I have had this problem since October. Since then my phone doesn't turn on my Wi-Fi and its super rare that my phone will connect. Well it says that it's connecting but short after it turns off and try's to turn it on again. I don't know what causing this problem. I really want to start using it again so I can get some games and checking out social media when I don't have my laptop or Ipad. Do you guys know what causing it? I would like to know.
