angela I don't see developer option
you might need to activate it. Go to "setting" > "about phone" and tap like 7 times on the "build number" 8at the end)
A message like "you're now a developer" should appear
angela i never ran fitefox or requested it to autostart and it is not showing in active app.
wait...? You have a browser that you don't use?
And the most stupid question: what a about de- and re-sinstall?
angela i think this is some exploit or ive been hacked. i should probably stoping using gos :-( cell phones are too frequently targeted
well... GOS shouldn't be blamed. But indeed, smart phones in general - as you said.
