I would take your phone to the store, after I've updated to android 5.0
everything in my phone got screwed up, I had tried what ever I could but
nothing was working, when I went in to community form at Verizon support, I
found lots ppl was having same problem as I did so I've decided to take my
phone to shop, they had wiped out everything out of my phone, now it's back
to my old phone except a cooling down notification is still there but it's
charging OK and WiFi is back also the speed had came back to what it was.
Good luck to you all who had updated with lollipop.
