I recently went to six flags, and when I got home my keyboard was not letting me type, and would freeze my phone then shut it off. I noticed soon after than my wifi is stuck in "turning on" mood. I have done a hard reset and it temporarily fixes my keyboard problem, but it goes back to doing the same thing. I have downloaded a keyboard app, so that's how I've been using it, but still no wifi. Is there anyone who can help?
