I'm on 4.2.2. Don't want to upgrade to 4.4.2 due to many negative feedback. But this issue just started a week or 2 ago. The wi-fi seems to turn itself on about every 4-6 hours when the phone is sitting idle and locked. I haven't narrowed it down further than that. When I unlock the phone, it connects to wi-fi right away, then I have to go back in and turn it off again. I like to keep it off to conserve the battery. No need to have it active when I hardly use it. I have the notification to notify when near open networks is unchecked. The mobile data does not turn itself on. Seems to be just the wi-fi. Any suggestions?
