I have a galaxy S4 that was not used for several months. When I turned it back on,somehow parentalcontrols was turned on. When I tried to turn it off, it asked for a pin number. Now, since I did NOT turn it on, ( I'm 72, I don't have little kids!) I never created a pin number. Now I can't download apps. Is there a way to turn off the parentsl control thing without a pin number,or am I just screwed?
