I only use my LG G3 to take pictures. I was in Greece this week and I took different pictures and than I get a screen I never saw before.
There was a screen with enter back up pin but I really don't now what it is. There is also on other way to unlock and it and that is by enter your gmail-account and this I know.
But the problem is I turned of the WIFI to save battery so the Phone can't control my account.
It's also impossible to swipe down to get the screen to turn on WIFI, Rotation, Bluetooth, ...
How can I turn on the WIFI??? Please help me I have beautiful pictures and don't want to lose them!!!
