notice the wifi has turned itself on. Sometimes, I notice it while I'm on the phone call and click my wifi widget to turn it off, but it immediately turns itself back on. The strangest part is that it doesn't happen every single phone call, but enough that I'm getting annoyed because I know the wifi is draining my battery searching for networks I don't want to connect to! I rarely even use wifi, so this is a major annoyance.
I've searched the internet and forums quite a bit and see some other people have the problem with it turning itself on, but none have mentioned that it only happens when they are on a phone call, so my problem is somewhat different, it seems. I'm thinking it might be an app, but even in looking at the running apps while on a phone call, I have no idea which could potentially be the culprit (if it is, in fact, an app problem). Does anyone else have this problem? Has anyone found a solution? Does anyone know of any known apps that have a tendency to automatically turn wifi on while on a phone call?
I have tried a battery pull and I had done a factory reset (for other reasons) over the summer, and haven't really added many new apps since then, so maybe an app updated and altered something. I do NOT want to do another factory reset, that was not fun.
Thanks to any and all that can help!
