wifi switch won't stay on
Settings, wiFi, when I try to slide the switch to turn on wiFi, it just turns off and two buttons flash at the bottom of phone, i.e. the return button on the right, and the menu button on the left. Any idea on how to get the switch to stay on so I can see and select a wiFi ssid? also no one wiped this phone, I have the prior owners pictures, music, and videos. Looks like the most recent pic was taken march 2015. I can figure out how to delete the old data but don't know how to get the wiFi radio to work, or test to see if it is just missing a driver. Just got it today via group on..
