Hey there, Sophie here... So I was just on the internet when my phone just turned black.. the backlights were on.. so I hit the power button to turn on the screen and it shut of. When I turned it back on the baxklight no longer worked.. not even on the front where the home, menu, back, and search buttons are. :/ Anyone experience this? Advice? I've shut t off.. taken the battery out... to no avail.
